I agree and I like how you're looking out for me with that selection what's your take on Jack's 321?
jack's and MC are similar nute types and approaches. MC is a fair bit more cost effective.
the two-part hydro version of MC would probably work better in an auto pot.
i would actually recommend getting some fabric pots and hand watering for a grow or two before firing the autopot up.
it would help you get a feel for the plant, how they grow, and what their needs are like.
