Hydrofarm Jump Start Smart Float Grow Tray Refill Plugs - 55ct

Hydrofarm Jump Start Smart Float Grow Tray Refill Plugs - 55ct - Keep Your Propagation Going Batch After Batch

Hydrofarm Jump Start Smart Float Refill Plugs are the replacement plug supply for the Smart Float Grow Tray, allowing you to run continuous propagation batches without purchasing a new tray setup each cycle. Once seeds have germinated or cuttings have rooted in the Smart Float Tray, transport each plant with the plug still attached directly into your preferred hydroponic system or soil growing media - roots are never disturbed, and the plug transitions with the plant. Each plug drops directly into its space in the Smart Float Tray. This 55-plug bag provides a complete fresh set for one full batch.

Key Features & Benefits

• Designed for the Smart Float Grow Tray: Plugs are sized and shaped to drop directly into the Smart Float Tray cells - no cutting, trimming, or modification required.
• Transplant with Plug Attached: Move plants into soil or hydroponic systems with the plug still attached to the cutting or seedling - no bare-rooting, no root disturbance at transplant time.
• 55ct Bag - One Full Batch: 55 plugs per bag matches the 55-cell capacity of the Smart Float Grow Tray - one bag restocks one complete tray.
• Continuous Propagation: Refill bags let you propagate an unlimited number of batches with a single Smart Float Tray, maximizing the value of the tray investment.
