It is a very good question.this is probably a dumb Q but is it bad if you use miracle grow? or just grow it natural? need responses!
I would start my clone out in something smaller until the roots begin to crowd the pot. Maybe a large cup then after a while transfer it to something larger. The five gallon paint bucket is a good way to end up when you are going for the final grow but you may want to grow it in smaller increments until it gets larger. I use a 5 gallon for 4-6' plants.How about this, I get a clone form a grower and I live in a apartment with just enough space for a five gallon paint bucket with soil in it. Now what ?
