Adding one or two of the Height Extenders to the Complete Mushroom Grow Tray extends the usefulness as fruits mature. The vented sides help you maintain the desired humidity and temperature for optimum growing. Each of the extenders adds a further 4” in height under the dome of the propagator allowing for continued control of your grows from start to finish. The sides have a positive lip that engages the base and each subsequent height extender for a positive fit as they are added in sequence. The lid likewise fits in a similar fashion which permits you to lift it from the extenders to access growth from above without disturbing the climate of the grow. The height extenders can be disassembled when not in use for compact storage. This pack includes 8 security clips, allowing all the pieces to attach together so the entire lid can be removed as a single piece.
These Extender Packs are also great for those using the tray for seed starting and indoor herb, greens, or microgreens gardening.
Available for both Medium and Large Complete Mushroom Grow Tray systems. Complete Mushroom Grow Trays must be purchased separately.
