I've been hearing that CFLs will end up costing more for replacing bulbs and that they don't give enough heat. But I've seen the buds on this board and I think they are wrong about the heat.

But how many grows will I be able to do if I order 1 200Watt CFL 5000K, 1 200Watt CFL 2700K, and I have a reflective hood and LOTS of reflection in my box.

Will this method be worth it?

then way a see it, hps and mh lights are better buys for your money and more powerful. the only advantage to using cfls is they can be placed literally right on the plant. it will be more expensive to replace the cfls. and they wont save much energy either, because youl likely end up running the same amount of watts with either. the hps and mh lights also give you alot more lumens per watt, so id say mh hps is the way to go.

running watts on a cfl are lower than light output ^ so the math your going does not add up

o no it adds up perfectly when you consider the lumen output.

i use 300w 2700k cfls and i dont think they use as much power as a 300w hps or mh or maybe im not understanding what you mean

lol yes but was is a 300w light or a 300w equivalent? big difference. my point is simple, 400w of cfl light and 400w of hps light cost the same, it is 400w either way. but the 400w hps light is pushing alot more light then that of 400w cfl

I don't need anything close to 400W I'm only guna do 2 plants.

it was an example. get a 250 or a 150 if you want samller.

The other thing though is that I have to get a ballast. How much more does that make it?

Also, I've got a cardboard grow box in my closet. is it guna get too hot in there with HPS?
