How To Repot Houseplants with "Terraponics" Growing


Repotting houseplants with our "terraponic method" makes the transition from soil easy because the roots are not disturbed.

What is terraponics?




1. Soak pebbles for several hours (or overnight) in KLN Rooting Solution.




2. Choose a hydroponic grow pot that is slightly larger than existing  grow pot. For table top plants should be at least 1/2"- 1" space between root ball and grow pot on all sides - and at least 1" space at bottom of pot. Floor plants 2-3" space on all sides and at bottom.




3. Fill new pot with about 1" of pebbles on bottom (this should be increased for larger plants).




4. Position plant on top of pebbles. Add fresh pebbles around side of root ball.



5. Pack down pebbles. Be aggressive - use a tool if necessary



6. Add more pebbles at top until root ball is covered.



7. Insert water gauge. 



8. Put plant in outer pot.





Watering New Plant Growing in Terraponics


Plant care for "terraponic" plants is basically the same as growing in hydroponics - 

except for one major difference!

cut back on the water.

A "terraponic" plant needs less water because air doesn't circulate through the soil root ball. That soil root ball needs to dryout between watering too - so you'll need to be careful with the water at first.


1. Using the water gauge as a handle, lift plant (and inner pot) out of outer container. Take plant to sink. 

2. Run water (or a KLN Solution) through the pebbles.

3. Return plant to outer pot with no standing water at the base. Any water that drains through after watering and sits at the bottom is okay.

4' Repeat once a week for 3-4 weeks. 

5. After initial period, start watering to 1/4 on gauge. Wait until bottom of outer pot is dry before rewatering.

With terraponics, the weight of the plant is a good way to judge when it's time to water.


When the water gauge reads "Min", it doesn't mean it's time to rewater. That soil root ball buried down inside the pot is still wet - and it needs to dryout so those roots get air too.

When the water gauge reads empty, lift the plant. If it feels heavy (like the pot is full of bricks), there's still water in the root ball and you'll need to wait a couple of days - sometimes up to a week - before watering. 

If the plant feels light (like the pot is full of feathers), then it's time to rewater.


Just like hydroponics, these plants should dry out in 2 weeks. If there's still water in the reservoir after 2 weeks - or the plant feels heavy - dump out any remaining water and force a dry period of several days before rewatering.

Then rewater, applying a less. Watering to only 1/4 on the gauge is common for most terraponic plants. 

Over time, terraponic plants start acting like hydroponic plants because their roots have grown out into the LECA pebbles.

Hydroponic roots mean a stronger, more durable plant. After plant adapts you don't need to be nearly as careful with watering.
