 Lighting question

i just went and picked up 3 45 watt 2900 lumen's cfl, i could get 4 more for about $50 that would give me a total setup of 7 bulbs 315 watts 20300 lumen's or i could get 1 more cfl and a ballast for my 150 watt sodium light for 90 that gives me 330 watts 25800 lumen's. what does everyone think would be the best way to go? not getting it all, only growing 1-2 plants

The first thing I'd recommend since you brought it up is to get your 150 watt HPS going. CFL's will work if you need them to work for you, but there isn't a lot of light intensity (something adding more bulbs can't improve, beyond simply encouraging more equal light distribution, which is a good thing of course), and what will happen is you'll develop some really nice sucker buds (really good formed bud at your canopy, long stem for a stick underneath). Get the HPS running and then use your CFL's to supplement on the edges, and even on the sides. You could even look into some basic CO2 supplement techniques, like sugar water and yeast, released when the ventilation is stopped to do so, and you'd have a nice little setup to really get the best from those couple of plants.

i actually was setting up a yeast starter for the co2, the more i am reading the more I'm getting worried about the color temperature. i have 8 spots for lights few will be for uvb's and others for cfl's, and have a separate "lamp" for my sodium light. can you help with what i believe to be now my color temperature problem. i don't have any plants other then a hugh tomato plant that didn't give me any damn tomato's this year under my 3 lights. i am testing everything before i get serious. started some bag seeds the other day no sprouts yet, when i get it all set i will spend the cash on something good.

Well, as far as color temperature is concerned, when it comes to CFL's, you have a spectrum for vegetative growth and a spectrum for flowering. The vegetative growth spectrum is usually called "daylight" and has a color temperature around 6500k, and the flowering state is "cool white" and should have a color spectrum around 2700k. Do you know what the color temps are for your bulbs?

I'm not sure exactly but i think they're in the red area, what would that mean for my plant and its vegetative growth?

It would mean that your plant in its vegetative growth stage is primarily looking for blue spectrum light, and you are giving it red spectrum light, which it needs more of in its flowering state. Ultimately, what this would mean is that the plant is going to stretch in an attempt to find more of the light it needs, which isn't preferable with indoor growing, and it will take longer for them to mature, since they aren't getting enough of the light they need to complete its life processes.

update- went out and got my ballast today, ordered 2 85 watt 6500k lights hopefully be here not broken in a week. setup will have 5 lights 2 45 watt 2900 lumen's 3000k lights, 2 85 watt 6500k lights, 1 hps 150 watt light, and this weekend i will be picking up some exo-terra repti glo 10.0 compact desert terrarium lamp for all my plants uva and uvb needs. That should take care of lighting now need vitamins a soil additives.
