What is safe RH level during early flowering?
noobnoobstarted grow question 4 years ago
Looks like weather's gonna be a bitch. Forecast for next 10 days is 65-75% RH. Now it's 60 indoors and 64 in tent. Got some silica gel in tent, next I will put portable AC/dehumidifier next to tent. What would be good RH that I should aim for?

With your temperatures you will want to maintain 52.5% to 62.5% during this phase of early flower.
During mid and late flower if you maintain the exact same temperatures its 40% to 50%.
If the temperatures change the indicated RH value changes as well.

The higher the temperature the higher the "safe" humidity and lower temps, lower humidity.
There is a chart for it but i can't upload pictures and im not into transcribing 10000 numbers 1 by 1.
So temps like 35°C your gonna want 70/75% RH.
Temps like 20°C your gonna want 40/45% RH.
Its all about transpiration, people can tell you an exact value for RH for each stage but unless you keep the temperature at exactly inbetween 25°C and 28°C there is no point to lower the humidity if you have temperatures of 32 or 33°C because it would hurt the plant.
Got it?

if possible, Judging by photos, roughly estimating, can anyone tell when WW1 will be ready for harvest? (Recent photos are marked WW1 week 9 end). Lower buds are very loose but have some brown hairs. Tichomes look clear / cloudy to me through 40x loupe. Cheers!Week 9

What did I do wrong here. These girls are growing slow. They were slow before I topped them, which I know I messed up there. But there’s not much going on. They look healthy just sooo slow growing. Any suggestions on what to do to fix this? Or just wait and see what happens?Week 6

In the left part of the first photo it shows how almost all look right now. All my girls are having 4-8 colas, ~40% of the bottom to up growth was removed.
Should I remove almost all or all secondary shoots from the colas?Or should I let some on sides and remove the middle ones?Week 11

Gonna put in 5 Autoflowers in this tent (12/12) for at least 1 week (to gain time). 20/4 after.
Do you guys think it will have any noticble effect on the yield in the end?
What you think about 1½ weeks? I would imagine that's the limit.
Interested to hear your thoughts
