I bought the substrate off ebay. It's a mixture of poo, straw and some grass. It was called a Boom Block. Up until the 2nd round of bigguns it was in a filtered bag, in vitro style. I have been told humidity and moisture in general are a huge deal. Next round im going with Brown Rice Flour and I think it was Vermiculite. The tek I plan to go with is the PF Tek. It seems to be the simplest. What are you using?
Also,and unrelated, I don't recommend buying Vander lights. Not that most of you would but you never know what'll happen. The light I have doesnt seem to be strong enough to push full buds out of my auto. Either that or something else is wrong. A flowering auto should perform well under a spectrum leaning to the bloom side right? My humidity is low, 30-40%. I just can't keep it up there with the exhaust running and it gets to hot without exhaust. How loud are those booster fans? I bet one of them would actually work just fine.
If you had to choose a budget LED what would you guys use? I've been looking at the King LED 1500w and the Bestva 1500w. Same price on amazon. But I wonder if it would be better to go with MArs Hydro for about double the price?
