If your in a cab I would suggest using the CFLS to get you started,,, Cuz temps are gonna be a concern when starting. Espically if this is your first grow.

Seedlings and small sprouts like light but not intesnse heat from a HPS. CFLS work well cuz you can get them really close compared to a HPS at this Starting crucial stage of your seedling or sprout.

rember you can always use Cfls and HPS together.

If it were me I would use the Cfls to start the seeds and after about 3 to 4 weeks I would add the Hps then at week 5 or 6 get ready to flower and use Cfls and HPS as long as Heat permits. if you only get one at a time

Use Cfls Veg hps flower.

My 2 cents... I use all CFLS and get good results. I have to in my cab because of the Heat. Search My name or look for

CFL Grow Cab Log I update often it should be easy to find.
