I’m all for adding more SolStrips, but with an HLG-185H-24 you probably are already pulling around 200w, or 25w/sf. That’s close to the 30-40w/sf range that is ideal for bloom spaces, and great for veg. You likely already have all the light you need to harvest very nice product over 80% of your space. Only the corners will likely fall out of optimum intensity range.
Don’t rip up your light. Augment it. If you really want to add 5 more strips, you should be able to fit 2 SolSheet X’s side by side. The X’s are 26" x 19". So two should fit fine, with a little bulge, positioned with the 26" sides running along the 2 ft width of the tent.
Better I think would be to get a SolSheet Original. 150w (what you need to get you into the 30-40w/sf range), and half the size of the X - 18"x13". Turned on its side next to your X, that’s 26" + 13"= 39 inches long x 19" wide for both lights. Nice fit and room left to have ventilation space around all sides of each light.
