Hello Fellow Michigan Medical Growers , I havn't been to this site since I was a new grower back in late 08-early 09 , This site helped me learn how to grow and I owe a big thanks to everyone that posts on it . Now I see you have been doin good on your grow I just wanna throw a few things out there , For Veg use 400 watt metal halides best watt per lumen , t5's are nice low heat , but don't come close to MH's. they are actually even more $ to run for lumen to watt ratio , only advantage is can put light closer to plants but 400 watt mh isnt that hot either and as long as you have air flow no worries, for nutrients I use general hydro series , cheap and if nasa uses it , you know it's good , don't waste any $ on more expensive stuff because it will do same for more $ , GH Grow ,Micro, Bloom , KoolBloom , and I like seaweed also only like 15$ bottle , Soiless for grow medium , Bcuzz or sunshine 4 , or anything close to that is best imo , air flow and lights, cheap grey or any dark color buckets 2-3$ local hardware store work great also , this is what my rooms are made up of , well I have 3 400w MH's , 6 600's and 1k hps's , 1k will be replaced by 2 600's soon , 600's you can put closer to the plants and better lumen per watt for 600's then 1k's , i used to run 1k's when I was new but changed to 600's and way better yields IMO. Will try to read more of your posts but I have to go work on the room some more . Oh for legal purposes I am also a medical card holder and caregiver in michigan ...
