I have 2 under current style systems one is a 50 gal and one is 75. Im running 4 Cheese Dogs, 1 Doc's OG, and a Sour Boggle. Pictured below is the 6 site veg under a t5. I usually veg for 2 months while the flower room, holding 6, is in use. Im really pumped about this run. Ive heard alot of good things from respected growers about this product. Mills is a 2 part Base and has 3 additives, Start- R, C4, and PK. Thats it. It averages to about 1 dollar per gal. Im going to be using a cal-mag by All Day Orgainics called MR. Mucha-Stash (Michigan Made). So there it is, I hope it all goes well. Im also going from 1 Gavita 1000 to 2 Gavitas and 6 Hortilux 1000 watt Blue's. This should be cool. Mills is available at Garden Doctor, 1st in Michigan.
