I Don't think it would be very good crop if you did that. If you could just throw some compost in the soil every once in awhile that would be better.
it is possible but you'll end up with very loose buds if there is any way to get some ferts its deffinately more than worth it
yes!this is how i grew mine no ferts totally organic growing at my grandmas house lol,i dont even water it and its a very strong plant with good buds(atleast it had them before i broke the top cola)but i still have popcorn buds :]
