Melon Candy (NFT)

Hello everyone ! Everything is going well, I've soaked the small rockwool only 1 time since the last update, I transplant them into the bigger rockwool the last week end, when I saw several roots under. I've stop covering them since I put them in big rockwool, humidity was too high and the rockwool would never dry. The plants looks OK, but the leafs are light green so I add more nutrient this time. Meanwhile, I'm cleaning my NFT system ( 2 GT205 20L capacity ) I meticulously washed them with bleach, (tank, cover, pump, etc ... ) and now I'm running the whole system with tap water with PH at 5.5 and high concentration of H2O2, I'll add H2O2 again after 2 days I'll let it run a few days ( until I transfert the plant into ) in order to completely clean ( and sanitize ) the system. See you next week !
