whas a clf!

whas a clf i been looking around and i seen it looks like a energy saving lightbulb! lol but its a compact florencent but is it really a energy saving lightbulb?

reason i ask is i have a 'friend' who's growing in a gallon pot soil mix with water on a 18/6 cycle atm untill said 'friend' has enough bucks for his 150watt HPS ballast for his 150watt HPS bulb this is only going to be for another 2-3 weeks maybe and it seems to be growing strong like over night it shows development, i have no fan in there at the mo so the stork is abit slim at the mo, the leaves are quite big about a inch apart and its about a foot tall i dont have a clue what kinda weed it is though lol

any inputs?

its a type of light,do ur homework.

If your wondering what a cfl is and your saving for a ballast what are you using for light?

a spiral energy saving one

thats a CFL or compact fluorescent you just normally get stronger ones and use multiple bulbs
