Day 21

I finally build a cabinet and start some HID growing. Iā??m using a 400w metal halide from HTG Supplies (via eBay) that I bought last year and never really got to use. As it turns out, HID is really f***ing hot and I had heat issues the entire grow. I had an 80cfm fan venting the air out into my attic and quite frankly, it wasnā??t enough. For anyone planning on growing in small enclosed spaces with HID, I highly recommend an enclosed reflector and at least a 250cfm fan, if not more (400cfm, 500cfmā?¦). Heat is something that shouldnā??t be an issue and can cause some subtle but very real problems. My final harvest was half of what it should be, and heat was a large factor.
At temperatures of 95+ degrees F, cannabis basically stops growing. The fact that my box was between 92-98 degrees for the majority of the grow means the plants were stressed and didnā??t grow as much as they could.
You can still see the leaves yellowing and burning in these pics.
dgsgandalf Reviewed by dgsgandalf on . LR2 under a 400w MH Here it is guys, my complete indoor Lowrider 2 grow. Started under cflā??s and finished under a 400w Metal Halide in 6ā? then 12ā? pots. I used 2 different Miracle Grow vegetable plant foods, 1 for vegetative growth and 1 for flowering. I believe they were 24-8-16 and 15-30-15. The details of the grow are explained below with pictures. Enjoy! P.S. This grow actually took place some time ago. Iā??m just now getting around to posting the log and pics Rating: 5
