Just started. Late in a ILGM White Widow grow. Up to that point had been using salt based fertilizer. I was about a month into flower using Flower Fuel and others, salt based. Then I made the switch. As I could afford the product I started with Medusas Magic (MM) and then a couple weeks later Herculean Harvest (HH) and the girls fattened their buds like never before.
Of course I have them under a decent light, a SpiderFarmer 4000 at 80% power 6" away from cola tops. This light certainly has helped in what I must say is my best effort in 3 years of growing. But the nutes have made a substantial difference. I clipped a couple popcorn buds from down low and couldnt believe the flavor, just incredible.
I wont be using anything else. Except that because these products (it might just be HH that does this.... been sampling the girls ; ) ) bind with the salts, in fact the HH is recommended to finish a plant off before harvest in place of flushing, you could just skip the flushing and feed the girls to the end.
In short, Im sold
