Is this a good or a bad thing?55 won't kill them, it will just make it grow slower. if you get it that temp during flowering your buds will turn purple.
It's an autoflower speed devil i thinki grew my plant at low temps and it is doing fine. just taking longer than it should. may differ depending on the strain.
If you put enough light in your grow area that should warm it up a lot. I have 16+ CFL's in my 24"x24"x96" flowering grow area and I have to work at keeping the temps down. You mentioned adding light, which would help, but more CFLs directly on the plants will help also. Are you using a fan to help circulate the air?Will my plants growwhen the ambient temperature is a constant 55°F? I live in a really old house and wstruggle to get the temps above that obviously, it will warm up some as the warmer weather gets here but i would like to know if i could get started now. Thanks
