This hobby is just so much fun with the evo 4-80. The node spacing is easy to control. Depending on how you want it, I had a distance of 30-40cm from the plant to the LED, and it resulted in excellent growth.
Very good as always, good mixing ratio with perlite. Had good nutrient supply for the first 3 weeks, pH 6.5, water retention, and root ventilation were very well provided. Soil is important.
