My first grow Zkittlez/Cocofresh

I finally received the new 1000w Spider farmer new light, the AC infinity extractor and the humidifier, I’m loving them and also the plants. I moved the light to 18 inches same intensity 50%, they are grown very fast, I’m really excited. I also did water changes to all of them and I’m now using 4 ML of hydrogen instead of 3 ML. I ordered Root drip of FF but looks like they are in back ordered, will see when it arrives.
