All correct except that I use loose rockwool (aka 'floc,' sold in bale-sized bags) in the pots. My pots are common, 8" diameter x 8" tall black plastic pots (the black colour does block some light from roots, but high-intensity light will pass right through some plastics despite being coloured black), $1 each at Kmart.

Rockwool holds a lot of water and need only be flooded 1x/day. If you fill the pots with expanded clay pellets, you'll need to flood perhaps 3-4x/day during lights on.

I'm not a fan of expanded clay; it's expensive, heavy and if you drop a handful of it, you will chase it all over the room. It might be re-usable, but not without cleaning and sterilising the stuff, a major pain in the ass all by itself.

great stuff Al, just one more question though, how early do you start trimming the lower third of your plants?

I do a couple of passes on branch trimming, once in wk 2 and again in wk 3.

Yeah, Man, I snip the small lower branches about Day 15.
