I'm getting mixed messages related to RH and ...

BigBadLionstarted grow question 7y ago

I'm getting mixed messages related to RH and seedlings. Some people (and websites) say it should be between 45% to 60% during this stage but others say I should keep it over 60%. I know the roots are not very developed right now but.. what's the real number than I should aim for?

Hello ! Here are the full RH range for each time of the plants lives : Clones: 90% // Seedling (1st week): 80% // Early veg (2nd week): 70-80% // Growth(3/4 semaine): 60-70% // Vegetative phase (weeks 5/6 ): 50-70% // Early Flowering - Stretch (weeks 7/8 ): 50-70% // Flowering - Blooming (weeks 9/12 ): 50-60% // Late flowering : 30-40%. Of course they are just the best RH range you can reach for each stage of the plants life but it's not a "rule" as you can grow with lower RH at each stage but be careful about higher RH as it could lead to mold/bud rot/fungus. I hope it will help you 😁👍

hey there, at the seedling stage you're aiming for 70% + then as more leaves come and flowers appear you want to reduce that to avoid RH-related problems like fungus and bateria that can destroy your crop. So in the begging you're looking at 70% or more then in veg , 60%, then in flower 50%, later flower 30-40% why? because low RH promotes the development of trykes and also it avoids things like bud rot and other problems. You're doing well already ! good luck ! 🚀

The IDEAL conditions for clones and seedlings is a RH above 60%, around 80% actually; that does not mean that if you are below that range they will not grow, actually I never have that RH for my seedlings, my grow space is usually between 35% to 45% during seedling and veg stage and they grow fine; what might happen is they take a tiny wee bit longer to develop, but that's it. Cheers.

Clean them up or leave them alone I’m having trouble deciding if I should just let these girls keep going how I have been because they are absolutely amazing or should I do a big clean up and the canopy and lower canopy to allow some more light to penetrate for some fuller nugs?

My dark devil auto has just started to flower, not even a full week in yet. I have it planted in a 13” terra cotta pot (~2-2.5gallon) and there are a couple roots coming out of the bottom of the pot. Should I attempt to transplant into a bigger pot or is there anything I can do?

Too late for a harsh defoliation?Plants are in the middle of their 3rd week of flowering schedule, about 3' 8" tall from the stem, top two thirds are doing well, but the bottom branches are breaking off by just being brushed against when watering. Is it too late for a harsh lower defoliation?

Hey you fine horticulterists, another question thrown at you. When scouting online I've seen that some growers put their ladies thru a 24 hour dark period before harvesting. Is this something you do ? Is it required ? What are your preferences at harvest festival time ? 🕊️

Wondering when to add nutrients in coco? I heard after 3rd set of leaves. Some people say after 1st set. I use reverse osmosis with a mineralization filter although I have no idea what minerals are in there. My EC meter did not work when I received it.
