Seed was submerged into 15ml of 0.5% H2O2 solution in a corresponding glass jar for 12 hours to soften its shell and prevent it from bacterial attack. 5. A Root Riot cube was also submerged into 0.5% H2O2, but in separate container. It was submerged for 12 hours to sterile. ===== 12 HOURS LATER (12/13/23 11:16 PM) ===== 6. Germinating temperature is recorded at 21.7c. RH is irrelevant since a humidity dome will be used. 7. Root Riot cube is picked out off the H2O2 bath and drained off excess liquid by shaking (!!!NEVER SQUEEZE THE CUBE!!!). 8. Seed is sowed ~0.5cm into the opening hole of Root Riot cube. 9.
