m0useanswered grow question 4 hours ago garbage light. not designed for growing weed or plats despite what it says, more or less something that cost very little and the person reselling them is making bank on it.
Put away some money and wait for a sale on a real grow light. Some of the entry level lights from the manufactures who make the big ass pro lights are descent. Spiderfarmer, Marz, viperspectra, medic grow all good options. I have a medic grows mini sun2 and I like them a lot. they are a strong basic light with minimal features that do what I want. Only downside to them IMO is that that only dim in 20% increments and it starts at 40% so if you want to go down to 10-20% its not possible without a controller.
Everything I said above is for LED's. if you looking into HID or florescent lighting there are other options and some are likely less money but they are not nearly as efficient.
Stay away from most stuff on amazon, some other lights off of alliexpress/alibaba are ok, gotta know how to check the specs and see if they are good or garbage.
