new indoor grower need help with CFL

I wanted to know if this full spectrum CFL was going to be enough for Vegi/Flowering. the buy at the store says it is full spectrum and its 102 watt 500 watts output it is for veg/flowering. it has 7000 lumens. and it is 5k full spectrum. Will this be good enough for growing 1-3 plants? This guy who runs the store also says this one light can do 12-20 healthy plants. The CFL is 13 inches long BTW.

I allready ordered two CFL's one for veg and another for Flowering but if I can use just the one I may buy it to and just use it and my other 2 bulbs along with it in the right stages.

Any input would be apprieciated.

For best results, I'd recommend 6500k for veg and 2700k for flower. Everything else in between is unneccesary for what we need. If it was me, i'd pass on the 5000k bulbs.

As posted above the 5000k spectrum will be nothing but a waste of energy. Also I think that bulb is only good enough to grow 1-2 plants only, not 13-20.

but the 5k 105 watt cfl will grow at least 1-3 plants then? Thats all I am really looking for.

A 105 watt CFL is a good start, but you'll need more light than that. What we're trying to tell you is don't buy bulbs in that middle color temperature range (color temp measured in kelvins), around 5k. That is the most useless spectrum of light for a plant to live on. Go for 6500k for veg and 2700k for flower, you'll have much better growth. Good luck to ya

yes id use it for veg and get a better one for flower. target has 42 watt 2700k bulbs 6 of these will do wonders for your yeilds

That bulb is a waste of money, find something that size in 2700k warm white
