Hi Rasta,
I am using this method next grow, I bought the compost, two five gallon buckets for 5 bucks
BLACK TEA COMPOST
This is our top of the line Class 1 Compost that is rich in water absorbing organic matter, while being low in salts. We also formulate this compost to have a neutral/low PH to help counteract and remediate Colorado’s high alkaline soils. With these natural advantages, this Black Tea Compost helps in with seed germination when used as topdressing. We make this special compost by combining enzyme rich animal feed, baby poultry bird bedding, and high-quality horse bedding that contains flailed wood shavings, alfalfa, and straw. After all these ingredients have been mixed, composted, and cured we end up with premium compost diverse in healthy micro-live.
I have a question however, are those plants sitting right on concrete floor? I heard thats not good.
