Humidiy levels
m0useanswered grow question 3y ago
Check out this handy VPD chat, it gives you ideal RH and temp ranges for maximum plant growth.
It is a very useful tool and works quite well

Granted if you don't want to get that technical about it. these the are the rates I follow.
Seedling/sprout 1-3 weeks 75-80% RH
young-old plant in veg 60-65% RH
start of flower 50-55%
mid-end flower 40-45%
If your having issues keeping humidity up try an ultrasonic diffuser or if its keeping it down a small dehumidifier inside the tent, or outside it, removing ambient airs humidity before it goes inside the tent.
Best of luck and Happy Growing!

I always start whit 90/95 germinating phase and i reduce 5% each week,in the meanwhile i observe the situation and see if i need to decrease it faster or not.
But,we are talking about cannabis,she can grow almost in every situation 😁.
Good luck 👊🏽🍀

Considering that vpd is important. But generally speaking, yes you are ok at 60 or preflower. I’d try to be more 50-60 tho at that point

If you growing in water, humidity levels lower is acceptable

Can I treat thripes during flowering?Can you treat for thripes 2 weeks into flowering? I've treated once already with Monterey Organic garden spray with spinosad but I'm not sure if 1 treatment is enough. I also have Diatomaceous Earth but I haven't used it yet. Would I only spray the leaves or the entire plant?Week 11

Monster crop clones? What to do with them? Do you like using them? Mother plant? or flower it?I took a Clone from my Reserva Privada Skywalker Kush in week 2 of flowering. It's got 1 small pre flower on the top. Today I confirmed roots. Does these mean it's a monster crop clone? Does anyone have experience with monster crop clones? Keep as a mother or flower it later?

Droopy plants?Please help. Plants are super droopy and looks unhappy. Why are my plants so droopy? Under watering is not it, I raised my lights thinking it was burning them, it happened right after my first flower feed but no signs of nuts burn. I’m leaning towards overwatering? Any advice?

Regrow on late flowerWhat should I do in this situation? My flowers are very big but they are still growing. I think this is caused by the outside temperatures(30-35 degreesCelsius max in a day). While the other plant is everything alright because it stayed in a cooler spot. And when should I harvest

Should I start flushing her now?Should I start flushing her now or in a week or 2? She has been in flowering for about 5-6 weeks now. I'd like to wait for a bit more of a body high than purely head high. Not sure when you are supposed to flush then and how progress looks like for the plant the upcoming 2 weeks.

Porque una crece mas lento que sus hermanas?Amigos de Grow, mi germinacion fue un éxito 3/3, pero noto diferencia ya una es notablemente más pequeña que sus hermanas y quisiera saber porque paso eso.
Todas fueron plantadas con el mismo sustratos, mismo riego y todo lo demás igual para ambas. Entonces no se que lo causó.
