I was wondering if you can continue to use cfl's during flowering or if you have to switch to a mh or hps?

You'd need to get the right color spectrum though, warm white lights in the color spec of 2700k are the ones you're going to be looking for if you decide to stick with the cfl's.

I laugh now at people using cfls T5 T8 for flowering/ growing, I was talking to a guy today and he was bragging about a Qp off of 9 plants veg'd for 2months i laughed at him and said you can get that off of 4 plants under a HID light and veg for a month. Then he started asking about the dirt i was using and nutes and temp blah blah blah, so i told him get the right light and stop wasting your time

Ok so then a second question, I have a HPS bulb but no ballast. Is a ballast completely necessary to use a HPS bulb?

Yeah. Investment will be about $250 for both ballast and bulb. Check out specialty-lights.com I got my ballast an HPS and an MH bulb for 280.00 and the shipping was free.

If you live in a city, you might be able to snag one on Craigslist. I grabbed a 400W HPS Ballast, bulb, and reflector for $100 in my town. When I searched, there were 4 for sale in my area, and I live in a fairly small city. It could be worth a look.

lol, maybe. If you could have some way of knowing what colour temp the colour filtered light would be.

green is a gauranteed plant killer fo sho. I did this as a science experiment in a science class. ther results varied with the substances that I used to change the color of the light. Im guessing now as i am older its actually the color spectrum that makes the difference. check out this thread that pretty much died.

I never orded anything to try because I rearanged my op so that i didnt need side lighting.

yeah they r not cheap. did alot of research on these. you have to have the right ballast for the bulb and that's where it gets expensive. 400 watts is good enough for about 16 plants in 5 gallon buckets.

Ya so I went out and spent the money today. I built a sort of enclosure out of plywood (because ive been worried about neighbors seeing it in my back yard) mounted my 400w HPS inside w/ my new ballast. Bought an outdoor timer and set it to 12/12. and Its all hope from there. I've noticed my plant developing alot more trics and becoming more smelly and sticy (F**king awsome) and im pretty sure its still got like 2-3 weeks left before harvest thanks for all of the input ill post some updated pics tommorow.
