The sf 3000 for 3x3 will crush your grows find the the right height and percentage on dimmer. I have 2 tent a 3x3 mars hydro and 2x4 ac infinity. I think the MH is better quality and the led in my 2x4 is the MH TSw 2000 for 2x4 tent I’ve haven’t bought from dispo in months but when I’m low or dry and curing I’ll hit the dispo but once I smoke my own it like night and day from that hydro trash. NJ sells. Yes I’m gonna buy the Migro led for my 2x4 cause I turn it into a living soil bed tent I made a pvc and filter fabric pot that is the size of tent and man I’m on year3 of running plant in same soil just cover crop and some top dressing here and there. I even transplant right next to old stump from last grow and the new roots eat it all up. The terps are better the buds are stronger only difference is yields. I don’t yield as much as when I was salt and petroleum feeding my medicine. I’ll take a few grams less and have quality knowing that I’m the only o e who touched my herb is a great feeling. ESPECIALLY when u crush a grow and take cuts.
