Hi , i m gonna build a growbox , the height will be 110 cm , feet square will be 1.3, so my question is ,will be a hps 100 w or 70 w propriet for it or should i go with CFL 125?
 
Any Hps is better than a CFL. thre only problem i see is heat issues if you have a small air cooled hood with proper ventilation you could pull it off. post some pictures of where you are thinking about growing.
 
Never have used anything that small i use 1000's. now that i think about it i think your area is too small 7 inches is a start to disapate the heat but realistically if you are looking to grow some weed that will get you high your 70w light is not enough you will get about a 8th for all your time/money/effort you are going to put in this. and the heat problem will drive you mad.

for your grow i would look into the CFL thread

I never knew they had less than 400w HPS haha, that's crazy :P I don't think it'd be worth it, especially if you'd have to buy a ballast as well. When it comes to those size grows, CFL is the way to go, like dakushman said.
