BUT FIRST A REQUEST FOR HELP
The plastic object in background is a double walled plastic water holder. It has lots of 3-4 cm tubes you fill with water and it not only keeps frost off tomato seedlings it also moderates the micro climate and helps them grow fast fast fast. Hence red tomatoes in Beaufort before xmas.
We have three. they are at least a decade old. They are beginning to deteriorate. We have done heaps of searching and unfortunately have never seen any to buy and are looking for a substitute.
Any ideas?
