Semi-hydro is a modern way of growing plants without soil. Instead, plants are grown in an inert medium like LECA (clay balls) or pon, and sit above a small water reservoir.

This reservoir allows the plant to absorb exactly what it needs, when it needs it, reducing the guesswork that comes with traditional watering.

Because there’s no soil, you also get better airflow to the roots, fewer pests, and a more controlled environment when paired with nutrients.

Less guessing. More growing.

Yes! Fertilizer is essential in semi-hydro.

Since there’s no soil, nutrients aren’t naturally available. Use a balanced nutrient solution labeled inorganic or safe for hydroponics (We use GT Foliage Focus) when watering so your plant gets what it needs to grow and thrive.

Some types of pon may already contain slow-release fertilizer, adjust accordingly.

Water only when the reservoir runs low. Keep it filled about ¼ of the way up with nutrient solution (typically 1–2 inches, depending on pot size). Your plant will take what it needs, when it needs it. Avoid letting the reservoir stay completely dry for extended periods.

Most plants handle the switch really well! Some might pout for a week or two, but if you’re gentle with the roots and keep the water level just right, they’ll bounce back and thrive.

Alternative method: Not ready to go straight into LECA? You can transition slowly:

1. Remove your plant from soil
2. Rinse off most of the dirt
3. Place the plant in water with a little GT Foliage Focus
4. Wait 1–2 weeks—soil roots will fall off naturally
5. Once you see healthy white water roots forming, transfer to LECA!

This method is great for plants that are sensitive or if you’re nervous about damaging roots during the switch

 Yes! Just rinse it thoroughly between uses and boil it if you want to sanitize. It lasts for years and cuts down on waste (and fungus gnats!). 

 The white, chalky coating on your LECA is usually mineral or salt buildup. This happens when tap water or fertilizer leaves behind dissolved minerals as the water evaporates.

In small amounts, it’s normal and generally harmless. However, heavy buildup can affect pH levels and make it harder for your plant to absorb nutrients.

To fix it, rinse your LECA thoroughly with distilled or RO water.

To prevent it, use distilled or RO water when possible, flush your LECA monthly, and avoid over-fertilizing.

If the white substance looks fuzzy instead of chalky, it may be mold rather than mineral buildup. If you’re unsure, feel free to reach out with a photo!

If you have climbing plants like Monstera, Pothos, or Philodendron and you want those big leaves we all adore, moss poles can help cut down the time it takes! Moss poles help them grow bigger, more mature leaves and strong aerial roots. When paired with LECA, moss poles provide support without overwatering terrestrial roots.
