Del, You've inspired me with all of the knowledge, thank you. I'm one of the paranoids, so it'll take me a while to post pics, but here's a description of my 12/12 from seed perpetual:
Grow room:
1 Meter deep x .8 M wide x 1.5 M tall (it's easier to measure metric.)
Planters:
2 x 45 gallon tubs, each having 8 plants, 4 flowering 4 maturing
8 seedling/sprouting cups in a humidity dome
Soil:
Home made, 4 parts enriched desert soil, 1 part sand, 1 part perlite, 1 part moss. The mix drains nicely, flushes quickly, yet maintains enough moisture. The soil is as close to the rich mountain soil I used to grow in, outside of Espanola.
Seeds: Afghan Indica (Landrace) - I'm just setting up, in the future I'll be adding more variety, and switching to feminized seed (I'm losing 1/3 - 1/2 of my seedlings to the Y chromosome, that sucks)
Lots of CFL lighting:
Overhead: 4x65W 65K, 4x23W 65K, 4x23 27K - I'll be adding 2 UVB (10K) bulbs, and 2 65W 27K bulbs when I can afford it. Current wattage: 444
Soil Level: (each bin) 1 23W 65K, 1 23w 27K, 1x13 65K (mini tube, trouble-light style CFL) Current wattage: 59 per bin
My current total wattage is 562, electrical cost is 22 monthly increase
I'm using some general purpose nutes ( 2-2-3 ratio, I don't remember the brand, my mother bought it for me.) Water is filtered, 1 Tbsp per gallon unsulfered molasses, 1 Tsp magnesium sulphate. I water twice weekly, once with just water, once with nutes+
Air circulation is courtesy of a dual circulation fan (2 30CM fans in a single housing)
Temp stays around 82-88 during the day (lights on) and drops to 70 at night. Humidity in the "room" is 30-45% depending on length of time since last watering.
I'm 2 weeks in, I started out 18/6 to 12/12, but, the lighting was an issue. The landrace is vegging nicely under 12/12, the random sativa bag-seed that I threw in for shits and giggles is also blooming quite nicely.
I'm pretty sure the bins will only hold up for 3 or 4 cycles, by then I'll be more set to build my grow better. Better lights, ventilation, 4 times the area, 1 gallon pots in bins vs. a "garden grow"
