Hi guys this will be my first grow and i want it to be a pretty small plant (Stealth grow) but not sure how this is done. Can i use bagseed? that all i can get i dont care if its a small yield.
Yes, you can use bagseed, BUT. . .
The cheap stuff is usually Mexican grown, and those plants are better for outdoor growing. . .they'll be relatively tall plants that take a long time to flower.
If you use a strain designed for growing indoors, specifically one bred to stay small yet give good yield, you'll probably have better results.
No, do NOT grow under a halogen light. Halogen lamps don't put out a good spectrum for growing plants.
The minimum light you could get away with is probably one 23 watt 2700K fluorescent bulb, but you'll have much better results if you use more light. Try multiple compact fluorescents, or alternatively larger ones (eg 45, 55 watts). Depending on your budget and what kind of space you're trying to fill, a small high-pressure sodium lamp (say 70 or 150 watts) will be more efficient, giving better yields for the same space/heat signature.
The main things to consider when growing small are:
a. What kind of SPACE do you have to fill. That's really the first and most important thing, because your growing space will dictate your pot size/shape, growing method, type of ideal plants, and necessary lights.
b. Budget (in order: Lights, timer, seeds, soil, cooling, odor control, nutrients). Budget does not have to be a lot *IF* you know what you're doing.
Make sure that whatever container/chamber you grow in, that its:
a. Light tight. . .leaking light out will give you away.
b. Ventilated appropriately. . .you'll need to cool hot lights, and ensure that your plants get fresh air.
c. Quiet (noisy fans aren't good), and
d. Odor-controlled. . .flowering plants can give off a heck of a scent, even really small ones.
