I am using King Plus 800w Double Chips LED Grow Light Full Specturm for Greenhouse and Indoor Plant Flowering Growing (10w Leds)ing. Never used one before. Fan motors to cool light are producing an extreme amount of heat similar to HPS. Was under impression that low heat was one of the benefits...

Hi fam, After my successful go with The Cali Connection's femanized Girl Scout Cookies, I decided I wanted to go with something purple. I ended up with about 200 grams of Girl Scout Cookies, a low yielding strain, with my 400 watt setup. Due to heat issues and poor airflow, I had to turn the...

I would like to know how we are doing. I am doing a lot of trial and error with bag seeds and monitoring growth from planting to sprouting etc. I stunted the first 5 initially with light heat intensity. Round two did ok but also fail. Round three is now at 12 days. Again initial heat burn but...

First try at growing again. This happened about a week ago, and since I made some adjustments the other leaves look good. Was this heat, dry soil, or nutrients? I grow other things indoor and outdoor with no issues, but I have ever been able to fully grow cannibus. Thanks!
