How to Use Peat in Hydroponics

Many options are available when choosing a growing media for your plants, and they vary widely in effectiveness and cost. One of the most readily available and least expensive growing media is the peat pellet. Peat pellets are compressed discs of peat encased in a biodegradable mesh, and are available in any garden or home improvement store. Peat does not compete with more exotic materials such as rockwool in terms of its ability to hold moisture, it is much less expensive and easier to find for the novice hydroponic gardener.

Things You'll Need

• 1 compressed peat pellet per plant
• Watering tray
• Water
• Seeds

Instructions

Using Peat Growing Media in Hydroponics

1. Set out the peat pellets in a watering tray and generously soak the pellets with water. They will swell to about five times their compressed size.

2. Place one or two seeds in each peat pellet and gently cover with the loosened peat.

3. Keep the peat pellets moist until the seeds begin to germinate.

4. When you begin to see roots emerging from the peat pellets, carefully transfer the peat pellet to the plant tray in your hydroponic system.

Tips & Warnings

• You can also use loose peat, or a peat and vermiculite mixture, as the growth media in your hydroponics system.
