Ultra-Violet The vegetative stage technically begins when a plant transitions out of early sprout development, usually defined by having 3 to 4 sets of true leaves or nodes where growth visibly speeds up.
Ultra-Violet Topped once, turned off IR @ nights, slowed vertical growth back down, and took off both of the very lowest internodes on each plant.

Ultra-Violet Remember that, however you are played, or by whom, your soul is in your keeping alone. Even though those who presume to play you be kings or men of power, when you stand before God, you cannot say, 'But I was told by others to do thus,' or that virtue was not convenient at the time. This will not suffice. Remember that.
Day:18
84°F and 65% RH (VPD) for the vegetative stage. Approximately 1.15kPa(assuming leaf temperature is about 2°F cooler than the air), which falls right into the ideal vegetative sweet spot (0.8kPa to 1.2kPa). At 1.15kPa, plants can draw water and nutrients efficiently without risking stress or wilting. It keeps the leaf pores (stomata) open, allowing for ideal carbon dioxide intake and maximizing vegetative growth. VPD is determined by the leaf's temperature, not just the ambient air. Because leaves usually run 1° to 3°F cooler than room air under bright grow lights, my actual VPD will be slightly lower, closer to the 1.0kPa mark. As she transitions from vegetative growth to flowering, one can gradually lower the humidity (to around 45–60%) and drop temperatures slightly to prevent disease from settling inside dense buds when they appear.
Night:6
At 70°F and 60% relative humidity, Vapor Pressure Deficit (VPD) is 0.86 kPa. This is right on the cusp of whats optimal for the vegetative stage. During the nighttime, plants generally close their stomata and undergo cellular respiration rather than photosynthesis. Transpiration slows to a near stop, making VPD less critical at night than during the day. However, maintaining a nighttime VPD between 0.8 and 1.0 kPa is highly beneficial in that it ensures the air is dry enough to prevent powdery mildew or bud rot, but moist enough to keep the plant from undergoing unnecessary stress. This range keeps the environment comfortable for cellular processes and prevents large atmospheric swings. Keeping it all flowing.
(Not pushing them yet, these are photoperiods)
The optimal soil (root zone) temperature for cellular root respiration and nutrient uptake in cannabis is between 68F & 72F This narrow range balances biological energy production (cellular respiration) with the dissolved oxygen levels in the soil, maximizing plant growth and health. Warmer soils hold significantly less dissolved oxygen. When soil temperature exceeds 74F oxygen depletion occurs, inhibiting cellular respiration almost entirely, At 68-72F root cells generate optimal adenosine triphosphate (ATP) via respiration to power root-tip elongation and the active transport of water and nutrients.

Ultra-Violet The nighttime VPD does not need to mirror the daytime VPD. Daytime VPD dictates the pull of water and nutrients, while nighttime VPD acts mostly as a prevention tool. A high nighttime VPD increases the risk of the leaf temperature dropping below the dew point, which can trigger bud rot and powdery mildew.
Switched down to 12's hours of light late in the week, changed spectrum, increased light intensity from 840umol up to 1150umol at current height. Overnight from 800ppm to 1500ppm; morning compensation point (microorganisms) 46-47 days from germination; she fills the canopy herself once the apical dominance is broken.
Measuring a plant's overnight CO2 emissions provides an accurate estimate of its dark respiration rate. Because photosynthesis stops in the dark, you are isolating the respiration process, which allows you to gauge how much stored energy (glucose) the plant has consumed and estimate the scale of oxidative phosphorylation. Oxidative phosphorylation is the final stage of respiration that generates the bulk of the plant's ATP (90%) and relies directly on the oxidation of these respiratory substrates NADH and FADH2 along with the consumption of oxygen.
From a thermodynamic standpoint. Growth is an energy-capturing process, and the rate of that growth is bound by the available free energy (Gibbs free energy) and the First Law of Thermodynamics. While the ceiling or upper limit is dictated by free energy (such as photosynthetically active radiation), the actual amount of growth relies on how the plant balances that energy with other limiting factors. These are often described as the nine cardinal parameters of plant growth. 4 Above, 5 Below. If any one of the 9 becomes bottlenecked, the entire plant's cycle is restricted.
