It wasnt too great, and that article I recently linked had me thinking it's not such a great or quality company. Apparently it's not even from the neitherlands, but from an unscroupulous guy down unda. Try dyna-gro, I stake my reputation on that it will be the best thing you ever tried. Check out homebrewers threads "dyna-gro vs Conoisseur" and others.. Super simple, cheap, concentrated, and you don't need anything but the bottle of gro and the bottle of flower, some ph, silica (do get the silica cuz it really helps stabilize the ph) and some mag-pro if you use r.o water. If you'r not going organic, then dyna is some fool proof stuff man. Homebrewer's threads talk about a good nute regimen to use with it as well. I have been using the stuff since the 90's, and couldnt believe how insane other nutes are nowadays. They wont push the stuff at the hydro shop, cuz it's old school, and you dont need to buy much if you use it, so its not so great for their sales, plus alot of new generation growers figure it's old technology or something, but honestly, it's used by alot of commercial food ops, and they don't mess around with novelty items. If you don;t thanki me for the advice later, I'd be damned surprised...
