my plants are loving it even tho I only planned for four plants. Didn’t have it in my heart to toss the fifth one and squeezed her in. She seems to be thanking me for it.That should work great. Mars also makes the TSL 2000 which also great for 2x4. I have SP 3000 light for 2x4 and double up for 4x4. Love them, but heat needs dealt with.some of their newer light use the bridge lux LEDs, which run a little cooler.
