Just admit want grow kit you can get whether it's from Spider Farmer, Mars Hydro, AC Infinity, or viparspectra or any others will probably do just fine. We've reached close to peak efficiency with LED lights with very little room to improve so now lights are just trying to be bigger and brighter and stronger. Most ppl don't even know what to do with 1600 PAR readings. With that being said, just base it in how many plants you want to grow and how much space you have to dedicate to growing? How high do you want or can afford your electric bill to be?
I'm going to be getting a Spider Farmer tent because they're one of the few that have a tent that's under 63 inches tall in a 2x4 configuration. I don't want to remove the light bar that I installed so SF has the perfect size I need although I would have preferred an AC Infinity tent just because I'm going to be using the AC Infinity 4" inline fan, their T3 humidifier, 69 Pro controller (comes with the fan) and the clip on oscillating fans from them. The lights will be SF 2000. I've been using those for 2 years and I love them and I think they'll get even better performance in a 2x4 tent.
There's plenty good products out there. Just about want configuration will do. As long as you have some good genetics, then everything else will be smooth sailing
