How To Repot Houseplants with Terraponics Method

Concerned about shocking your plant during the transition from soil to hydroponics? 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 (clear water works too).


2. Choose a hydroponic grow pot that is slightly larger than existing  grow pot. (for table top plants 1"-2" larger. Floor plants at least 2"-3" larger and 2"-3" taller.


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

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

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

8. Add more pebbles at top 

9. Insert water gauge and put plant in outer pot.



Plant Care Growing in Terraponics

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

but there's one major difference!

cut back on the water.

A "terraponic" plant needs less water because air doesn't circulate through the soil root ball and it holds moisture longer than a regular hydroponic plant would. Those soil roots need air too, so we recommend waiting several days after the water gauge reads empty before rewatering.



Tips for Watering New Terraponic Plant


Watering plants growing in terraponics is simple. Pour water (or nutrient solution) over the pebbles - the water gauge will tell you how much.


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.

That means you'll need to allow more time for the roots to dryout before rewatwering.

A good way to determine when it's time to rewater is by judging the  weight of the plant after the gauge reads "Min".

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 water, 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. 



That means a stronger, more durable plant. You won't need to be nearly as careful with watering.
