I hear ya, however I had enough searching and reading about that stuff so I'll pass on a link the place where I found a lot in one place about it... but theres info here on RIU as well as everywhere else, just read up on it before putting it in you ladies dude, the horror stories of burns are what turned me off of the stuff before I started catching the banned in cali threads as well as the more experienced guys would recommend getting LOTS of water through the plants before harvest when using any of HCO's products and getting lots of water through screams chem to me, thats just a reason for me not to use it. I know it sounds kinda stupid, but I'm going for the healthiest herb possible which is why I started trying to grow organically/veganically...(havent mastered the vegan part yet but I'm 100% organic at the moment).
Edit: I'll PM you the link.
Theres a thread by someone named chargersfan in that list, its about using the HCO products in hydro however he compiled a ton of info about them.
I know the bottles say derived from sea kelp, but I use kelp in a few different ways and none of it slows or stops vertical growth, that may be the main ingredient but it isnt the only one, that I am pretty sure of.
I definitely dont want to tell you not to use something but I'll be honest with you, as I said, I have a full bottle of that shit and I really dont care what I had to do to deal with the stretch, I'll figure something out by tying/cutting/flipping earlier/using MH for the first 2 weeks of 12/12...something.... so I wont have to put that shit in my plants. Trust me, I know how good the shit works there is no doubt about that, if it wasnt fucked up in some way everyone would be using it. Are you kidding me, cutting off up to 2 weeks of bloom as well as halts vertical growth completely..... it would be getting a lot more use and press than it is and it has been around for awhile.
