I have been using canna for 5 years now.....ever since it has been in my area....i drive an hour away just to get the shit so that should tell ya something.....i also noticed that their formula for the nutes is great use their directions....until you feel comfortable then expieriment......i tend to increase what they say and have had awesome results so far...some people say that its not worth the money but i differ with that.....i also use both boosters in deep water culter and coco.....check out their website or their phamplets..very informative they know their shit thats for sure...i also only use the aqua series for both my deep water culture buckets and my coco...has anyone else done this before....coco seems to have no prob with the hydro nutes......
