I've used it for the last few grows and it works a treat.
Suitable for hydroponics and liquid feeding.
You mix 100g with 1 litre lukewarm water.
Dosage is 1 or 2ml per litre.
2.4 kg is £26.50. That's enough for 12 litres.
Grown using said PK
Its only a naturally occurring PGR that occurs in the plant anyhow, its in lots of boosts like Green Planets > massive, Canna Boost and a few Advanced Nutrients boosts come to mind that use it but many others do too. Its the synthetic man made type that are nasty and a no no, i think those are made for and used mainly in flowering game (Chelsea flower show) shit like that pops in my head, well that's how i see it anyhow. Theirs a few different PGR`s used in weed game that are safe to use, but in my head gibberellins which is used for seed gemination or in boosts or for making fem beans and triacontanol are the 2 used lots in weed game. Summink to steer clear of though in my book are the gibberellins if your clueless, cus too much of that you may find yourself growing a shemale typo plant, but triacontanol is solid to use as far as im concerned.
