I paided $500 for a 2x2x5 grow tent that came with a LED light , but you will need to get a few other items to get the right control in the grow tent . So I say start bargain shopping and like the guy said , buy all your items first for your tent , and once you get your accessories , than you can start your grow , now you said you plan on growing in a garage right , that can be challenging in the hot season , if you don’t have cool air to pull inside the tent . Cannabis grows better in about 72-78 degrees , so you will have to supplement cold air some how , but I’ve have about 6 grows behind me , just starting number 7 , but that lil tent has produced some very , very good bud and my biggest yield yet has been about 4.5 ounces from a blueberry and 3.9 from a Amnesia Haze . Now this grow I’m shooting for about 10 ounces , which take time to learn on how to max out your grow space . But by this time next year , you won’t have to buy no more bud , you can definitely be growing your own even on low budget . But if you look around the forum , there are guys growing in 5 gallon buckets they engineered themselves and producing around an ounce and half if not 2 ounces with auto flowers .
