10-05-2021: I am counting today as day One for Veg. Planning to hold them on 18/6 till the 20th of may (ten days) and then switch. Not sure if I will stress them a bit or not, time will tell. Yesterday was hot (26ΛC) here so all values have shifted a bit. Won't be a problem as soon as they are on 12/12. Do you notice the lines (air/water) changing position on heat :) Didn't even notice that at first. Also pretty sure I need a more powerful chiller at the moment but will first make an attempt to replace the gas.
13-05-2021: Today I will be replacing my chiller. It doesn't keep up and the temperature of 28ΛC is a bit too much. For the rest.. All great
15-05-2021: Added some paper sheets to reduce heat. Seem to work so today I'll go to hardware store and buy something to make a more permanent solution.... I have added some reflective foil to cover the boxes
@Ze1ro, Very true. And to be honest I like to experiment so it isn't a bad thing at all something goes wrong. I have learned that you can spray H2O2 (12%) directly on the roots to remove mold. Yes it does slow the plant down but it will be capable to survive.
