One of the hottest debates among marijuana growers is about bloom phase marijuana trimming.

LED grow lights for marijuana used to be a waste of time except for very small clone, sea of green, and autoflowering gardens. These days you can get LED grow lights that work as well as HID for full size photoperiod marijuana plants, while consuming less electricity, lasting longer, and generating less heat than HID. […]
The temperature and humidity of your indoor grow room are BIG factors in your plants’ performance. Michael Straumietis, founder and owner of the only hydroponics nutrients company that designs and tests its products on cannabis, remembers when he visited a 20-light grow op that had inadequate air conditioning. “They needed 6000 BTUs of cooling power […]
