Bests & Worsts Reviews from Amazon

The tray is a standard 10x20" and has a matching dome with some humidity control vents. The mat is full-sized and sits under the tray warming the whole assembly slightly. Not included are the grow media "plugs" or the seedling starting trays. These are considered consumables. There is a sample of Clonex Rooting Gel which being a sample is enough for a handful of clones or seeds. The Clonex Rooting Gel is most highly recommended. The dome is of medium thickness, I've seen them much thinner but there are premium brands that are thicker. If you buy a pair of these the lights can be run in either left to right, front to back on the trays sitting side-by-side. There is a daisy-chain electrical cable included to link the two lights together if used this way. The water tight bottom tray is heavy enough to get years of use from. The T5 light has a reflector to focus all the light down into the tray.The light draws 17 watts of power and the mat draws another 23 watts.
