https://www.amazon.com/Spider-Farmer-Dimmable-MeanWell-Spectrum/dp/B07TS82HWB shows 28"x28" footprint for 1 light. @18" it's a 500 umol/s blanket coverge, which is great for a mature vege'ing plant. 2 in a 3x3 might be too much. ~500 would be the minimum you want for bloom, for reference. 12" with 2 in a 3x3 could work -- as long as you don't see fewer trichomes at top as it deveolops... should occur top-down. if not, it's a sign they are evaporating due to heat or too many photons of energy. if you ever see buds below more rip than above, it's very likely your lights are too close regardless of other specs. you're tent size isn't optimal for your footprint in vege, but it can work. you'll just have a hot spot in middle at 24-30" for vege. In bloom it'll be better due to a roughly ~1" strong footprint, but with overlap, you'll have a solid coverage in your tent at 12-16". it'll be weak at front and back, though (or any 2 sides.) line your equipment on one wall, and that takes care of it, lol. offcenter lights where plants are. a rectangle shape is better for you. a 4x2 would kick ass with those lights in bloom, i bet. custom 48x30? get a cheap lux meter for $10. it'll allow you to even out the coverage. if specs are accurate, the lux can even it out just as well as a PPFD meter. anyway, along with their par readings and 28x28 coverage, you can pick a height, then lux meter can help you even it out with spacing/positioning of lights.

mate its perfect ; at this height you shall get perfectly thick bushy plant and dense nugs... just make sure that till the end of flower ; it is atleast 13 to 14 inches away from tops.

Hello.. Hope you are well.. Personally id pull them bk to 36inch if ur seeing problems.. At such early age u got sum pretty powerful lights.. If u see signs of stretch then bring closer in 2inch intervals until she looks to balance out.. Everybody's growing environment is different and recommendations are just set at optimum conditions which many of us do not have unfortunately.. Heat & plant transpiration also has huge effect on growth.. Raising ur light will definitely stop ant signs of heat/light stress.. U want to b 24-36" at veg and ideally 12" away during flowering.. As she gets bigger the lights can get closer(in theory, obviously depending on heat exchanges, strains, etc).. Stay safe n gud luck with ur babies.. 👍🍀

Your right on where you should be.. As they want about 14 inches away in flower.. a good rule is to double it in early veg and start to lower it slowly as they grow to about 19-21 inches. then 14 at the flower switch! cheers and happy growing!
