How To Use Rapid Rooter Plugs To Germinate Seeds

Rapid Rooter Plugs and TrayI’ve tried several different methods of germinating seeds for my hydroponic gardens. My preferred method is using rapid rooter plugs made by General Hydroponics. They are easy to use, have a great germination success rate and can be used in all of my different types of systems.

What Are Rapid Rooter Plugs Made Of?

Rapid Rooter cubes are derived from composted materials. I’ve bought some derived from peat moss and some from tree bark. The plugs are formed in a way that creates optimal water to air ratio which promotes excellent root growth.

How Do You Use Rapid Rooter To Germinate Seeds?

The first thing to do is soak the Rapid Rooter plugs in distilled water. Some people soak them up to 24 hours; I typically soak them for about an hour and have had no issues.

After soaking, place the plugs in into the grow tray.

Place a few seeds in the center hole of each plug. Using more than 1 seed increases the chances of successful germination for each plug.

If using a tray made for rapid rooter plugs then you need to fill the tray with about a quarter-inch of water to keep the plugs moist. The holes in the bottom of where the plug goes to allow the plugs to wick up moisture.

Cover the tray with a dome to keep in moisture and warmth. If you don’t have a done you can cover the tray with saran wrap.

If the type of seeds you want to germinate require a warmer environment, then use a seedling heat mat underneath the tray to maintain a warmer temperature.

When seeds sprout, place the grow tray under a low-intensity light for seedlings.

Keep Rapid Rooter Plugs moist by adding water to the tray.

When roots appear out of the plugs, they’re ready to be transplanted. They can be transplanted into pretty much any grow medium and in any hydroponic system.

    Do the seeds in the rapid rooter get light right away? 24 hours like veg stage?

    DO you need to seal the hole above the seed or is it okay to leave it open?

    • Good question. Covering the hole may be necessary if you can not germinate seeds in dark place. It’s especially helpful when germinating tricky seeds where some may sprout before others. That way you can have the light on for those that are sprouting while still allowing the other seeds time to sprout.
