I gave Isopropyl alcohol 70% equal parts water, 1 tsp cayenne, and kept enough for multiday application, what little population of aphids is left I shall catch them the next morning, opening the tent 10 min before lights on the clovers have yet to open, all the aphids hiding on the undersides are easily visible, still none ever went near cannabis plant. Clovers are far tastier it seems. The alcohol kills on contact, the idea was to saturate the leaves with a light foliar application, and once I was done I ran it through the canopy with my hands, making sure as much of the clover surface came in contact with the iso, once done, I turned on the fans and evaporated it quickly. The beautiful thing about Isopropyl is that it evaporates rapidly at room temperature, way below boiling point leaving behind zero residual so nothing seeps its way into root zones unless you spill it there. It is a magical solvent that leaves no trace that it was ever there. Resonant Frequency: A resonant frequency is the natural vibrating frequency of an object and is denoted as ‘f’ with a subscript zero (f0). When an object is in equilibrium with acting forces and can keep vibrating for a long time under perfect conditions, this phenomenon is resonance. In our daily life example of a resonant frequency is a pendulum. If we pull back the pendulum and leave, it will swing out and return at its resonant frequency. Objects combine to form a system, this system can have more than one resonance frequency. The resonant frequency is termed as the resonance frequency. The phenomena of resonant frequency used in the series circuit when the inductive reactance (XL) is equal to the capacitive reactance (XC). If the value of supply frequency is changed, we can observe that the value inductive reactance (XL) and capacitive reactance (XC) is also changed. Inductive reactance (XL) and capacitive reactance (XC) are inversely proportional to each other. When we increase the frequency, the value of XL increases, whereas the value of XC decreases. When we decrease the frequency, the value of XL decreases whereas the value of XC increases. At series resonance, when XL = XC. The mathematical equation of resonant frequency is: XL = 2πfL; XC = 1/2πfC XL = XC 2π f0L = 1/ 2πf0C ; f0=1/2π sqrt{LC} Where f0 is the resonant frequency, L is the inductance, C is the capacitance How to Calculate the Resonant Frequency of an Object? An object exposed to its resonant frequency can vibrate in symphony with the sound. The wavefronts pushing on the object will arrive at just the right time to push the object with greater and greater amplitude in each cycle. To get a clear idea of this concept one of the best examples is pushing a friend on a swing. If you push the swing randomly, the swing will not move very well but if you push the swing at a specific time, the swing will get higher and higher. Another example to find the resonant frequencies is to place the object next to a speaker and place a microphone attached to an oscilloscope next to the object. Then play the sound in the speaker at a given volume, and then without changing the volume slowly change the frequency. Now observe the oscilloscope, you will observe that at certain frequencies the amplitude of the wave, is proportional to the volume of the sound that the microphone is able to pick up. The frequency that is caught by the microphone will be greater than at surrounding frequencies. These are the resonant frequencies and are detectable as the sound energy absorbed by the object is re-emitted more efficiently at these frequencies. The precise moment that constructive interference happens the amplitude of the wave will spike at the precise frequency emitted. Q: Compute the resonant frequency of a circuit whose inductance is 25mH and capacitance is 5mu F? A: Known values are, L = 25mH = 25 x 10-3 H C = 5mu F = 5 x 10-6 F Formula for resonant frequency is, f0= 1/2π sqrt{LC}1/2π√L f0=1/2 ͯ 3.14√ (25 ͯ 10-3 ͯ 5 ͯ 10-6) = 450.384Hz Why Neodymium? Ferromagnetism is an exciting phenomenon observed in certain materials, known as ferromagnetic materials, that can retain their magnetization even after removing an external magnetic field. Ferromagnetic materials can become ferromagnets and interact strongly with other magnets and magnetic fields. A characteristic of ferromagnetic materials is their magnetization ability, distinguishing them from paramagnetic and diamagnetic materials, where weak magnetism exists temporarily. This unique property allows for making permanent magnets widely used in various applications such as motors, generators, speakers, and data storage devices. The ability to generate and maintain a magnetic field without the need for a constant external source of power makes ferromagnets highly valuable. An alloy of neodymium, iron, and boron discovered in the 1980s is ferromagnetic, yielding permanent magnets over 1000 times stronger than anything ever seen before. The name neodymium comes from the Greek neos didumous, which means "new twin." Neodymium magnets are made of an alloy of neodymium, boron, and iron. This allows them to simultaneously store impressive amounts of magnetic energy while being highly resistant to demagnetization. Because iron oxidizes quickly, neodymium magnets are coated to prevent rust from accumulating. The attraction between two neodymium magnets is so strong that if placed close enough together, they can collide and shatter. Neodymium magnets have an unusually high-temperature resistance, and they can even withstand heat exceeding 200 degrees Celsius. N50UH 1-1/2"OD x 1.065"ID x 3/8"

