Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X

Was gone for 4 days and Wholly cow has she stretched and grown! Update: did some defoliation, the roots were going into the gravity fed system so I trimmed the roots coming out of the bottom and elevated the pot for 4 hours to air prune the rest. Cut down one plant so she got to stretch out more!

Germination 19/08 Topped 10/09 LST 13/09 Transplant 27/09

This Do-si-Dos OG is so amazing it's just beutiful to see all that resin very early in flower just shining with the full Mediterranean sun hitting her right directly on those beautiful frosty nuggets,the aroma it's very OG but you can feel sweet tones too,very special OG,can't wait to harvest this girl,I definitely love this strain! 💚🌱💎😍

Update coming.

----- Week 7 ------ Still on rebound from nutrient deficiency , ( Magnesium) / Nutrient Lockout & maybe salt build up . I made too strong soil, With my additional amendments ( Which Gaia has most already ) . Basically double down on 4 of them . Working on the canopy and making sure the lower leafs are getting light , and even. It feels shes a week or two behind --------------------------------------------------------------- ----- AI Trouble Shooting ----- --------------------------------------------------------------- I use Claude AI to help with python / php programming, so I figured I'd run my soil recipe through this AI. Asked if there would be any issues, Pretty good response! Here was the response. ( I troubleshot the plant prior ) " Potential Issues: Salt Build-up: Worm castings + Bone Fish Meal together can lead to salt accumulation Watch for leaf tip burning or nutrient lockout Nutrient Overlap/Excess: Multiple calcium sources (Gypsum + Bone Fish Meal) Could potentially lock out magnesium uptake if too concentrated pH Considerations: Bone Fish Meal can lower pH over time Gypsum is pH neutral but can affect nutrient availability Deficiency Risks: Magnesium might become deficient due to high calcium levels Iron availability might be reduced due to pH fluctuations Nitrogen could become limited during heavy flowering "

Day 29: one plant is a beast but the other one i don’t know what happened there😂 Day 31: everything is going fine and the autopots are doing a great job! I’m using (torus hydro) to manage the ph! Mars hydro SP3000 High PPFD at 2.8 umol/j, average yield at 2.5g/w, increasing your yield 50% or more compared with old blurple and HPS lights, 300 watts output. Dimmer knob added, more convenient to adjust the brightness. Up to 30 lights can be daisy-chained and control together on just one light, or just have one lamp in 120x60 tent is perfect for light. https://www.instagram.com/marshydro_aliexpress2/

So It's been a great week! Apologies to anyone following as I'm a couple days late updating the diary this week due to work. Anyway, bud growth is really coming on! They're starting to fatten up nicely and the smell is just fantastic. Lots of trichomes as you can see from the pics and her parentage is really starting to show with those lovely bright orange pistils. The addition of PK warrior has certainly given them a boost but I have a feeling she is going to need longer than the advertised "8 weeks" to fully mature. We will see. Have a good week. 😁👍🌴

Man. 12 hours trimming fuck man and I'm moving on to photos now lmao I don't even know what I'm getting myself into. My goal into this venture was to learn how to grow weed ,not only for myself, but just as good as dispensaries do too. And with the way this plant turned out I gotta say I'm really getting somewhere. The resin on the plant was incredible. I kept scraping off my pruning shears with a razor and making little hash balls I'm gonna throw in a blunt later. And the smell! Oh God it's so strong when I was trimming I swear I was getting a temporary buzz just inhaling it constantly I loved it and the smell. Almost like a fruity cat piss type of smell wonderful. Will be adding a pic of root ball in the morning after a well earned night's sleep lmao

Been growing these in greenhouse while I didn't have space under the mars hydro was taking full advantage of the sun happy and healthy and cutting my veg time in half

This is when I knew I needed to go All in or Go home lol even tho I'm home already. So, I ordered a whole kit and said F it

I am still on holiday. My irrigation system seems to work. I can only show you a video from my Blink in the greenhouse, showing 24 hours from Friday to Saturday. Tropical Mirage is the cannabis plant in the front; she seems to be well. You can also see Euphoria in the back and right in front a giant basilicum hybrid and a Lila Luzi chili plant. Next sunday, I will be back with a more detailed report. Meanwhile, I am testing a few new strains in coffeeshops in Den Haag and Amsterdam :-).

So I think this is the week where I started to go a bit wrong. The Dr Earth I added on week 4 fixed my nutrient problem, however, I was impatient and added a bit more. As a result, I had 2-3 crispy, yellow leaves on the Quarter Pounder in the middle. Since then, I've upped my watering a bit and it seems to be fine. This week * Lights still at 15" * Giving about a gallon of water every other day, each. At this stage, I get barely any runoff, but stop when runoff is consistent. * Top dressed w/ more FFOF with some myco mixed in. See video for a better view of the nute burn.

