Hi. I have no idea about your question as I'm not experienced enough to answer your question. But what i know for sure is that 70°F ambient air temperature specially under LEDs can't warm leaves enough to do thier metabolic reactions efficiently. Ideal LST is around 84-86°F without CO2...

Today is day 22 of flowering. 3 weeks ago, right after initiating flowering i did some defoliations. I cut down some growth tips that i shouldn't. After buds started to form i recognized the wrong defoliation i did. But im still so gald what I've done as first grow. :)

Should i? How? Day 4 of flowering after 11 weeks veg. ​​​​​​​

First day in flowering :). I have 8 weeks to go :) Nebula you are the best :)

Green75 i owe you and Nebula's great articles :) ;). Thank you, both of you 2 :)

She's growing well. I'm happy with what I've done as first grow. Thank you so much Nebula.

i like her :)

My plants are in day 64 of veg 20-4 schedule light. Im not ready to initiate flowering yet but today i saw these pistils as pictured below. I dont know what i have to do now. Should i initiate flowring or i can back to veg by continuing 20-4 schedule. Why did they start flowering?

HID 600w, LED 137w

Hi everyone. A girl of mine under LED has a symptom at mid to top of her. Any explanation please? What should i do? It's spreading too fast and i dont even know what it is. Mn deficiency?

2 days after supercroping, an hour after LST

I was bussy. here are pics. What should i do now?

Hi. I have plants both under HID and LED in a tent. Generally, leaves under HID light get warm more than LED. I'm also running CO2 manually and because of that i need higher light intensity as normal. I know when plants get high level of light they need warmer temperature and reletitive...

if you know your panel emits correct spectrum(i think it dose) then you need 16-18 true watt of led for squad feet for veg and 32-36(at least) watt for flowering. If your want to cover 8sf for veg so you need 126 watt led panel. if you thought you may need both for veg so you should have bought...

You may know VPD determines the transpiration rate. With brighter light leaves get more light (and it increases leaves temperature) so they need more CO2 to perform photosynthesis. To absorb more CO2 stomata need to stay open. But as leaves temperature increases by brighter light, leaves vapor...

i have to defoliate this one every time before going bed and after waking up. Gn every one. cya later.

You may know or not, it's my first grow. I'm just done with my first defoliation too. It taught me so many things. Defoliation lets the lower growth tips to breath CO2 getting light and become a cola, No fan leaf is able to become a cole. I think lower fan leaves and the ones have been blocked...

It's getting cold here. There is a label at the back of my gas heater that uses NG saying 3600 Kcal/hr. I checked my gas station and found 8600 Kcal/m3 when my specific NG(must of it is methane, CH4) is burning. burning 1 mol NG produce 1 mol CO2 CH4 + 2O2 = CO2 + 2H2O 3600 (Kcal/hr) / 8600...

Its my first grow and I'm gald with her green color after seeing her 2 weeks yellow, brown and black. ​​​​​​​
