Well I had a freebie pack of Brown Sugar X Long Bottom Leaf from Bad Dawg, and I germinated as per normal, paper towel method, until they cracked open a bit, and then I put them into jiffy pellets as was becoming my favorite most reliable method. I have done a few pops like this recently but thought I would improve this run and put the dish of peat pellets into my humidity dome where the humidity was 95% and temps 70-80F. 1/9 came up 3 days later, and day 5 none of the rest had yet come up. I finally dug into them and saw that none had done anything, when squeezed they had the creamy puss inside explode. Some taproots just seemed to rot at the tip. Something happened to them in there, and based on sprouting development it happened day 1 or 2 of being inside the dome.
All these germination trays etc. come with humidity domes. I thought 99% RH was what you wanted until they sprout out of the ground.
I have no idea what happened here. I know you don't need to PH soak the jiffy. I know that regular tap water is fine. It has worked fine on the last 3 batches. So what the hell happened ? Should they be exposed to moving fresh air even when undergound still?
My understanding is that "new seedlings" require high humidity because until their roots get established, their uptake is through the leaves. So I use the dome and never had any issues with seeds dying off (knock on wood)
IMHO one should sit down (unmedicated) LOL and figure out the common denominator when troubleshooting. So you have had success in the past then, all of a sudden... How deep are you burying them? Could it be associated with sub par seeds for whatever reason, etc? If you have any seeds (from successful runs) left, try striking those as a benchmark so to speak, and see what happens.
Forums are great but they can be a pain, regardless of topic. Opinions are like belly buttons! When faced with a dilemma, I ask myself if the entire commercial industry uses humidity domes and, as is well... Where did I screw up?
May the fleas of a thousand camels infest
the crotch of the person who screws up your day and,
may their arms be too short to scratch...