6/15 Everything was dry this morning but the bags STILL had some heft. Much lighter though so I decided to water. I didn't realize how cold the hose is so I'll have to usecthe water inside or premix it. I watered everything at least a half gallon. Things are going great. I'll update as I go. UPDATE: IM GLAD I WATERED. ITS 73° OUT AND NICE AND SUNNY. 6/16 Foggy morning has turned into a sunny day! Plants are doing amazing. So glad I watered. I took a shit ton of pictures but they don't seem to be uploading. VERY FRUSTRATING TO TAKE THE TIME TO TAKE PICS AND VIDEO ONLY TO HAVE IT NOT UPLOAD. It's working now. I canceled out after I uploaded everything. Trying to upload again now. EDIT: EVERYTHING IS FIXED. I UPLOADED A BUNCH OF STUFF. PLANTS IN THE BACK AND THE FRONT SEEMED DRY AND LIGHT. I GAVE THE TWO 10'S AT LEAST A HALF GALLON. I GAVE THE THIRTY A GALLON AND SPLIT THE REMAINDER WITH THE 20'S. I MIXED UP 5 GALLONS. EVEN THOUGH THE PLANTS IN THE MIDDLE WERE DRY THEY STILL WERE FAIRLY HEAVY. IT IS SUNNY AND 80° WITH STRONG WIND. I'LL WATER THE OTHERS IF NEEDED BEFORE WE GET SOME RAIN. WE HAVE RAIN IN THE FORECAST SO ILL KEEP AN EYE OUT. IM VERY IMPRESSED WITH THE GROWTH IM SEEING. I NEED TO DO SOME MORE LST SOON AND PUT UP A TRELLIS. 6/17 I'm glad I watered those plants. Everything is looking GREAT! I didn't get pictures as I was in a hurry. The 3 plants in tje middle are dry on top bit about as heavy as the others. The wind doesn't go through them like the others. I would've watered but they looked happy and we are supposed to be getting rain. I'll be back over later and re-evaluate.

Spread this girl out a bit using some string and mild LST. She's responded super well and all the bud sites seem to be getting a nice dose from the TS1000 :) Bit late uploading this week but the pictures were taken back on Tuesday meaning this is still an accurately dated upload.

Woche 6 - Übergang zur Blütephase und erste Herausforderungen Die sechste Woche markierte den Übergang von der Vegetations- in die Blütephase. Bis zum Wochenende wurde weiterhin der Terra Vega Dünger verwendet, mit einem Verhältnis von 30 ml pro 10 Liter Wasser. Am Samstag, dem ersten Tag der Blütephase, wurde jedoch deutlich, dass ein Wechsel auf den Blütedünger nötig war. Leider führte die verspätete Umstellung auf die Canna Terra Bloom Linie zu einem leichten Nährstoffmangel, der sich in den ersten Tagen der Blüte zeigte. Anfang der ersten vollen Blütewoche wurde dies korrigiert, indem vollständig auf Canna Bloom umgestellt wurde. Die pH- und EC-Werte blieben stabil und optimal eingestellt. Die Temperaturen stiegen minimal an, blieben jedoch bei angenehmen 26 Grad. Mit Beginn der Blütephase startete der sogenannte Stretch, und die Pflanzen legten beeindruckende 2,5 cm pro Tag zu. Während dieser Woche wurden die ersten unteren Blätter entfernt – ein leichtes Lollipopping, um die Energie auf die oberen Bereiche zu konzentrieren. Die entfernten Blätter wurden getrocknet und sogar laminiert, um den Fortschritt dieses besonderen Grows festzuhalten. Es wurden ebenfalls einige kleinere Zweige und Blätter im unteren Bereich entfernt, um die Belüftung zu verbessern. Das eigentliche, umfassendere Lollipopping wird jedoch erst in zwei bis drei Wochen erfolgen. Trotz des anfänglichen Mangels aufgrund der zu späten Umstellung des Düngers blieben die Pflanzen insgesamt kräftig, gesund und wuchsen konstant weiter. Der Übergang in die Blütephase verlief somit erfolgreich, und die Pflanzen zeigten weiterhin ihr beeindruckendes Potenzial. ENGLISH Week 6 - Transition to Flowering and Initial Challenges The sixth week marked the transition from the vegetative to the flowering phase. Until the weekend, the Terra Vega fertilizer was still used at a ratio of 30 ml per 10 liters of water. On Saturday, the first day of flowering, it became clear that switching to the flowering fertilizer was necessary. Unfortunately, the late transition to the Canna Terra Bloom line caused a slight nutrient deficiency that appeared in the first few days of flowering. This was corrected at the beginning of the first full flowering week by fully switching to Canna Bloom. The pH and EC levels remained stable and optimally adjusted. Temperatures increased slightly but stayed at a comfortable 26 degrees. With the start of the flowering phase, the stretch began, with the plants growing an impressive 2.5 cm per day. During this week, the first lower leaves were removed—a light lollipopping to focus the energy on the upper parts. The removed leaves were dried and even laminated to document the progress of this unique grow. Some smaller branches and leaves were also removed from the lower areas to improve ventilation. However, the main lollipopping will take place in about two to three weeks. Despite the initial deficiency due to the late fertilizer switch, the plants remained overall strong, healthy, and continued to grow beautifully. The transition to the flowering phase was successful, and the plants continued to showcase their impressive potential.

Today I changed the CFL from 125>250w to try help hold a higher temperature overnight as it has been fairly cold in there. Roots are now touching the bottom of the pot they look healthy and white. Soon I will repot I got a bag of Coco today and some micorizor 😅 just to get new pots I've lost the old ones. Vegging fast these are already showing tiny preflowers starting to form and starting to smell slightly of blueberry muffins

Defoliated then cut down. They are full of autumn colours 😍 after drying they averaged 65-70g per plant, not bad for 1ltr pots. The high has an old school feel to it, it's very tastey but I don't smell or taste pineapple at all, more a car Polish/strong parsnip smell in the background. Recommended and after a 2 week cure very strong for an auto. I will grow again at some point.
