additive

Hello all let me first say thanks again to everyone here! Without the help and info from the people here I wouldn't be where am. So I have been using nutrients from a company called rx green solutions, and they recently came out with some additives as well. I have noticed no nutrient...

i have started a new cloning techniue. a regular black tray, with lots of bubbles, under rafts. first time, all went great. this time, clones dying, and slimy bottoms. what is the best additive, to keep the wanna be roots, stems, happy, and encourage grouth? thanks.
