Bests & Worsts Reviews from Amazon

I purchased this dome to start seeds in the winter, and was attracted by the heating pad as well as the taller dome. The design of having the seedling starter cell tray sit on top of the waterproof tray is the first mistake, as the dome collects the water from the humidity inside (as it should) but then runs down the sides of the dome and OUT OF THE HOT HOUSE! I ended up with the heating mat sitting in a puddle of water, and dry plants. The point of the adjustable openings on top is to control the humidity (nice idea) but this unit loses all of it's moisture within 48 hours, and I have to continue to refill it. The peat pellets dry out quickly, wasting my seeds, time, effort and care. I've trimmed the edges of the cell tray so that there is a small gap between it and the side of the waterproof tray, so hopefully the water will run down the sides of the dome and INTO the tray, so the humidity stays inside. So far, the best part of this whole package is the heating mat. Simply - a hot house designed to maintain warmth and humidity only maintains warmth, it loses all humidity very quickly, and is far inferior a design to the simple, low priced lower domed trays I had used in the past. I am considering adding a flange of packing tape on the inside of the bottom edge of the dome to direct the condensation back into the tray rather than onto the floor.
