I'm not talking about initial cost (although you can get t5s way cheaper than that), but what you put out for electricity every single month (and the extra heat that CFLs put out). The CFLs put out about 62 lumens per watt, the T5s put out about 92 lumens per watt. So every single month, your electricity bill will be 30% higher with CFLs than it would be with T5s (or HPS). Twelve 23W CFLs use 276 watts and emit 18,000 lumens and a lot of heat. A 4' 4 bulb T5 uses 216W and emits 20,000 lumens. You simply get more light for less money.
No I know exactly what you mean THG dont get me wrong. However I dont understand your math for the CFL the 23W 2700K Spectrum CFLs right at Lows, run 2100 lumens a piece. Thats over 25,000 Lumens not 18.
Now granted the 6500K run only 1900, but I will be mixing up to a 75/25 ratio reds/blues, and will be building up to even using that many bulbs. I mean right now I have 5 babies in 1 - 10" pot they are only about a week and are only using 2 - 23W bulbs. I will only be adding maybe 2 more and that should hold for another couple weesk because the size of the plants I can get them all in a much smaller space to have to light. This to me is the CFL benefit. Only having to supply it with just what it needs space wise. Acting as loss-prevention in the case of, well, anything.
If I go buy one of these T5 systems. They will draw all wattage from the get go regardless of if not the bulbs are using it. Thats what the ballast does. Plus this whole damn house still has 60W In-cans. These will be going very soon, which should balance out the cost of lighting to begin with. 200-300 watts a month isnt that much, and then you consider a 23W actual watt pushes the same light of a 60W In-can. So basically Im gonna cut overall light use wattage by almost a third. Then tack on 200-300 Watts again. In this house it will balance. Again works for the exact situation.
In regards to CFL I can purchase them over the cylce of the grow and still have some gas money.
I will just go on record saying I know that CFL isnt the most economical, but I never claimed it was, I calimed it is good for reasons, and then some more reasons, thats all.
Oh and BTW THG I wasnt being demeaning when I quoted pricing, I will admit I didnt go as far as one would think. I googled checked some popular sites, popular brands, etc. Didnt check the EB or CL admittedly.
Thank you for the link though Hamster and THG I actually think I may get a small HPS to aid in flowering. Couldnt hurt.
