Grow Light Central helped get me setup with exactly what I wanted! No run arounds or bs. Quickest shipping I’ve seen! Like, actually 2-day shipping, and no long wait time after ordering! Everything arrived packaged discreetly, well protected, and in perfect condition. The machine itself assembled easily & works great! It does a better job than I expected on most material. The Quantanium Tumbler and Variable Speed Control motor kit are worth the added cost. Slower speed for dry material is almost essential for the best quality flower preservation, and the Quantanium Tumbler makes for easier cleanups less frequently. There is some material that won’t go through it well. Anything smaller than the slots in the tumbler or loose material will get pulled into the leaf collection system. If anything does get pulled through, it won’t be wasted as the bag system is an awesome addition that will sift your trim, automatically. Cleanup isn’t a breeze, but it still takes less total time than I would have spent cleaning scissors trimming the same amount of material! Overall, I think it’s a well crafted & engineered machine that will pay for itself in no time. My only regret is not contacting Grow Light Central sooner!!
