Budget Propagator Overview This tray is a cost effective propagation tray with a clear dome of good height for cuttings. Initially it was thought these “budget” propagators would appear flimsy and crackly, intended perhaps for a single use. In fact, these propagators are well made and sturdy. The only thing that could be described as “budget” is the price. The size at approximately 35 x 21 x 12 cm is very useful and will comfortably hold a 24 cube tray of Rockwool or Root Riot. The quality is good enough to allow re-use many times. Highly recommended.
