Forgotten Diary

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

It’s been a long day potting these girls into there new home. All is looking well. Little bit of heat stress but ime sure they will cope 🤞

1/15-Started developing yellow/brown spots last week. Gave first feeding of FF Trio at 1/3 strength a couple days ago but she's continuing to look worse. More spots, lack of color and droopy leaves.

This end week 4 flowering last defoliation happy growing

this week is the penultimate transplant before flowering, my intention is two more weeks of vegetation so that they present the preflowers signaling the full ripening of this phase, healthy root, I noticed that it is very important for the results

I fiori iniziano ad essere più compatti, la temperatura è leggermente alta però per ora non ne soffrono.

We moved on to the second week. The root has already reached the end of the pot. I am amazed by the root development. I did not expect such a big root and I think it could have been transplanted a little earlier. On the twelfth day, he moved to a 22.7 L pot.

Mother: to the older sets that are in pot Gonna transplant dem new mother by the end of the week or next week...jus letting LST do it thing since I already started it New cutting first visible root in 8 day off of water only gonna hit them with a rooting mixture before end of week

Shes growing and stretching this lady has started to flower let the show begin !!! She's stretched quite abit over the past week lets see what else she does !! Thanks for the continued support ! -Happy Growing!

Heute stehen die beiden hübschen noch in der 48 Std Dunkelheit Phase. Morgen folgen die Bilder von der Ernte. Die beiden Ladys stehen für 48 Std in absoluter Dunkelheit bei einer Raumtemperatur von 27,7 Grad Celsius und 62% RLF

09/18/2021 At battle with catapillar this week Hand picking them off, some bud rot caused by catapillar's . Light defoiliating dying, yellowing leaves. Hand picking is tedious but well worth the effort. Feeding neptunes harvest 2-3-1 this is last week of feeding. Drinking lots of water this week gave each plant 2.0 gallons of Neptunes Harvest 2-3-1 hope it works out couldn't find fox farms, or big buds but I'm sure they will be fine.....will feed again on Friday then plain water for 3-4 weeks till harvest. Feeding should get them through the next two weeks then watering plain water should flush anything not needed by plants. Girls are thirsty this week, just in time for feeding! Neptunes Harvest seems to do the trick. Pistils piling on like crazy so one more feeding on Friday Of 2-3-1 and Week 7-8 banana peel tea, she should start Fattening up,and fading nicely by week 8-9.🙏🏻 The NPK value for banana skins is 0.6-0.4-11.5. But this is the value for dried banana skins. (I will make tea from peels) not sure of N-P-K Is for peel tea? But it works well in my opinion. Day # 6 week 6 applied gypsum today gypsum should help a little with PH issues,7.0 a little to alkaline but she will grow, but she thrive at 6.2 PH

Buds are fattening and getting frostier. Figured I would do a little flyover to give a better idea of size. Hopefully a harvest next week. Until then! 🌱🌳🔥💨

WEEK 12 - Both girls looks amazing covered in crystals 9L Pot is reciving the Final Part (Ripen) nuts for past 7 days, 3 more days and 3 days flush and harvest 12L Pot is getting there, today start I giving the Final Part Nuts (Ripen) and will harvest in 1.5 week

Switched the light to flower 2 days ago. Did some LST here and there to improve light penetration for the lower branches. I see a lot of new green in between the fan leaves. The light is off from 11pm till 11am and on from 11am till 11pm. Last time I watered her was 10 days ago. The 30Liter pot holds the water pretty good which makes it less stressful for me :) the pot was lighter today so I fed her around 8-10 Liters tap water where I added around 40ml of Bio Bloom (recommended is 50ml/10L). So far there are no signs of flower yet but I mean it’s only the second day after the switch.

We have pulled 4 of the 9 Gorilla Cookies as they looked ready, the other 5 we will monitor and pull as required. Some of the Buds look really awesome and they are sticky and smelly :) The 5 left in the tent are on an H20 only diet and will now have more room and light until they get chop chop :)
