If you looking for a booster but not a pk type boost, well lots contain similar things, vitamins, carbs, amino acids , hormones and some even zymes, but not all contain the super dooper natural occuring PGR hormone tricacontanol like canna boost, green planets massive and i know advanced do a few pure organic additives/boosts containing it and i`m pretty sure BB & OD contain it too, but i`m not totally sure about that bit tbh, their maybe more as well i not really looked, but it`s this that bigs up the buds on the plant more so than owt else in it in these type of boosts and so takes these boosts to another level and to me these are all premium tyope boosts that makers charge premuim prices for except one, so it`s a no brainer really . You can buy Triacontanol powder pretty cheap but it`s about getting doses rigjht although iv`e looked into it b4 or lets say breezed through it and it`s pretty straight forward stuff and its all their on web to show you how to and how not too, you just gotta be carefull fucking around with PGR`s but Triacontanol is on the ok list and organic and naturally occuring in the plant as are all naturally occuring organic PGR`s , it`s the man made synthetic ones which are more for flowers, ornamentles and pesticides, so these are the ones which you should be weary of and probably steer clear of, although they are used in the weed industry by shady fekkers as it`s not a regulated industry like the food chain is, certain synthetic ones well they are known to out perform Tricacontanol which is why they are used by lets say cash croppers (cus we can) and even sneaked into certain products so you gotta be carefull, theirs a list somewhere on the web but i can`t find it, but Dutch Master Super Bud, Rox & Flower Dragon come to mind as dodgey boosts containing man made hormones from way back although i have read they have been revamped and smartened up since, but iv`e never read nothing official saying so only in threads on grow forums. Best way to avoid using any of these dodgey boosts is simply to look who makes them on the bottle and like fuck will it tell you if it does contain them like it does on all ferts, additives and boosts in big daft lettering on the front usually, like advanced, vitalink, gro-tec and canna`s and all the rest do, tell you why shall i, tis cus sneaky fucking peeps that do make them well are known big fert makers taking piss in an unregulated industry out to make more dosh than they do already, greedy cunts they are. But yes that`s what i was told avoid products if the manufactures name isn`t on the bottle anywhere even in small writing, when i first started growing by a good guy who knew his shit, cus it won`t be their on any of these shady products, their was a big storm about it a few years back, but well, fuck it i`m ranting totally off topic lol, i just thought i`d point it out whilst it was stuck in my nut. I could go on but it`s a bit vague now, tis just this popped in my head whilst we on about hormones and stuff. All that said not all synthetic are bad for your health, depending how you see it, some are bad to the enviroment and some both, i suppose that it depends which ones are used and if you willing to take that chance without looking into it a bit more.
