Once again, this week starts where the former one ended. With the exception of all the cables you can see in the first picture. I dared to install a minimalized version of the Raspi control only controlling the self-built humidifier and one blower/fan combination. I was very pleased to see how easily the simple diffusor can hold optimum VPD as long as temperatures are high and humidity tends to fall below optimum VPD. A single 10 seconds evaporation can hold the level for about 2–3 minutes. I am not pleased to see the Monsanto blowers rather underperform. It’s impossible to reduce humidity or temperature with both running on full speed, while a lifting of the tent door will bring immediate changes. With the Raspi/Arduino success so far*, I am thinking about using old Power Mac fans which are WCM controllable and use 12 V. At least one to increase air intake, and maybe even the blowers. * It wasn’t any problem at all to have the Arduino collect CO2 and soil moisture data, so after some more cable manufacturing (aka helpless soldering), I could extend the Raspi control. I’m still uncertain about the camera module (@trelorny impressed me with his time lapse videos). I don’t want to put the hardware into the tent with its not so electronics friendly climate, already risking some rare outages of the temp/hum sensor. But the camera module cannot be placed far away. So maybe I’ll use the 3A model I own as a spare part as a camera driver. Any maybe, if it works, invest in a better camera module. Mine is generation 1. Oh, and the ladies! Gave them slightly fertilised water yesterday, and even it or the better VPD yesterday or a combination of both make me believe bud growth is a bit more visible today. The smell in the morning when I open the tent to release accumulated humidity is outstanding. They were already thirsty on day 57 again, so pure RO + a bit of tap water until it spilled out of their pot’s bottoms. Many fan leaves turning autumnally now, and the smallest Sherbet suffered a bit from over-fertilisation as I wrote. But it this stage I don’t go for leaf beauty anymore. Just another learning: Don’t use differently sized pots anymore. Hard to feed them individually this way. VPD was mostly in best range yesterday, and I have the feeling it really supports their bud growth. I added an "Evening time" option to my Raspi control that allows the humidity to sink a selected time before lights shut down. That made it possible to have humidity in best range for most of the night time too. They were even dry again on day 58 morning. Another time just water. The blowers cannot cope with the flowers’ smell anymore, and so sometimes my flat cannot hide who shares it with me. Day 60 presents me with a problem: I’ll leave on Friday for a few days. Considering the microscope pictures are not from the tops buds: Would you say it’s safe to give them another week? Problem solved on day 61. Only clean water from now on, and next week will be their last. You won’t see any new pictures for some days now. Me too … Something I wanted to share with you before I leave: I just finished to update my grow box control with a new PWM fan hat that keeps the Raspi cool, while at the same an infrared sensor can now measure real leaf and additional ambient temperature. Setup is much cleaner and more robust now, but I wish my flux would not make the solder stick to the tip of the machine instead of making it flow and stick at the tiny tiny spots I have to hit …

Day 39 - Watered the Gold Leaf today by dunking it. 8.4 PH going in and 6.3 for the runoff. The PPM was only 500 or so, but I'm guessing it is because of the dunk. The soil test was still 5.3 on one side and up to 5.7 on the other. I checked right away so maybe it has gone up. GDP #1 seems to need water, but GDP #2 will need another day. The Gold Leaf is reaching the 25" limit for flipping, but the net should help show things down a little so the other 2 can catch up. Day 40 - Both GDPs needed water and got dunked. PH was 8.5 and the runoff showed 6.2. A soil PH check came back at 5.9. I am hoping that the small jump will help. I realized I would not be able to test the runoff with the stand and saucers I was using so i got new ones. This lowered my potential flipping height, but with the SCROG I am hoping to keep the goldleaf down long enough for the GDP to catch up. Day 41 - The Gold leaf is tall enough to bend down and the GDPs are almost there. I'm anxious to see how many bud sites I can get through the net before I defoliate and flip to flower. I don't think I should wait much longer with 3 plants in a 2x4 and the gold leaf getting close to 25 inches. Day 42 - 2x4 is too crowded so decided to order a 5x5 and move them over before I flip to flower. The gold Leaf is dry again. Watering with 3 gallons to try and get the PH up and the PPM down. The PH of the water I am using is 7.5 Day 43 - Watered Gold Leaf today. Going in the PH was 7.5 and the PPM 250. The runoff showed 5.9 and the PPM was 870. The soil test after work showed on one side as 6.1 and the other 6.0. Getting better, but I want to be closer to 6.5 before I flip them. The 5x5 tent will give me the room needed for that. Day 44 - Watered the GDPs today. The water going in had a PH of 7.5. The PPM was around 255. The runoff had a PH of 6.2 and a PPM of over 850. Both were very similar. At least one more week without nutes unless there is a problem. The ladies all seem to be showing a bit of magnesium deficiency. I started using a foliar spray for now with 1ml cal mag in 500ml of water with a PH of 6.5. Might need to add cal-mag to the next watering. The 2x4 is way too crowded with the 3 of them in there together. Hopefully the new tent shows up soon. Day 45 - The Gold Leaf is getting worse. It looks like lockout again. The other side of the spectrum this time. Probably too alkaline... 😒 From now on I will be feeding with water with a PH of 6.5. For now I added a few drops of micro and bloom to the foliar spray and applied it once more. It seems like it will need more water in a day or two so that should help.

