air

Hi, I need help in setting up ventilation to make it better. For the moment I use a 400/500 m3/h extractor and nothing else. As it is summer, I have a lot of heat because I use several led panels. I have decided to upgrade because I have most of the equipment already, so if there is any...

Hi all Im planning a 5' X 5' X 7' tent with a 1000w MH/HPS combo. This will be my first run with the 1000w (previous 600w) and I'm worried about heat. So i guess the question is.... is it better to go with an air cooled hood and a passive intake on the tent or a normal hood with active...

I believe I overwatered my plants about 1 week ago while I was out of town. 2 of my plants took it really hard and died almost immediately. I thought the other two would survive but now it seems they dont look too happy either. The plants are about 40-50 cm (16-20 inch) from the light Strain...

Hey guys I'm about 3 weeks into flower and can't get the humidity sorted. It sits at about 45-60%, temps are ok, tend to go no further than 30oc, night time humidity is the issue. I bought an air con unit with dehumidifier but can't get it sorted. If I use the dry option on the unit it the...