The purple Lemonade despite a very beautiful structure is a little worrying us because the flowers are swelling very slowly. We are afraid that they will remain small but it seems they are getting bigger so we wait a little longer to express ourselves even if the painta seems in excellent health. Bloom is slow.

7th week began today(Day 42). Girls are looking healthy and nice. They have devoured the whole growing space by now. The one on bottom right lost most of its roots while transplanting because of my mistake. She has made an incredible fast recovery, some of her leafs fell after the incident but she has now reached almost the same size as the others. * Is outdoor plant that was saved from the forest when the weather began to go too cold for hemp to develop any further. She is now inside since 3 weeks and is due to ripen in one week or so.

This week I had to remove my red light (sad because red leds are the most efficient one in terms of pffd per wattage) the reason for that is bleaching of the tips. Scientists found out that cultivars start bleaching if u hit 600 umol/m2/s red light (just red photons and not every strain bleaches). Besides that I did nothing to them. From now on I will try to keep the temps low but with a pretty small day/night temp difference. Now preservation of terps and maturing are my points of interests. Some nice colours are getting through … that was supported by some nitrogen deficiency. This was Not on purpose but better than burning them with nutrients. (Nitrogen is required to produce chlorophyll, which is Green. If u reduce the nitrogen towards the end you can support other pigments to come through.)

Height growth has stopped completely on plants 2, 3, and 4. Plant 1 is now at 22inches and most main tops breaching the trellis. Picked up some Full Tilt from FloraFlex to start throwing at them this week as they begin flush and start to finish out. Still running 3 grams per gallon(0.6 tsp per gallon or about 1 tbls per 5 gallons) of the B1&B2 from FloraFlex. This week I will begin cranking the tsw2000 from 75% slowly to 100% over the week and try to finish these girls out under the full 310 watts. Today I put it at 80% resulting in the highest tops on plant 4 around 500-550PPFD while the tops on 2 and 3 are receiving about 350 and plant 2 is receiving about 250. Will continue to increase the intensity and monitor their response. Hopefully in the next week or so we will start to see some color change and perhaps that runt will show us what she's been hiding. See ya in week 10!

After a week in the greenhouse, the ladies have taken root and are growing well. This despite the lack of sun and less than ideal temperatures. But summer is supposed to return this week. We'll see what happens then...

Ich habe die Lampe auf 80% Leistung gestellt und ende Woche zwei gegossen, die Pflanzen haben jetzt einen schönen schub gemacht und sind gut gewachsen. Die Blätter sind nun auch deutlich ausgeprägter. Update Tag 5 (Week 3): Ich habe die drei 10 Liter Stofftöpfe für die Pflanzen vorbereitet, dazu habe ich das Living Soil mit einer 10% Mischung angesetzt. Das Living Soil muss jetzt Dunkel und feucht bis zu 10 Tage stehen um sich um Topf gut zu verteilen. Mischung: 6L BioBizz Light Mix 3L BioBizz CoCo Mix 1L Florganics Paar Haferflocken 1.3 L Wasser Zudem habe ich mir die Pfanzen angeschaut und diese getopped sowie kleine Blätter unten am Stiel entfernt und nur die großen Triebe stehen lassen und gegossen.