Operating an 80F+ environment at night to force rapid carbon conversion comes with major drawbacks, as the biochemical processes work differently than the deductive logic suggests. While raising nighttime temperatures to 80F indeed accelerates respiration and speeds up the conversion of captured sugars (sink activity), doing so also radically increases the plant's overall metabolic baseline. If the plant's metabolic rate is artificially forced too high via heat, it can actually "burn" through more energy than it managed to assimilate during the day. This leads to carbohydrate starvation, stretching, and a net loss in final biomass yield.
400 ppm is near the standard ambient level; the plant's stomatal intake is the primary limiting factor, not the dark-reaction enzymes. To push 45 DLI without burning out the plant. Trying to force the conversion of a massive daylight DLI in a compressed time frame (12 hours) becomes highly inefficient because the Rubisco enzyme simply hits a saturation limit. To successfully convert a 45 DLI into dense, productive mass, the ambient CO2 generally needs to be elevated to the 1000 to 1200ppm range. This creates a steeper concentration gradient, driving the stomata to inhale CO2 fast enough to match the high photon energy.
It's not all about the amount of light, but the ratio too, as this will dictate growth through the ratio of phytohormones. In order for correct bud development, there needs to be a correct ratio of RGB. Different wavelengths have different penetration depths. When one grows using top-down lighting, only the entire canopy is limited to 2-3 layers of leaf, meaning there will only be correct bud development in those layers, regardless of getting 45DLI.
The biomass potential of a plant is linked to root mass. Generally, when a plant reaches its maximum biomass, you can help to chop off parts of the plant that are in less-than-efficient areas of the plant (low light) so that it can create new biomass growing towards the light. This is a very similar concept to nutrient recycling and plant autophagy itself.
Strength is the maximum potential, and power is the rate of conversion. You can have the biggest veg period of 18 weeks, and it means nothing; as soon as you start flowering, the chronological clock starts ticking. The only metric that matters to bud size is how much energy you convert each cycle, not by how long it took you to build the framework; it helps a lot nonetheless.
Not saying anyone should not defoliate for a reason, only that you should have one, and at the right time. Don't defoliate 30+% on autoflowers or 4 weeks into the flower period and expect an increase in yields; it doesn't work like that. There is room for dictating growth patterns and clearing out overcrowded nodes, but it needs to be done in veg because once that timer starts and buds start growing, it's all just energy conversion. One barely needs to defoliate at all in a 4x4 because with side lighting, turning a 2d canopy penetration into a 3d, even lower buds are 90% the quality and density of top ones. The rate of photosynthesis and the ultimate density of lower buds aren't just about the sheer number of photons PPFD. The specific ratio of R:G:B dictates canopy penetration and drives different photochemical reactions. The Electron Transport Rate (ETR) measures the speed at which electrons are driven through Photosystem II (PSII) during photosynthesis. The ratio of Red, Green, and Blue (RGB) light heavily dictates this rate.
Plant leaves continuously perform cellular respiration regardless of the time of day, using energy and oxygen to fuel essential metabolic maintenance. If you over-defoliate, the remaining canopy may be unable to produce enough net sugars during the day to offset the constant respiratory demands of the plant. Must balance fixation with assimilation; there's no point in capturing 45 DLI if you only convert 20% every cycle due to an extreme lack of respiratory capacity to perform cellular oxidative phosphorylation.
You can have a 4x4 canopy or a 4x4x4 canopy; yes, we know that side lights are not as effective at absorption from the sides or underneath, but it's not about DLI; it's never been just about efficiency; it's about the penetration ratios of RGB that drive ETR of/photosynthesis and trigger correct bud development. The size of each bud is its own ability to perform the ETR required for its own personal growth, and bud development is dictated by the ratio of RGB. It drives localised growth and acts as a regulatory switch for that development. Turgor pressure is another very important factor in understanding if you want big buds, for it is the "steam engine" that dictates the rate of bud expansion. Simply, a lot harder to achieve metabolically at ambient 75F than at, say, 86°F; the results speak for themselves.
