 Yes! LECA is just a support medium—it holds your plant up and gives moisture, but has zero nutrients. That’s why we use GT Foliage Focus—it's pH-buffered, easy to use, and gives your plant everything it needs to grow strong.

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

Only when the water in the reservoir gets low. You want the reservoir to be filled about 1/4 of the way up. Your plant will pull up exactly what it needs, when it needs it.  Try not to let the reservoir stay completely dry for extended periods, as that can stress the plant. 

 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!). 

 Pretty much, yes! It's especially great for aroids and tropicals, but we've seen everything from succulents to ferns do well in it—with the right care. 

 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—yes! Moss poles help them grow bigger, mature leaves and strong aerial roots. When paired with LECA, moss poles provide support without overwatering terrestrial roots.
