Witch watt, watch, wonders
10 watts of florsents is 10 watts no more no less
CPF are a worthless as most of the bulbs serface is not going down , and with a 100% reflective serface its only 96% at best.
Thats why you full service , mag. ballast. The electronic ballast eat bulbs and have a short 1/2 life
Using full service , mag. ballast 4 ft shop light are the beat way to go
Use the full service bulbs and ballast , with cool white till at the time to bloom.
Remember to trim to the point of 1/2 the total heigh at bloom. Note some strains will go 3 times the grow heigth.
Now yeild roughly 1000 grams net over 2 months from a 1000 watt bulb is .5 grams. The best I have seen is .6 grams .
Something to note, that was a scrog system with dirt.
Next , use all florsents in you house, turn off all non running things , by unpluging them. TV,VCR, printers all have a instant on this uses more power.
Power company want to sell you power , if you pay for it.
ONE thing to look out for is a polling meter , its the new electronic digital display. They can tell when you use , how much power , and when you turned it on.
If you grow look normal , act normal and fly low. AND never tell anybody you grow, NO exceptions , None , Nada , nope. The ass you save will be your owne