Because buds have less chlorophyll, they do not suffer from the same photosynthetic shutdown that over-exposed, light-stressed leaves do. They can soak up direct light energy to swell in density and size. Their tolerance to intense light is heavily limited by temperature and humidity, but if you can control those temps and keep the rot away, buds have a much, much higher tolerance to high light than leaves. Beneficial to hammer with high light before trichomes appear. Balancing this with trichome maturity is key for rich terpene and flavonoid profiles; want it just right, somewhere in the middle, not too much, not too little. Find cannabis plants can defoliate themselves come harvest, given the right signals. Every last ounce of potential is recycled into buds by the plant itself (senseceance), given you can keep the level of conversion high enough to prompt a need to do so.
Get the canopy @ optimal PPFD range, 45-55DLI, then let the plant "stretch" the stems into a "PPFD range much higher, one that leaves don't like to grow in, but buds thrive in. What is optimal for a bud is different from what is optimal for a leaf photosynthetically. Genes provide the blueprint, but the environment dictates how, when, and if those genes are expressed. Must first signal the condition to increase the expression you want to exist through stress and response, cause and effect. A well-buffered CEC medium prevents extreme nutrient swings, allowing plants to maximise their dedicated genetic expression. Abundance generates abundance; the plant will aggressively nutrient recycle upon queue, the plantss intelligence defoliates itself, you just need to give her the ............nudge.
This is the key to move from "I grow buds" to "I grow colas".
A plant is either genetically expressing "growing" or "recycling" genes based on its nutrient starvation level in the medium. Constantly toggling between "growing" and "recycling" hormonal states creates a futile cycle that wastes valuable metabolic energy. Plants rely on sophisticated biochemical switches to manage this trade-off and prevent rapid fluctuations that disrupt that balance.
This energy inefficiency is a recognised biological challenge. Plants avoid this costly "flip-flopping" by using hierarchical master regulators (like the TOR and SnRK1 protein kinases) that act as strict molecular switches. These networks enforce cellular commitment to either growth or survival, preventing mixed signals.
This is something that was missing from previous grow attempts.
Under nutrient-rich conditions, TOR promotes protein synthesis, cell division, and structural expansion.
Under starvation, TOR is inhibited, and SnRK1 is activated. This triggers autophagy—where the plant breaks down old macromolecules and organelles to scavenge and reallocate essential nutrients to critical sinks.
"What's the point in flushing?"
The core idea behind a PK booster is to deliver a massive, concentrated surge of P&K exactly when buds are swelling in conjunction with a N starvation. Because these are short, targeted windows, the nutrients must be highly bioavailable so the plant can process them immediately. As soon as you go "organic," that's out the window. Much slower release, uncontrolled, very difficult to "spike". to cause the ratio that will initiate a response.
High-volume PK spikes rely strictly on the immediate uptake capabilities of mineral fertilisers. Making it far less efficient in organic/living soil setups.
When you use organic nutrients, it changes the dynamic with which the plant delivers and trades its nutrients; organic is always releasing new nutrients into the immediate EC. This prevents a lot of autophagic responses from occurring due to a constant stream of new nutrients into the immediate medium's EC. This can prevent nutrient starvation from being signalled.
PK boost is essentially just N starvation, triggering an autophagic response. Concentrated ratio of P&K while tapering off the Nitrogen base. To the plant, the sudden drop in Nitrogen registers as a severe environmental stressor—essentially, the beginning of starvation protocols. She aggressively strips nutrients and proteins from older leaves and vegetative structures and shuttles them directly to the developing flowers and fruit. Ta daaa. Call it a PK booster and sell it. Nothing to do with the P and K itself; it's the ratio immediately available in the medium triggering a nutrient recycling mechanism within the plant itself; all the "booster" sells is the trigger to the signal.
PK BOOST with 50% ammoniacal N signals floral maturation.
PK BOOST with N starvation signals nutrient recycling/sinking.
Very difficult to initiate a response when organic nutes are doing their thing. It takes 4x5x more water significantly to leach or wash ammonia out than it does nitrates. This can prevent triggering N starvation from having its normal impact.
