ppl need to realise that this isnt an alternative to other hydro setups its an alternative to soil on a budget.
so, instead of just digging up dirt and putting it in the bucket with a heap of holes in the bottom, you just do this and get better results than the soil, you also get to play with and learn about hydroponics during the grow.
after doing a grow or two like this youll be prepared for stepping up to the more advanced systems.
great post GraF
whats an alternative for perlite/vermiculite that can be had for nothing?
