    fox farm soil trio nutrients American and Canadian feeding schedule Canadians use half as much products why ?

    I think (could be wrong) the "limited products" refers to the fact some of their stuff just isn't sold up north (like Big Bloom). Granted, it's still a really... useless... response either way.

    fox farm soil trio nutrients American and Canadian feeding schedule Canadians use half as much products why ?

    So I notice that at least some of the ingredient labels are different between CA and US. For example, CA's Ocean Forest doesn't mention bat guano. Presumably that's why Canada doesn't have "Big Bloom", as that is basically guano and earthworm casing tea. I'm guessing as such, the formulations...

    Ridiculously hard water as CalMag supplement?

    So, got bored and was doing some math earlier and I came to realize something. GH's CaliMagic supplement is by volume, 5% calcium, 1.5% magnesium, and at their recommended dosage of 1mL per liter, you end up with a solution of 50ppm-Ca and 15ppm-Mg. My tap water is ludicrously hard, over 600ppm...

    Will GH PH Down & Up kill off bennies in rhizosphere in DWC?

Citrate (from citric acid), ascorbate (from vitamin c), acetate (from vinegar), all possible food sources for bacteria and fungi. It's one reason why using organic acids (like...

    Opinions on exhale Co2 bags

    Thankfully, if all you want is the CO2, then no need to worry about the fruiting environment, you can just leave them in the jars to happily churn that rye into burps.

    Opinions on exhale Co2 bags

    I love Exhale's bags in concept.... but for the price of a single bag I can make the equivalent of dozens of them with my InstantPot, some mason jars, bit of cloth tape, and a couple bucks worth of rye grain. Granted it takes a bit of practice to be able to do things cleanly, but even a "failed"...
