i have been following this grow for ages and ages...
again well done noreason...
as a suggestion you could put down a shallow layer of clay balls in the tray....they can work well to keep the roots cool
cheers
Thanks buddy
I was taking into account to add some clay pebbles in the trays…it should work, but there is one problem, the clay pebbles themselves. Every run I have to buy and carry between 30 and 45 liters of clay for every tray, no one should see and pebbles are pretty heavy and obviously I have to trash the old ones. So I guess it's not the best option only for this fact, however many thanks for the suggestion, I always take 'em into account.
At now I choose to use a spreader mat, the classic one for NFT. Will see this summer if it can work as I want. More pics soon
