It's gimmick/hype in my opinion, only viable use I personally see in it is relieving stress. I used to keep it in my grow op for a little while, until the bottle recently exploded from heat.
Only thing i can tell you is that its good for cloning. cuts root formation to less than half percent without it. i put it in my seedling/cloning bubblers just 2 drops per gallon is all u need.
Its comprised of many of the basic vitamens that supply plants with the proper nutrients needed to induce proper beneficial bacteria neccesary for root formation.
Thats all i can say on this.
Nope ive done this without using any kind of rooting supplements. All i was saying is if u follow ur proper cut, scrape and dip ( alot say 30 seconds but ive left them in for longer maybe a minute) and then to medium preferably a peat plug on a heat mat but u can also put them in a simple cup of water as well. Im getting 100 % clone ratios either way. Superthrive has only sped the process.
