winter will get cold. its hot as shit here right now though. im using a closet as well. I'd much rather use two of those long ass tubes since I have a lamp that can house two of those.well before you run out and buy a light tell us how big you grow space is? do you have plenty of space over your plants to raise and lower a high output light? mine is in my bedroom closet its a 400w hps which puts out plenty of heat. but i also live in the south 90 deg in the summer ect. will you be living in a place where winter is cold?all this stuff facters into what kind and the wattage of the light for heat.
I have like 8 cfl's in me setup right now. but I feel like I need the room the be hotter.
is there a bulb, a strong one, that will provide a different spectrum for me and put out some heat to increase the temp of my room?
preferably one that I can just go grab from home depot or lowes or some shit like that.
A regular incandescent bulb produces plenty of heatI was joking about going out and getting a 1000w light to generate heat (Although it definitely will).
You can just acquire an HPS now and it will work in veg and flower. I have on many occasions just used HPS for the entire grow.
