Here's a winner,
Grow you out something from a strain you really like (or for that matter, what you have on hand).
Get a 150w (uses like 60w power?) equivalent CFL for your momma and the clones you make. Veg the clones until about 8 inches high.
Flower in a 2x2 x 4-5 foot space under a 250w HPS.
put 1 or 2 of your 8 inch or so clones into one of two small tubs.
4 weeks later start the other tub.
you get to harvest every 4 wks about 1.5 to 2.5 ounces using B.C. products.
Reservoir is about 3 gals each.
Some months are leaner than others, but if you know you'll harvest again in under a month, it makes it worth it.
And make sure you make a tincture of your sugar leaves that you crop during pruning. EverClear is the poop. So is using Mason jars for your tinc.

DUH! get a good enough air pump to aerate both tubs through wands that are like 18" long. Watch your PH! and replace your fluids every week to ten days. Take the excess and water your veg garden :-)
