About how much light y’all think I’ll need, got 3 120w led bar lights that put out 270 ppf/ea 4000k spectrum would would adding one or two more similarly specced lights be sufficient? Gonna have a 6in exhaust going directly outside covered with a screened vent cap. I’d like to use as little wattage as possible so if there’s something you think would do better with less throw down a link.
Ideally I want to keep it under 500w
You’ve got about 25 sq feet there with a weird footprint. Those 3 lights probably won’t be enough. I veg around 500-600 PPF. 270 would be fine for seedlings and the first couple of weeks.
Yeah weird dimensions are kinda by design, it’s as big as I’m gonna be able to build in my kitchen and still have room for cooking, and appliances😅. That’s 270 ppf each on the 120s. I’ve flowered a 2x4 with them, but yeah I still think that’s a bit low for the area. Think one more should do alright I guess.
If you use the whole space you will want more than 500 watts. With decent LEDs try to get around 25 watts per square foot of grow space.
Here is a decent read on choosing a light to get the watts per square foot you need for a great grow. You can get by with less but the grow will be less.

Yeah I kinda already understand growlight basics and how to grow with leds, asking a more specific question about minimal lighting for a veg room that will be holding a few moms and seedlings/clones- roughly week 4 of veg. Think I got it figured now though. Gonna add another cheap qb 100-150w then in the winter run 2 + a 315cmh.
Construction starts payday!🥲
