You need to do a LOT more reading before you begin, no offense. First of all, where did you get the fact that the plants need 80,000 lumens? The sun gives off 10,000 lumens sq/ft. Also, your math in your original post is horribly wrong. Just follow this math a little. You will be using 9 bulbs for vegging, and will undoubtedly need to buy more for flowering, since they use different spectrums. So here is some math:
- 9 bulbs running at 26 watts each = 234 watts
- 9 bulbs costs around $3.25 + 3 power strips which cost $6 each + the adapters which cost say $1.50 each = $60.75 This of course is before you HAVE to buy even more bulbs for flowering, running at 2700K instead of 6500k. So you can probably add another 30-40 dollars on top of this as well as increase the watts used to run the whole setup.
- 9 bulbs running at 1600 lumens each = 14400 lumens
- Say your space is 4 sq ft, which is a 2ft by 2ft space, you will be running around 3600 lumens/sq ft, which is under the minimum of 5000 lumens a square ft, but would still work.
OR
Buy 1 250w HPS which would cost around $135 shipped to you, runs 33,000 lumens and uses around the same amount of energy that you would be using with your "efficient" CFL's. You would be running 8250 lumens/sq ft, which would increase your yields a SHIT TON over CFLs and make the buds dense.
You probably wont decide to go with the HPS, even though its a MUCH better idea, as CFL's are a waste of time unless you are trying to grow in a teacup, but seriously, before you dive in, you need to do a TON more reading. |