Manipulating the C:N ratio in the medium. One autophagic response has multiple potential signal triggers. Nutrient starvation is not an option.

It's asking a lot of Rubisco regeneration to maintain 50 DLI in the 12 instead of 18. Raised the ambient CO2 to 1200 to 1500 ppm to achieve efficient gas exchange.
Not particularly recommended, but adding sugar to an indoor growing medium is a highly effective way to stimulate microbial activity, which rapidly breaks down the sugars and releases CO2 through cellular respiration. You can safely capture this CO2 to fertilize indoor crops and boost photosynthesis. While this process works, the setup requires precise understanding and management to avoid common indoor growing hazards.
The plant Carbon to Nitrogen C:N ratio defines the balance between structural carbon (sugars/cellulose) and nitrogen (proteins/enzymes). It acts as a master regulator of plant health, growth, and metabolism.
Rubisco (Ribulose-1,5-bisphosphate carboxylase/oxygenase) is the engine of photosynthesis responsible for fixing atmospheric CO2 into sugars. It is intimately tied to the C:N ratio for three primary reasons. It is the Plant’s Biggest Nitrogen Sink, Drives the Carbon Side, and it is the Nitrogen Control Knob. Understanding this relationship allows you to predict how plants respond to environmental stress or fertilizer.
Rubisco acts as the primary storage sink for leaf nitrogen, accounting for up to 30% to 50% of a C3 plant's soluble protein. Deep Green Leaves signal a rich abundance of both chlorophyll and Rubisco proteins. The plant possesses the heavy enzymatic machinery required to handle 1145 PPFD. Pale or yellowing leaves indicate a nitrogen deficiency. The plant is actively breaking down its own Rubisco to salvage nitrogen for newer growth, drastically reducing its light-tolerance threshold. Subtle difference, but understanding is important in order to be able to judge when to dial light intensity up and light intensity down, when to push, and when to back off. An extra dose of magnesium is vital if a plant is going to push through the growing pains of high-intensity lighting.
Foliar application of magnesium is an excellent and rapid way to assist with Rubisco regeneration within a plant, so long as it is applied correctly.
Spray strictly in the early morning or late evening, mixing your magnesium with a little fulvic acid or chelator, but only when she gets a little limey on top.
This, for me, is the experience of growing, akin to "riding the surf" maintaining efficient Rubisco regeneration through visual identification of the shade of green. Surf a razor-thin wave when balancing light intensity, nutrient availability, and transpiration to maximize Rubisco enzyme efficiency. Keeping the Calvin cycle fully charged without tipping into nutrient toxicity, light stress, or the dreaded chlorosis requires paying close attention to the visual cues the plant provides. By monitoring these subtle shifts in color, turgor pressure, and leaf posture, you adjust your environmental controls and surf that exact razor-thin wave.
Nute recycling acts as the vital execution mechanism for autophagy, which defines senescence. Natural senescence is a genetically programmed developmental stage aimed at nutrient recycling, whereas triggered autophagy is a rapid survival response activated by environmental stress. While both processes utilize the vacuole to break down cellular material, their triggers, selectivity, and overall goals are entirely different. Cannabis plant senescence is not separate from nutrient recycling protocols; rather, nutrient recycling is the primary physiological purpose of senescence, and autophagy serves as the core switch mechanism executing both processes. Understanding what makes leaves fade is not always senescence, but also strongly linked to Rubisco regeneration.
Takes about 24 to 48 hours to notice visible changes once the signals have initiated the autophagic response. Not too late at all. A little bit of fade from senescence 2 weeks from harvest is normal and genetically expected. Send the C:N 32:1 signal 1 week from harvest for the best effect in your organic grow.
Nitrate is nitrate; whether it oxidizes or not is not up for debate. If it's not sunk by the plant, you are smoking some, if not all of it, regardless of what your feelings are on the matter. Senescence is highly critical. It is the natural end-of-life stage where the plant redirects energy to ripen flowers. Properly managed, it breaks down harsh chlorophyll, allowing the terpenes (which provide taste and aroma) to peak. Harvesting outside this window leads to an "unripe" or degraded flavor comparable to going without.
