Well when I get to 6 total kessils then maybe a spinner costs almost what a light cost. The thing is like a lot of grows I see guys with high end leds and then a bloombooster and I see why. I would be better served getting 2 more kessils and 1 more CLW bloombooster and keep the kessils stationary with both CLW bloomboosters angled in on the outside of a a row of plants moving back and forth on a light mover. That way I get even kessil light across maybe 6-7 plants and 2 CLW bloomboosters moving along both of the outside edges on movers. As of right now that seems to be the heaviest bud on my plant (where the 2 lights mix). I do have 3 weeks to go on my first plant running under kessils so will see what the final weight and smoke is like before a final call but so far blooming lights + bloombooster seems the right direction.
