It's an organic grow in Coots mix. (1 part peat, 1 part perlite, 1 part castings with neam seed meal, kelp meal, and crab meal for nutes)
This is its 3rd cycle I think. It's hard to keep track because I have 4 Earthboxes that I bought at various times. This is a cutting of 'Girl Crush' (by Mendicino Twenty20) I took from my last grow when I flipped lights.
I added 1/4 cup of Seabird Guano 2 weeks before flipping lights to flower and worm castings and fulvic acid the day I flipped lights.
It has a 3-gallon water reservoir that it goes through every other day and it was dry this morning.
Edited to add: I also used 4 cups of mineral mix from BuildASoil for calcium and trace minerals. I gave it some sprouted corn, barley and mustard seeds that I ground up in my coffee grinder when I started the cutting for the aminos.
