Answers about CFL, HPS, How Much Light...
Sorry to wake up an old thread but I wanted to just ask about supplemental lighting in the flowering stage to up the number of lumens psf I'm currently going to be around the 3000 lumens psf mark using 2700k CFL's. If I was to add additional CFL's to my setup to increase the amount of light, should I just add more 2700k bulbs when flowering or is it beneficial to use 5600k bulbs as well. Which would be most effective?

Answers about CFL, HPS, How Much Light...
I'm doing my very first grow-box for 1 or 2 plants. Now that I've designed the box and ventilation am thinking about lighting. I was thinking of 150w HPS light but they seem to be slightly out of my price-range. I know that CFL are much cheaper and that they make bigger than 40w bulbs. For 1-2 plants what is an optimal amount? How many fixtures and how many bulbs? To get close to a 150w HPS?

I use 9- 40watt CFl's at the 2700 range, for Veg, and Flower. My space is 72" L X 32" W X 48" H. Everything seems to work fairly good. I get ounce or two from each plant. Do I need more light in that space? Growing 3 plants at a time.

I recently found 44 watt CFL lamps in Staples for under $5. That's a deal! They were $8 in Walmart.
I am using (4) T5HO 54 watt tubes for supplemental lighting during bloom for nine plants in 5 gallon pails. I have 'grow' and 'bloom' spectrum lamps. At the moment I'm using two of each. I think maybe a full spectrum has an advantage over one or the other.

I would say that something is not adding up as you are only getting 2 ounces per plant, scrog seem to work quite nicely for cfl setups to produce big time

I got some 6500K for my next Veg. I hope that will make a difference when I go into flower. Maybe my plants will be bigger, so I can get bigger buds. I see on the pro vido, that he used, HPS and MH in the flowering stage. So I now will have 4-6500K and 5-2700K in my flowering cycle. I will let you know if this produce any more. After 14 days of drying, my ww x bb only weight 32 grams. This was my first try indoors. I'm working on my second now. Some Pineapple and WW X BB and some Green Love Potion. Good luck, and happy growing.
