That stuff needs soil bacteria to decompose it into usable fertilizer and is designed to supplement soil grows. If you need organic, General Hydroponics has a line of nutrients that will work. If you need dry powder and organic, I have no idea.

If you don't need organic, Masterblend's 3-part formula is your best bet as it's super cheap and effective. If you want a 1-part, Maxigrow is good.

You can upscale this with a tote and net pots. https://www.amazon.com/dp/B00NQANQAC/ref=cm_sw_r_cp_apa_glt_fabc_Q8WVGNS1KPT8C45H8G1V for nutes.
