Hey DGC! Thank you for all the knowledge and time you guys have invested in to helping us grow big, better and dank nugz! I have a question about RH for autoflowers. There seems to be a lot of mixed opinions on optimal RH for the different stages of autflower plants. Some say 40-60%, while others say upwards of 70-90%. What do you guys think? Is there a comparable difference between RH for autoflowers and photoperiods? I appreciate the time and love! PEACE
A high RH effects trichome production severely. After the transition into flower, auto or photo, you need humidity between 50-55% depending on temp. to produce something worth consuming.
I don’t see why Auto’s would respond differently to Relative Humidity than a photoperiod, or a feminized or a regular plant for that matter.
Probably originally grown in cold low humidity environment but when hybridized with other plants I would expect them to act more like the normal variety. Following vpd in veg is easy enough. Flower time you need that humidity dropped like mentioned above.
