“Now I save 20% on fertilizer because of the TOOB. My plants are more symmetrical, and I have 15-20% more yield. The weight of the plant has also increased by 30%. I only fill up my O2 tank about once a week. The TOOB is incredible. I’ll never grow again without it! If someday I have to go work for someone else or get another job, the first thing I would say is, ‘Get a TOOB.’ It’s made all the difference for my crop.”
