if youre looking for lights for seedlings, anything t5 or small led lightbulbs will do. once you hit veg your best bet is a cheap chinese or mid brand with samsung lm301b or lm301h. tons on amazon, ac inifnity has a 100w for under $100. but surely a viparspectra, meiju etc can do it just as well. you can flower with those too.
also, i compiled a bunch of diy projects for lights, soil and other shit here if you want to take a look.
