Red VS Blue on Mars

17-05-2021: As you might have seen I have added some reflective foil to reduce heat on the water. This helps a lot. Growth is as expected but they are a bit on the bright side. Well yesterday the set EC was raised from 1.3 to 1.6 so probably new leaves will be a bit darker. Also added a bit of Calmag. Still great to see that as soon the roots touch the water the growth is exploding. Well yet 13 days till 12/12 so I am excited to see how big these ladies will be by then. Hoping for a seventh node before that. 18-05-2021: Today I dosed 18ml of H2O2 (50% silver stabilized). I have seen a few algae so if they are gone by tomorrow I keep this dose, if they are not I will give them a shock treatment of 50ml. In this system I don't have to worry about clogging (50mm tubes) but I also believe that if it is not necessary I shouldn't do it. Dosing is advised from the supplier based on tomatoes by the way. 19-05-2021: All survived the H2O2. Today I have added additional 18ml. Just to see what happens. Growth seems a bit faster last night 22-05-2021: Blue is not doing great... I hope they survive. Red is still OK
