5 gal pots start with clay balls, then some organicare pure, fresh worm castings, and stuff, then roots organic soil couple inches repeat organicare pure layer, more roots. Then right before I transplant anything into this pot I put down some great white. Then transplant, back fill with just roots and a little extra perlite.. On the top I top dress a little with more fresh worm castings, then a mulch layer (more clay balls). Then spike the pot with 2 veg spikes and 2 flower spikes. (For the unaware this method is the rev's and he has a book all about it, true living organics)
Next watering I add a little more great white. This is all done during the vegetative stage.
I use only rainwater or sometimes distilled water from the store.
It could be a "water only grow" although the use of mellow teas is pretty helpful. The spikes are keep as they contain a shit ton of much needed stuff, and without them your plants would suck growing in this manner.
Go organic! Organic smokes better, tastes better, or at least I think so and so do a lot of others!
There's lots of ways to grow this is just how I do it, right now anyways
