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

Keep Your Smart Float 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. 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 or modification required.
• Transplant With Plug Attached: Move plants into soil or hydroponic systems with the plug still attached, avoiding bare-rooting or root disturbance.
• 55ct Bag -- One Full Batch: Matches the 55-cell capacity of the Smart Float Grow Tray, so one bag restocks one complete tray.
• Continuous Propagation: Refill bags let you propagate an unlimited number of batches with a single Smart Float Tray.

Frequently Asked Questions

Are these plugs compatible with other propagation trays?

These refill plugs are designed specifically for the Hydrofarm Jump Start Smart Float Grow Tray. They may not fit the cell openings of other standard plug tray formats, so check compatibility before using them in a different brand of tray.

How do I use these plugs in the Smart Float Tray?

Drop each plug directly into its corresponding cell in the Smart Float Tray. Insert a seed or cutting, keep the tray moist, and let the floating insert design maintain the ideal air-to-water ratio for rooting.

When should I transplant from the Smart Float Tray?

Transplant when roots are visible through or below the plug and typically appear white and firm. Move the plant with the plug still attached directly into soil or your hydroponic system at that point.

How many plugs come in the bag?

55 refill plugs are included per bag. That is a complete restocking supply for one 55-cell Smart Float Grow Tray, matching the tray's full cell count.
