That was me with the OD light dep bed ! It wasn't an above ground bed ,as much as it was just plants in pots, placed in a light dep grow box  (4x8). Remember the one I built out of straw bales ? If you have privacy it's a great way to grow, an early crop. Veggum  for a 3-4 weeks at 18/6, check your daylight photoperiod, and move OD a few days before 12/12, it's around March 15th in Missouri. The biggest hassle, is having to pull the light dep tarp on EVERY NIGHT ! After it got dark, I always pulled it back off, that way it was off in the AM. Cold weather can also be a prob . Later
