I use a 1000 watt hps and put 25 plants under it. Basically 5x5, 1 plant per sq ft. I use pro mix as my medium. I was using a miracle grow type product for fertilizer but had terrible results. Severe magnesium deficiencies. Thats why Im looking to go with a top of the line fertilizer, I am hoping to avoid those types of issues. I hear you about only being able to talk on here, too many theives out there to be able to trust anyone. Alright well Im gonna give Big bud a try, I have never used a bloom booster before, so I'm excited. Thanks man, any questions regarding anything (I'm good with bug control, mites, thrips, etc...) feel free to leave me PM's or whatever.