Hey Cannafam happy weekend, Its been another mixed week for my gal, firstly i cocked up a bit by uping her feed on the PK side which shes had twice and ive given hercsome nute burn. Shes started maturing fast this week and reckon shes got about 2 weeks to go, so im just gonna lay off now and let her use upvwhats left in the soil. Her calyxs have been swelling nicely and shes now really frosty all over, i havent had the chance to but il try n do some good trich pics during the next week 😊 Environment wise ive had difficulty controlling humidity this week, shes at a VPD of 0.87 and the dehumidifiers been on 24/7. DLI remains at 45 but with light the same 62%(68 watts) but im going to reduce this also as she is lookin a little light stressed also. All in all shes looking solid in the buds department and really happy with her progress. Thats all from me this week, thanks for stopping by 😊✌️

Day 3 of flower now and stretching has been minimal. Expect weekly updates. Day 7, plant stretch has been even and manageable, foliage is dens tho, so at day 21 it will get an heavy defoliation and the lower growth cleaned up again.

The ladies have begun flowering. I have changed the lighting to Bloom. They're definitely a lot smaller than I thought they would be.

Plants with more direct UV showed much more purple across all 3 plants. The data shows that the number of terpenes in dried Cannabis flowers increases with a “No Red” light treatment for the final three days of production. Based upon these findings, we feel confident in recommending a spectrum control program that eliminates red light output from fixtures for the final 72 hours of the Cannabis flowering cycle. 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

Welcome to week 8! She’s still looking great and healthy. It seems that she’s still making some height but slowly also the buds getting bigger and bigger from day to day. At end of week 8 I probably have to adjust some branches to give them more light disposal and maybe doing some light defoliation. I’m still very happy with this strain and also with the performance of the growbox. Can’t wait to see how she’s producing nice, dense and thick buds

I was given the seed months before and just grew it on a whim with the LA and one of my own. I turned out great. It got the far right side of the tent and did well. She did even better with extra room up when the LA had to be moved. I jumped the gun on the flush and wish I could have given another week, but the down side to this specimen is prone to mold and my hands were tied. I do have another smaller plant with VERY dense buds that's sitting at 50-60% RH - not a sign of mold.. I'm happy with this plant.

As you can see, our macro lens arrived, we were able to take several photos and see the trichomes, we had never seen them so close before. We also noticed that many pistils have turned brown in the last days of this week but the trichomes are clear yet. The smell is getting stronger, reminds us of fresh fruits, mango and a little citrus. We are excited, she is healthy and smells good, but a little concerned with the development of buds and if they are within the standards for this week. Despite having many trichomes and the pistils turning brown, we are not noticing a significant fattening of the flowers (correct us if we are wrong). hahaha, noob stuff =)

FINAL WEEK! 14!!!! Lets go! I will start off by saying I am totally blown away with these plants! Not only did they grow way taller than expected, they performed very well considering my goof ups. The photos posted are the final stage of these plants, week 14. ILGM has really awesome genetics with these White Widow Autos. Each plant may have grown very differently but I predict they will all have high yields! They flourished using 100% dry organics but it would be interesting to see how they do using bottled nutrients or even synthetic. This will be my last flowering post before harvest details. All 5 plants were chopped on 5/6. I lightly wet trimmed and hung them all to dry in 50-55% RH back into the original tent. For final wet and dry weights I will post that all in my final harvest. Drying time may take 7 or more days. The final yield may surprise you! Stay tuned! Happy growing 😊
