Looking good, 4 of those would fill that space and maximize yield. They could be 4 different strains/phenos though

Wait I'm stupid this ruler goes to 18 in so about an 18 to 24in canopy

That's what my intention was/is for run #2 if I can hold off the plants in veg long enough for the NL to finish. I have 4 Barney's seedlings that are different strains but all indica doiminant to help with managing the canopy...........Looking good, 4 of those would fill that space and maximize yield.

oh man so excited with my 315w results. last run i only pulled 1/2lb, but it was my first and there is a learning curve to this growing thing. this run i had 10x2gal clones and one 5 gallon from seed. i weighed my first plant that was dried last night after 5 days hanging. and got 40g. it was even on the smaller side compared to a few in there still hanging. i burped the jar this morning and it is not damp inside ( i know i should get a small RH meter, just doing it by feel atm). i did add a blurple light in there for about half the flower time until it got too warm this summer, but still I am loving the size and smell of these plants on the 315w. This is going to be an awesome harvest.

I am kicking around the idea of adding 2 more sun system 315's.
would it be more efficient to run 3x 3x3 tents
or one 4x 8 with the 3 315's in it?
three 3x3 tents is 27sq feet
one 4x8 = 32 sq feet.
the perks of running three separate tents would be alternating light cycles and be able to run perptually and always be harvesting.
the perks of a 4x8 tent would be larger area to work with and possible overlapping of light making more usable space.
let me know what everyone thinks. i probably will not change anything till fall.

Run a 4x8 put 4 plants under each light every 3 weeks now you have a perpetual in 1 room its easier to run 1 exhaust fan an carbon filter

Yeah that is the way im leaning. i did like the idea of spacing out the power. i think the best results will be had in the 4x8

cross over lighting in a 4x8 will make it so much more effective. It is my plan to run three of these 315 fixtures on one side of my 8x8 in fall. Plus one large filter and fan is quieter IMO.
Glad i found this thread, I'll be buying the sun system lec in two weeks along with a tent. I'm leaning towards a 4x4 just to have more wiggle room, I'll be flowering no more than 4 plants at a time but I've read that these lights are ideal in a 3x3 tent. What do you guys think, I've been debating this for a while and can't make up my mind. Anyone using one of these in anything bigger than a 3x3.
What kind of footprint will this light cover effectively without losing too much intensity around the perimeter.

My 3x3 is slightly over sized @ 39"x39" and it's good. I would imagine if I was pressed for an answer that over 3.5x3.5 it would start to drop off a lot towards the outside areas. I do not know if in a 4x4 (2) 315 would fit, maybe bare bulbs hung vertically? I would prefer two of these over one of the 630's myself to have the adjust ability, but check this thread out:

you could always veg in the 4x4, then when flowering add a few t5s low kelvin.

Have you ran the 630w fixture? I have two of them about to purchase a 3rd. IMO it is similar to having 2 × 600w vs 1k

No I have not ran one as it would be overkill for my spaces. But I run different strains simultaneously and I'm sure most do as well, so having the same watts in two separate fixtures gives you adjust ability for different strains that you won't get running just one.

I'm coming up to 3 weeks with 5x 3gal stretched to 42x42" now. I have a little cross over on one end from some COBs running another batch beside the LEC but the other end is building bud just as well. Not seeing any issues with coverage If I stretch beyond 3x3' I put them to 24" above canopy (normally 20-22" above canopy in a 3x3') and they cover the larger footprint well..
I think the ideal tent with a single unit is 1M x 1M which is basically 40x40" like the tent @Evil-Mobo mentioned above. But in a room taking advantage of the bleed-over between the units works better. I'd go with the 4x8 room and multiple 315's in that config.
Here's the 42"x42"x32"H I'm running right now, not seeing any coverage issues. 4x 3gal different F2 phenos of Blue Ripper (JTR x Blueberry) and 1x 3gal Harlequin in that footprint @day 20.
Cheers

3×3 is what they advertise. I have two of these and plan on buying another ballast from advanced lighting, much cheaper than the sun system fixtures. Always keep a backup bulb I've ordered two that didn't fire out of the box
Currently finishing a plant with a 4k bulb about to enter week 9, she keeps pushing new growth..
