A quick view on the progress of our fresh lemongrass being trialled in two simple hydroponic systems; both in a polytunnel that has no electrical supply.
One is a very simple ‘pot culture’ system where the plants are in a soil medium with a capillary wick which dangles down into a reservoir containing the nutrient solution.
When the sun shines, our solar powered pump circulates the nutrient solution from the reservoir to the top of the clay balls in which the lemongrass plants are sitting. There is no other medium around the roots, just the clay balls.
Both systems are performing very well and a nice fresh Thai curry is very much anticipated soon!
