The trays are and mix of normal 1020 and 1020 Heavy Duty/Extra Strength (heavy duty ones are great). None of those have holes so they can be flooded. The cell trays are for 36 plants (2x2x3" cells.) The domes are 7 inches tall for 1020 trays. They are all nested inside 1020 daisy trays to give them extra strength, when I pick them up, and for later when they are outside and I water them with the hose and water needs to flow through. Most of the items I got from other people who bought plants from the local greenhouse, but all the domes came from online suppliers.
