look into Growers Choice ROI-E420, Spider Farmer SE5000m, and MIGRO Aray 3
The Spider is a lot of light in a small tent. For me, that would be the light of choice.
I can't find a PPFD map for the Growers Choice so that takes it off the table.
Migro lights are, across the board, not high powered lights. All of his offerings use drivers that are lower wattage than other manufacturers. That allows him to market a light at a significantly lower price point but there's a reason for that - the lower powered driver means that there's less light. Is there enough light? Yes but there's a reason why the price tag is lower.
In this case, it's a 250 watt driver for $270. The spectrum is heavily weight at the blue end with a tiny bump at 660. Meh.
The Spider uses a 480 watt driver and it will generate a significantly higher amount of light than the Migro. There's more red in the spectrum, as well, which is a good way to deliver a lot of photons to the canopy. The price, with a coupon, is very competitive vs the Migro but light output is a lot higher. Add in the fact that they're a sponsor here (and that they have been for a while) makes it seem like a pretty good bet.