There are no photos for a few days, I was away on a short vacation :) when I returned, I immediately started working with her, I cut off the single leaves, and used a little LST, Overall, the girl looks really beautiful;) strong, thick branches, I think she will give really tasty buds :) It is an autoflower, but it is not blooming yet, I think it will start soon, all my auto strains that I have grown before, started really earlier, but it is not a problem for me, and maybe even + she will be bigger with bigger flowers :) good luck to everyone :).

Day 37 from seed. 2nd day into week 6. -My focus for this week is to keep room temperatures under 75 degrees since I notice that my roots don’t like high nutrients temp. And since I m in DWC single 5 gallons bucket I don’t have the possibility to chill the water. So I have to keep the room temp lower then I wish to. - Day 41- I have to add nutrients and PH down every 12 hours. My PPM’s goes from 450 to 390 and my PH drift from 5.7 to 6.2 in less then 12 hours. Also I notice some rust on older levels (probably Ca/Mg deficiency). After some research (I’m new to this) I decided to up the nutrients to 600 PPM’s. Hopefully is a good decision. I will really appreciate some feedback.

April 26, 2024 Day 71 It's a new week and the start of late flower. It was also cleaning day. Both reservoirs have been cleaned out and are freshly loaded with new water. This week we are focusing on watering and nutrients. I may start to drop the dose until flush, over this week and the next. The light power will also be gradually dropped down over the next 2 weeks. Not much this week, I think I'll drop the DLI down to 43 mol/m²/d in the middle of the week. Next week I'll drop it down to 38 mol/m²/d. It all depends on what the plants look like. The plants are getting ready to hunker down and finish up. Both have decent sized buds and just need to finish swelling. I'd say another 2 weeks maybe? Flushing will start at some point over the next 2 weeks as well. Flushing won't be much of a big deal as it's just cleaning the reservoirs and running a week of Flawless Finish. The environment is changing a bit as well. I dropped the day temp down to 75° and the night temps to 65° or lower. Not cold enough to cause stress, but enough to get some purple I hope. The humidity is sitting at 47% and I'll be leaving it there unless somehow I can get it to go lower. For now it's pretty solid at 47% and everything looks great, so no need to worry. I'll be taking trichome pics every few days. One pic for each plant. No point in loading up the whole photo gallery with even more daily pics. Plus, the progression of trichomes isn't fast enough to really notice daily. So every 3 days should be fine. Grow System Environment: Temp: 74.2° RH: 47.7% VPD: 1.49 kPa April 27, 2024 Nothing happening today. Both ladies were inspected with no issues. I snipped a single leaf off of Banana Purple Punch B. Just one. Blocking bud sites. Banana Purple Punch A has some massive buds. About the size of golf balls. Maybe a bit smaller. They are still swelling and have a good 2 weeks left. Pistils are still mostly white, so that's a good sign for larger buds and more trichomes. Banana Purple Punch B is looking wonderful as ever. She doesn't seem to be suffering any issues with nutrient burn unlike her sister plant. She's perfectly healthy and has very nice bud production. The buds aren't quite as big as Banana Purple Punch A, but still nice and sizeable. The nutrient burn seems to have stopped for Banana Purple Punch A. So that's good. It should be perfectly fine now. Lighting is staying the same for the next couple of days. Although, I may keep it the same for the rest of the week. The environment is excellent now. It's raining today and the humidity is still at 47%. I did get it down to 44% for most of the afternoon yesterday, so I may be able to keep it down after the rain stops. Or just wait for the afternoon and see what happens. Either way, the humidity is now at 47% and the temp is at 76.8°. The VPD is at 1.57 kPa. A tiny bit high, but still well within range. Last night's temp was a little high at 69°. I'll have to drop the temp lower again to get that 65° sweet spot. Grow System Environment: Temp: 74.4° RH: 45.7% VPD: 1.55 kPa April 28, 2024 Not much to do today. I mixed a new batch of nutrients for both plants. The only difference is that I cut the Overdrive in half down to 2 ml/gal. Neither plant needs it, but now it's mixed and ready to go. I may end up filling the reservoirs tonight as it