If you prefer an out of the box, plug-and-grow solution, I’d suggest two SolSheet Xs powered by a single Mean Well HLG-480H driver for your veg space. That would give you up to 600w of dimmable LED over 18 sf, or about 33 w/sf, which is a nice intensity (PPFD) for veg. You’d want to hang the lights at 24", and use 5000K CCT SolStrips for better vegetative development and height management.
For your flower space, two SolSheet Originals run off a single HLG-240H on each side would fill in your “wings” and give you good coverage into your HPS field as well. Our 2700K SolStrips match the HPS spectrum very closely and would work seamlessly with your HPS bulb there.
If you are at all inclined toward IKEA-level assembly, two 36" SolStix Racks with 5 SolStrips each on an HLG-185H driver would also work well in the flower “wing” space, give you more even intensity levels, and save you a few bucks as well.
Please PM me here or at sales@solstrip.com if you’d like a custom plan prepared for your space.
