man... i just started growing yesterday and i see all these things about HPS and MH MID and all this crap.. i have no idea what any of it means. i have 2 25" 33 Watt Grow lamps, Actual grow lamps, i asked the dude at Canadian tire what i should use to grow some plants and he lead me to these. their light output is 470 lumens each. my grow box is 3 ft deep, 3 ft high, and 2 ft wide and the whole intereor is tin foil. i lie to you not it gets hot up in that shit. and REALLY bright. is this sufficient for my 2 plants? (their germinating right now, and arent even in the box yet.)
