Jump Start Smart Float Grow Tray Refill Plugs, bag of 55

Restock Plugs for the Smart Float System, Bag of 55

A propagation tray is only as reusable as its supply of fresh plugs, and buying a whole new tray just to start another batch wastes both money and a perfectly good floating insert and reservoir. This bag of 55 refill plugs is sized specifically for the Jump Start Smart Float Grow Tray, dropping directly into the existing insert's cells for another full propagation cycle.

Because the plug stays attached to the plant at transplant time, this refill bag keeps an ongoing rotation of seedlings or cuttings moving through the same Smart Float tray without buying replacement hardware.

Key Features & Benefits

• Bag of 55 Refill Plugs — matches the cell count of the Smart Float Grow Tray.
• Drop-In Design — plugs fit directly into the existing tray's cells.
• Plug Stays Attached at Transplant — move a rooted plant to soil or hydroponics without disturbing the root ball.
• Supports Repeat Propagation — reuse the same floating tray and insert for an ongoing rotation.

Who Should Use These Refill Plugs

These refill plugs fit growers who already own a Jump Start Smart Float Grow Tray and want to restock it for another round of propagation instead of purchasing an entirely new tray and insert.

About Jump Start

Jump Start, a Hydrofarm brand, sells refill plugs sized to its Smart Float Grow Tray, so growers can keep the same floating insert and reservoir in ongoing use across multiple propagation cycles.

Frequently Asked Questions

How many plugs come in this bag?

This bag includes 55 plugs, matching the cell count of the Smart Float Grow Tray. That's enough to fully restock the tray for one complete propagation cycle.

What tray are these plugs designed for?

They're sized specifically for the Jump Start Smart Float Grow Tray's 55-cell floating insert. Using them with a different tray isn't guaranteed to fit the cell spacing.

Does the plug stay with the plant when I transplant it?

Yes, at transplant the plant moves out of the tray with the plug still attached to its root ball. That keeps the root system undisturbed during the move into soil or a hydroponic system.

How do I use these plugs in the tray?

Drop each plug directly into an empty cell in the Smart Float insert, and the tray's floating design will keep it evenly moist along with the rest of the cells. No extra soaking or preparation is needed before dropping them in.

Can I keep reusing the same Smart Float tray?

Yes, restocking with a bag of refill plugs after each cycle lets one Smart Float tray support an ongoing rotation of new plants. There's no need to replace the tray or floating insert between batches.