To initiate the response, you can trigger it multiple ways; when growing synthetically, it's triggered by nutrient starvation, generally when the entire medium is flushed. This is more to do with N starvation than being entirely empty. Nonetheless. PK boosters are N starvation through maximizing P and K. (Generally only works for synthetic grows)
Normally, a medium only holds 10-30% of its nitrogen as ammoniacal, boosting this to 50% as it triggers the "ripen" signal, but you don't want to keep ammoniacal above 30% for more than 7-10 days if you can help it. It's a trigger mechanism no more.
PK BOOST with 50% ammoniacal N signals floral maturation.(ripen)
PK BOOST with N starvation signals nutrient recycling/sinking.
Because it's 99% organic delivery, maintaining the rhizosphere is critical. I will be adding carbon in the form of sugars (powdered molasses). It's almost impossible to empty a medium enough when microorganisms are constantly releasing nutrients into the direct EC. Very difficult to initiate starvation responses with ammoniacal nitrogen. Manipulating the C:N ratio is the key to triggering an autophagic response and resulting nutrient recycling in the last days using organic nutes and without having to flush.
Generally not recommended for new growers. So do what you want. But if you don't trigger the plant to dump its nitrates into root zones, you will smoke nitrates as NO3- does not oxidize during the dry and cure no matter what you do or how long you dry or cure. Nitrogen and its different forms are fundamentally different because nitrogen is used for so many various internal applications that plants require it to be in different forms, nitrate no3- is highly stable making it perfect for rigours of photosynthesis but this stability and protection from oxidation is exactly why nitrogen has different forms, nh4+ is made to be rapidly convertible to amino acids and enzymes as required, but once a predominant priority is no longer growth and the plant switches to ripening, you want as little nitrate in the plant as possible come harvest due to this stability nitrate will never oxidize during dry/cure, the plant can at most handle 10-15% of nitrogen reserve conversion (dry/cure) after that you are smoking whats left. No matter how many years you have been "growing", no matter how much ego boost you give yourself.
"Blah blah blah *clover steals valuable nutrients*
Crop and drop the clover come flipping to flower; its benefit comes from creating an airy and porous root zone. I don't need to crop and drop once the plant fills the canopy; she blots out the light, and the clovers die. This is the nitrogen the microorganisms use to convert carbon for respiration throughout the flowering stage, other than the hydrolyzed fish.

The main purpose of chlorophyll is to capture photons of energy. When growth is no longer a priority for a plant in nature, it will naturally sink its "no longer needed" nitrogen and switch pigments to carotene and anthocyanin, which are better-suited pigments for environmental protection rather than capturing photons (growth). This is because of all nutrients used by a plant, nitrogen in its nitrate form is highly stable and required for the rigours of electron capture, ammoniacal nitrogen readily evaporates into the air during cure/dry. The ripening stage is no longer about growth, but the main priority is protecting trichomes and opening up the oxidative capacity of the plant so it can focus 100% of filling those trichomes. Nitrogen in its elemental nitrate form is no longer required during ripening to the same degree as it was; the vast majority of growth is over. Understanding when to shift a plant's focus from rapid growth to maturation is the key to maximizing the trichome quality and terpene profile of the final product. That is the single most important decision you will make during a grow in terms of dictating smoothness, taste, and smell, I have found from my limited years of dedicated and driven study into the matter.
Synthetic nutrients maintain a near full nitrate ratio comparable to ammoniacal nitrogen, whereas organic nutrients maintain a supply of ammoniacal and convert only to nitrate what is needed. This is far more beneficial for organic growers when it comes to smoke smoothness, as the higher levels of ammoniacal nitrogen are far easier to dispose/convert than nitrates come harvest, cure/dry with far more efficient margins held within leaf/bud when it comes to conversion to aminos. A good dry and cure can go a long way to a quality smooth smoke, but without a proper senescence sequence or triggered autophagic sink of nitrogen, then you will be asking far more than can be expected from a dry/cure. It's one thing to sink the last 5-10% and convert the last drips to amino acids during the dry and cure, but leaving the plant fully charged with nitrogen in the form of nitrate is simply not going to taste good, no matter how much smoke you blow up your own ass or how long you have been growing. Means nothing. Smoke quality relies on pre-harvest physiology, not just the dry and cure! The dry and cure cannot fix poor pre-harvest metabolic states. A high-quality, smooth smoke requires correct signalling before harvest. While a proper dry and cure can gently soften the edges and convert the last 5-10% of sugars into amino acids, it fundamentally cannot perform magic on a fully fertilised plant. You cannot oxidise stable nitrates (+5 charge) into a smoother state during drying. Ultimately, accept it's going to be a heavy smoke and be grateful, onwards upwards!
