if i find something interesting, i hit up my shop and ask them to contact the company to request samples. I find that most companies will go out of their way to get sample products to hydro stores instead of an individual going direct to the company itself. Just picked up the full line of
Greenstone nutrients for a test grow fwiw, and they hooked it up! Ive done this multiple times, Black Label,
Technaflora, Myco, BioAg, Beneficial Biologies,
Roots Organics let me test their new B2 formula medium, etc... Especially if you leave credible feed back to the store and company for which you are sampling.
