The ”double sized” version of that light - the Spider Farmer SF-2000 and Viparspectra XS2000 are both on sale on Amazon right now for like $ 229. The Viparspectra has a slightly better PPFD spread than the Spider Farmer. I have 2 of the spider farmer sf2000 and 2 of the smaller sf1000. They work great but they don’t cover a large footprint. Expect to effectively cover about 2’x2’ for veg, and about 1.5’ x1.5’ for strong flowering, for each “1000” panel. You can always start with one and add more as you go - they “daisy chain” together. I’m happy enough with my results for the price, but there’s better out there. I use the equivalent of one panel per plant, and it’s not hard to pull 6 oz per plant with some training, more with the right genetics. The SF2000 covers 2 plants for me, if they’re well trained. Take advantage of your reflective walls, and start in the corner. Everyone is pushing the bar style lights right now, and they’re awesome, but they cost twice as much to start. I like to be able to start with one panel, and as they outgrow the space, just fire up another one. It also keeps the use-hours lower by using one or 2 smaller lights, instead of running a huge expensive light and dimming it. Cost and efficiency are big factors for us as we are just growing for personal medicine, and not cash cropping.
