If you can get a 400 watt hps light or 600 then youd be goldern. 600 watt digital ballast with mh and hps bulb with air cooled tube shipped on ebay for like $160 then you could do few different ways quadruple or more your yield in less time. Cost maybe $20 a month to run a 400 watter
Thank you for your input, but...
The first time I grew CFL was about thirty years ago. I was working in an office and I planted a seed in with another potted plant. I noticed the seedling grew towards the light. Eureka! I thought. And I started growing in closets with cheap flourecent light fixtures with bag seed..
I never figured out how to bud a plant. I would pick and smoke the leaves as they got old. I would pinch and smoke the flowers every third tier. I'd have these bonzi looking plants lasting six to nine months giving me a couple doobies every day or so. I was happy.
Now, you youngsters have CFLs and the internets and seed breeders, and still you want more? I just want to grow enough to last a couple three years or so, without burning down the house. I got my medical MJ permit (cough cough) good for one year. The CFLs I use will eventually be put to use in the house when I'm done growing. I've done it before.