The way in which ammoniacal nitrogen reacts to carbon sugars is critical in how it acts during oxidation and is responsible for oxidizing leftover sugars that can make the buds smoke harshly. Limited ammoniacal equals limited oxidation of excess carbons held within tissues. Just so you know, it's not an anecdotal rule that's unresolved and unsubstantiated. It's called the Maillard reaction. Signal triggers and stressors. Normally, you can only use 10-30% ammoniacal nitrogen, but as harvest closes, it is beneficial to increase this ratio 50% of ammoniacal as it assists in steering the plant towards maturation. Rather than running 50% ammoniacal nitrogen continuously until harvest, use it in short, targeted flushes/additions (e.g., 7 days) to slow internode elongation and hasten maturity. Use alongside forced larger "dry backs" (allowing the root zone to dry out significantly between watering events). Raising the Electrical Conductivity EC of the medium to create mild osmotic stress. Widening the day-to-night temperature difference and increasing the vapour pressure deficit VPD.
How would you like your cola's sir? Arm length, please, no gaps with trichomes as thick as snow.
Floral transition can be affected by a multitude of factors; too much or too little nitrogen can mess up gene expression and signal triggers. Nitrogen acts not just as a building block, but as a direct signaling molecule. It intricately intertwines to control when a plant transitions from vegetative to flowering. The Florigen gene and its rate of expression are highly sensitive to immediate levels. Nitrogen directly fuels cytokinin and auxin production, which dictate whether a plant allocates its energy to leafy vegetative growth or axillary bud and flower development(bud leaf ratio). Judging by the looks of 90% plant development on GD, looks to have possibly too much nitrogen ratio, which may skew developmental patterns.
The ratio of ammoniacal nitrogen NH4+ to nitrate NO3- is also a critical determinant of a plant's developmental timeline. Controlling this ratio alters internal signaling—nitrate promotes structural growth and can act as a floral signaling molecule, while ammonium pushes vegetative energy and affects cellular pH. As the photoperiod or environmental cues trigger flowering, most crops perform optimally by shifting to a highly nitrate-dominated diet. Keeping ammonium very low (around 5% to 10% of total nitrogen) in late flower prevents toxicity, stabilizes the rhizosphere pH, and ensures the plant directs its remaining energy toward floral ripening rather than green growth.
Similar to "stress tolerance" in that it invokes a response, or it doesn't. Too strong/many of the wrong signals tip some over the edge into "indecision", and can take forever to transition. Remember, plant genetics are not entirely dictated; they are complex combinations of genes 50% and environmental expression 50%, meaning the direct availability of nutrients/spectral composition dictates the developmental structure/ratio and phytohormone balance. Incorrect signals can strain development.
Sucrose (carbon sugars) in a medium is much more than a simple energy source; it acts as a core long-term signaling molecule that harmonizes carbon status with cues to initiate flowering. (be warned of using sugars tho, very strong oxygen scavenger that will cause direct competition between microorganisms and plants for oxygen if it's scarce. Sucrose is far more a signalling molecule for plants than glucose so it's important to distinguish and not just feed "sugars" to a medium unwittingly.
An increased ratio of reds at 660nm strongly promotes flowering. Add 15-30 min of 730nm at sunset for maximal signal induction of florigen using the Emerson effect.

Ultra-Violet Bud factor X triggers Induced Systemic Resistance (ISR) to trick the plant into thinking it is being attacked by insects. To do this, it uses a specialized blend of bioactive compounds (including chitosan oligosaccharide) and amino acid precursors like phenylalanine.
