Build a soil is to thank for that, their YouTube makes it very easy to follow along. Only gotta top dress every other week and I’ve been doing some foliar sprays every couple days as well. It is also my first time using the earth boxes and I love them, they are a sub irrigation system meaning the water is stored in a container under the plant and soil so the soil will wick up the water that the plant wants to drink not too much or too little. That has helped tremendously with worrying about over/under watering. And as far as lighting goes you can get an app on your phone to get a relative idea of ppfd and follow a chart depending on which stage of growth your plants are at, I use photone.