stands. Or later this afternoon. I don't think they will last til tomorrow morning. Both plants are putting off a wonderful aroma. I honestly can't describe it. Like sweet and kind of a hint of banana and a bit heady. Trichome production is picking up quickly. The pistils are starting to turn orange as well. They are definitely in the late flowering stage. I think I'll start dropping the nutrients for the next watering. And I'll drop the DLI down to 40 mol/m²/d tomorrow I think. Not much else to say about nutrients or lighting, so moving on to the environment. It's a warm humid day out and raining off and on. My whole environment is wonky, with humidity being at 57% and the temp at 77°. I turned the AC on about an hour ago and the temp went down to 75°, and humidity up to 60%. I think I'll crank the AC all the way down. And hopefully get rid of the humidity with the temp being a bit lower than perfect. Update: I ended up adding about a half gallon of plain water to both reservoirs. Just Incase I have nutrient lockout or something. They should go through that by tomorrow afternoon. Maybe late evening. Grow System Environment: Temp: 75.6° RH: 52.8% VPD: 1.39 kPa April 29, 2024 No watering today. I'm still waiting for the plain water work it's way through. However, I did drop the light power. Both ladies look great. Big buds, great scent and nice color. I'm not seeing any fade yet, but the nutrient burn is still there. I hope it will fix itself with the plain water. And then maybe fading will start. These two need a good 2 weeks or so before harvest. The lighting, as I said, was changed today. I dropped the power down to 70% to get as close as possible to 40 mol/m²/d. I may have to drop it another 10%. I'm not too sure. I'll check the DLI again when I'm more awake. (I'm finally on my second cup of coffee. Lol) Looks good though. Just around where I want it to be. But there are a lot of spots where the DLI is a bit high at 43 mol/m²/d. The tallest tops are also kind of high at 45 mol/m²/d. Again, I'll double check on a couple hours, but it should be fine. The environment is wonky again today. The temp is fine, but the humidity is still high at 60% and I don't see a way to drop it again. Not with the current weather. Hopefully I can get it down with some heat. The AC method did not work. Well, it maybe will work tonight. I'll be dropping that bad boy down to 59° tonight and hopefully it will do what I need it to. Grow System Environment: Temp: 74.2° RH: 59.8% VPD: 1.15 kPa April 30, 2024 Watering day. The reservoirs were both nearly empty and there was just enough space for a full gallon in each one. It's the normal nutrient dose with Overdrive being at 2 ml/gal. These two plants are looking mighty fine. Excellent bud swelling and trichome production. I'm definitely going to be wet trimming them instead of my normal dry trim. I may leave the bods on the branches and do a partial wet trim, or I guess mostly wet trim. They smell great! Very strong aroma now. I swear they smell like artificial grape. I can't describe it any other way. Grape and pungent. Awesome. So far the light seems to be fine. No reaching or showing any signs of lack of lighting. They look pretty happy. Although, Banana Purple Punch A is a bit sad from nutrient burn. Banana Purple Punch B however didn't seem to have much of a problem with the burn. The environment is still pretty wonky. High humidity again. I can control the temp pretty easily, but the humidity is another issue. It's currently sitting at 56% and I'm holding the temp at 76°. Grow System Environment: Temp: 75.5° RH: 57.0% VPD: 1.26 kPa May 1, 2024 Not a whole lot going on today. No water needed, no light changes. I rotated both ladies 180° so now they are getting light on other sides. I'll leave them like this for the rest of the grow I think. Banana Purple Punch A actually fits better in the new position. Less wall touching and about the same neighboring plant touching. I also removed 3 leaves. Ones that were misshapen from being crushed against the tent walls. Banana Purple Punch B seems to fit a little better in the new position, mostly because of her sister plant. More room on the outside and a little less room inside. No leaves were removed today. I'll reserve that for the last 2 days of the grow cycle. Then I'll do a massive defoliation and then a wet trim. It's humid here right now and I need the space. Otherwise I'd stick with dry trimming. But I can't hold up the tent for 3 more weeks. I have other plants getting ready to be planted in their final