I tried Jacks Hydroponic and Calcinit on a few runs, messed around with it for about 6 months. Finished smoke wasn't up to standards and didn't burn well. Buds didn't swell. Definitely not as easy to mix either as it needs multiple parts to be complete. I think it's made for lettuce? basil? Saved a few bucks, lost a few pounds.... You get out what you put in right?
