Hmm, well all of those mentioned are "goals" so as to speak lol. I'm a newer-ish grower so you'll have to pardon my ignorance.What are your goals? There are many ways to skin a cat.
Hardness? Growth? Terps and flavonoids?
I've done a lot of research on these forums about how to grow plants, what to add to them, etc. and a lot of that research has indicated (from others) that 'bud hardeners' 'bloom boosters' etc. are unnecessary products that produce negligible, if otherwise unnoticeable results. Therefore I found it interesting that my local hydro shop is making the claim that the seaweed product hardens the bud.
At days end though, I'm trying to create a fantastic product, not so interested in size/yield of the bud. I'm planning to invest in a bigger & better space once I get accustomed to the basics here.