containers. Like a week for that, I might be able to squeeze a week and a half, but that's it. They will have a space, but the main tent is where they will need to be. Not a 2x2 dry tent. I'll work it how I need to I guess. Anyway, both ladies look great! Trichome production is coming along nicely as well. They are very smelly now and I love it. They are also still packing on weight I think. Not a ton, but the buds are clearly getting denser now that some of the pistils are starting to turn orange. I'd say another 2 weeks on these two. As I said, the lighting hasn't changed at all. Not for another few days to a week. Then it will have another power drop. Until then, we are staying at a DLI of 40 mol/m²/d. It's roughly 38 mol/m²/d on the outer part of the canopy. The environment is STILL wonky. I cannot for the life of me get that damned humidity down at all. Not with a dehumidifier, not with the heat cranked, not with the AC cranked. I'll try my big dehumidifier in my room, but the humidity is like 49% and frankly I'd rather the room humidity stay there. Much easier to breathe. However, the humidity in the tent is suffering at 59% while the temp is hanging out still at 76° Grow System Environment: Temp: 75.2° RH: 56.1% VPD: 1.27 kPa May 2, 2024 Not a lot going on today. No watering needed, no trimming, nothing. I found a broken bud on Banana Purple Punch A. It must have been from when it was against the wall, or too close to the other plants and got stuck on a branch while I was rotating. Oh well. It's a lower bud, so not huge. It's also the last day of the week and that means new videos! For the rest of the grow, I'll be making weekly videos of the individual plants. So that will.be this week and the next 2 weeks or so. Banana Purple Punch A looks great aside from that one broken bud. Her buds are fat and thick. Super dense from what I can see. I would like to note that the fade hasn't started yet, so we still have that 2 weeks left. Unless it starts in the next day or 2, I'll be banking on 2 weeks. Banana Purple Punch B is still compact as ever, but her buds are getting fatter everyday and of all the plants in the tent, she has done the best with the nutrients. Very little burn and didn't seem to be bothered by it. Maybe I did something early on to have such a small plant, but still. I think I can bank on 2 oz from each plant. Maybe 3 oz. It's really nothing compared to previous grows, but as I said before, as long as it's fire, I'm happy. Trichome production on both plants is fantastic. They are loaded from top to bottom. And building more and more everyday. There's still plenty of time left for there 2 as well. Most of the trichomes are clear with about 20% being cloudy and sparsely amber. That's another sign that they need another couple of weeks. Maybe slightly less. I increased the light power yesterday back up to 80%. I think I was a bit early on the intensity drop, so I'll drop it again in a few days I think. Around mid week coming up. Now we are running a DLI of 43 mol/m²/d inside and 40 mol/m²/d on the outside. The environment kinda fixed itself, but not to the ideal climate. It's still at 55% humidity. Better than 60%, but still not good enough. It needs to be below 50%. However, I can still control the temp and I have it at 74.5°. I'll turn it up a bit and see if I can clear out the last 5% of the humidity. Grow System Environment: Temp: 73.7° RH: 55.2% VPD: 1.24 kPa Update: I added a couple test videos to see if they would upload. Success!

I dont know why Leg OG growing slowly? Today is day 14 for WW und Leg OG and 13 for Critical. White Widow growing so fast. I think she is easy to grow and perfect for SCROG or LST. WITH the next watering I will start to use Sensi Grow A + B.

Check these forming buds out this week on BMR. These look like some of the biggest buds I will have ever grown. Not a ton of smell yet, what terpenes are there seem a bit woody with an underlying sweetness. Continuing with the sugar sources for the microbial life, the plants aren't showing any signs of deficiency so I'm just letting them ride at this point. Let's keep swelling!

Nice week. Transition to center mass continues - the frost builds and the aromas are incredible. Purple berry kush - slight touch and the blast of berry kush. I showed it to a non smoker - he smelt it and said - smells like I shouldn’t be here 😂😂😂. Upcoming week will be weening off the finisher and phasing in for a full flush. Divergence on two plants in the tent as they were planted later so will keep the blooming fed.
