80% RH IN FLOWER?
guerillastarted grow question 3 years ago
Hi all
I know it's recommend to keep below 60% in flower..
I'm struggling to do this the last 2 weeks 😬
I got a small dehumidifier but it doesn't seem to do much!
Iv kept the air flow as high as possible..
Please can I get some advice on this!

It is almost impossible for a dehumidifier in a tent with a vent fan to keep the humidity down. The air in the tent is being changed much faster than the dehumidifier can handle. You often have to humidity control the room so the air being sucked into the tent is lower humidity.
Small Peltier dehumidifiers are almost useless. They simply cannot get relative humidity low enough. You really need a compressor style dehumidifier to approach the recommended 50% RH for flower.

Homedepot or Lowes, sell models around 150 that will do the job. I had to get one, the heat and humidity are too strong right now. I'm growing in a crawl space and the only way I can control it is with one. I bought one and it's the best thing I ever did, no more worries of mold at any time.

If the humidity is just high like that in the tent then add a more powerful air intake and exhaust, or leave the tent open when the lights are on. There are also bags you can buy to absorb humidity.

Dehumidifier recommendationsAny recommendations about a dehumidifier for the 4x4 grow tent? I think even with vacuuming run-off more frequently, I won't be able to get humidity consistently down below 60%. Amazon has some in the 45-90 USD range...Other. General questions

Bud rot! Should I harvest early?I wasn’t finding any mold or mildew except a few leaves until today. Had about 4days of rain and now there’s a bit of rot in every large bud it seems like. About 10 days of sun coming up now, so should I just cut the rot out and wait 1-2 weeks? Or chop now and make hash?

Overwatering?Why shes looks so sad? This is the end of week 4. The pot is not the best from the store, so I had to drill some hole on it, but maybe still hold the water inside? I watered 2 days ago, but soil still wet. I don't know. Maybe someone can prove it's looks like overwatering

Ripped branch from main steamI dropped my fan on a very nice branch and it pretty much got ripped off of the main steam. it was being held by a small little portion of thin plant material.Is it worth it trying to save the branch considering its an auto in pre flower, or am I better off cutting it off?
