re: Xlr8's Psychedelic Bloom Party Extravaganza
Great post X! I've also seen people make it through cloning and veg with lower rh and no problems. Do you like to bring it down gradually, or just as low as you can from the flip? I'm sending you "mental" reps because I have to spread some around
This is just my thinking here, based on observation, not something I've studied up on extensively...
Personally, I'd probably prefer to let it be a little higher until mid-late flower (30-40%), then lowest toward the very end to really bring the trichs out. But, certain times of year I just let the dryness be what it is (if I don't feel like it's too
high), as I hate the extra work of adding moisture to the air, and it's something you obviously have to be careful doing as moisture attracts mold and bugs. This time of year, it's hard for me to keep it above 35% even if I wanted to. I'd guess it probably has some affect on
yield when it gets below 30% regularly during bloom. In a perfect world (just my version of it), I'd probably try to keep it at around 30-35% for most of bloom, and try dropping it even lower, if possible, the last week or so.
Mostly, I wanted to share that I think the dry environment contributes to
trichome production, and that I don't think it's a plant killer or problem to have low RH if your temps and environment are fine otherwise. I used to think you would kill your plants or stop them in their tracks with low RH like this, but I know better now. I still see a lot of newer growers blame problems on low RH, when it's probably something else.
Like I mentioned, the lower RH may have
some impact on growth/yield if it's too low or too prolonged. It also might be dicey with soil or drain to waste plants that don't have constant access to water like active hydro systems. This is where goals matter a bit, too. I'm okay losing a
little yield for better trichome production, since I'm just supplying my own needs. I still want nice yield, but from a priority standpoint, my goals might be different than some growers.
Oh, and thanks for the mental reps, I'll take 'em!
