The Cream Caramel had a nice long fuzzy root this morning so it got planted. The breeder is Sweet Seeds. Looks like Oldsmokey was right about the seedlings. Just watch I will have two beautiful WW seedlings tomorrow as well. I’m not sure what’s up with Monster Zkittlez. It wants to grow, but no root.
I made up an approximately 40% citric acid solution to feed the root microbiome. I inject a couple of mL into the pump suction daily. I have been adding the hydrated spores every 4-5 days to kill off the fungus fly nymphs and degrade the dead rootlets.
I use REMO nutrients for a few reasons. They are Canadian. They don’t use ammonium salts except in the kelp suspension. I have found that ammonium salts cause the pH of my nutrients to drop, which is a real pain to correct. They also use a much lower P ratio than most other nutrient suppliers which I was looking for as well. I have switched to sulphuric acid instead of phosphoric to keep the P down. As previously mentioned I also boost the Mg content of my tap water from 15 to 50 mg/L. Ca should be OK at 160. I doubt I will need the nutrient chiller now that I have the LED but I will set it to 22 C and see what happens.
