I am testing the Danish brand Big Plant Science; Powerhouse, Micropower, Stimulus (this is SAR activating) and Bud Explotion. I compare it with Adv. Nutr. Sensi, Bud Ignitor, Big Bud and Overdrive.
@XxxAuto is also testing Big.
I use Big on all new plants now.
For the FastBuds Green Crack I feed 2 plants Big and 1 plant Sensi. Not very scientific. Two plants with each is ok for hobby use, but a minimum of 3, better 5 or 6, and repeatitions are necessary if one want to do some simple stats.
Www.bigplantscience.com need to be translated to English asap. Its feeding schedules are based on hardness of water. A very interesting approach.
