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 š¬
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.

What is growing out of my pot?Hey guys, not sure what this little guy is but it started growing out of my pot. I just noticed it today. Anyone have an idea?
I grow my plants indoor but I take them outside for 3-4 hours for actual sunlight.
Not sure if this is a formation of a new plant or part of my plant?

Growth Speed of AutoflowerIf I start three auto seeds of the same strain, is it expected that all three will be ready for harvest at the same time? My plants look fairly healthy, but it seems as if they are growing at different speeds. This was noted before the transfer to their final pot. Thanks.
