Water chiller and air conditioning. Hydro is expensive when you have to buy all the equipment. Plus you should have backup of all your equipment.

Its been in floration for two weeks and the pistils are already showing, but now two little sacs appeared. Is this a male sign? It was supposed to be a feminized seed

Harvest and Varying Trichomes
For one of my OG Kush Autos, the trichomes on the main cola are clear/cloudy and the pistils are half white, half brown. BUT, some of the trichomes on the sugar leaves on one the lower colas are amber. What's the move? Chill out? Wait for the bud trichomes? Partial chop?

Are these pollen sacs developing? Is my plant turning hermaphrodite? Can anything be done?
First-time grower here. Im growing 2 Trizzlers Autoflowers and I'm 30 days in. This morning I noticed what I believe to be pollen sacs forming on one of the plants. Has my plant Hermied? and if so is there anything that can be done?

Just about week 5 of flower and buds starting get phat. Plants are pretty bushy, curious if defoliation of fan leaves is an option this late? or what I should do to improve light and air flow ? most leaves already tucked away that I can. Maybe I should leave it as is??

Recomendacion de abono.
Me gustaría saber que abono me recomendáis para el siguiente crecimiento. No me gustaría llegar al fin de la floración con una falta de nutrientes tan aguda como la actual.

Higher temps due to dehumidifier, HELP!!!?
High temps due to dehumidifier? Help? I currently have my dehumidifier inside my grow tent and it is end of week 3 flower. Because of the dehumidifier constantly trying to keep humidity below 50%, the temps are consistently between 28 and 32 degrees Celsius. Any ideas?

if you have placed a seed in a cup of water for a few hours to germinate, can you take it out if you change your mind if it has not opened yet? Cant decide how many plants I want in the new tent 3, 4, or 5?

Deficiency?
Hey everybody, I’ve never really dealt with deficiencies in autos as most of my experience is with growing photos outdoors. Does this look like a magnesium deficiency? These just appeared over night on just two of my larger growing white widow autos. Please let me know, thanks!
