I got some Dyna-Gro Foliage Pro and Flower for the outdoor crop this year.... It's so much easier for my partner to make up some nutes with this stuff, than for us to fertigate with my custom formula... So far the results have been great.... We are re-using peat based media from my indoor, along with a blend of dry humic acid and water polymer crystals.... Its pretty amazing stuff.... lengthens your watering schedule by a day or 2 depending on if it rained or not... I'm surprised more outdoor growers haven't utilized water polymer crystals in their soil....
I'm pretty happy with the Dyna-Gro gear its not too expensive compared to the others, and while you can buy a bunch of different products, it really isn't necessary for good ganja
