1st Try Aeroponic Cookies Gelato

Hey Guys, whats up?! Welcome to my first grow ever... Decided to start my growing career on an aeroponic high pressure watering system and LED lights. Here's the setup: Build myself my own Growbox out of MDF and coated it with pond liner, sealed it all up with Tape so there are no airgaps. On top of that layer I put Diamant Silver Eco EASYGROW foil for the right reflection of light, all sealed up with diamond aluminum tape. Box 120x100x285cm ; 2 Compartments ; Top has a height of 36 cm. Top has the exhaust ventilation System build in, which is connected to the grow cabin through a hole in the ceiling. A 125mm hose is connected to the Active carbon filter installed under the ceiling in the grow room. -Aero grow garland Table M by aeroponik systems -Prima Klima Active Carbon Filter Industrie 460 m³/h ø125mm -Prima Klima Rohrventilator Whisperblower EC Drehzahregler 0-100% 450m³/h ø125mm -Sanlight Evo Series 4-120 250 W for Veg&Flower -Secret Jardin Cosmorrow Veg LED 20W for Seedling Stage -2 Fans 20 W one oscillating -Humidifier 4L Tank -Bluelab Guardian PH/EC Monitor Day 1-7 13.01.22 - 19.01.22 Seeds in a glas of water for 1 day; next day put them in 2 layers of kitchen paper towels, keep them nice and moist PH: 6 EC: 1,1 [BETTER 0,4- 0,6] my tap water is really fucked up.
