Here are the pictures of damping off. Also I sprinkled cinnamon on top the tray cells to try and stop it.

oh and to add,heatmats are usually used when people seed start just before spring and its still cold,so if your temps are already up and the nights are warmer i wouldnt use it. Unless you grow in a cold area like a garage or shed,you get the idea.

The problem is that heavy mix.  That's not a seed starter.  It holds too much water, and not enough oxygen!


EDIT: I didn't notice previously that you are in South Florida.  You need to lighten it up, bro.  This is the beginning of our wet season, and humidity abounds.  If this were me - and believe me, it is - I'd be starting the next round of seeds in something more like a 70/30 peat/perlite mix, or 75/25 coco/perlite.  Easy on the waterings.


I definitely agree with you 100%
My new seed tray is a lite mix about 70/30 peat/perlite.
Im going to hold back on watering my third tray this time too.
Do you think it's a good idea to leave the dome and heat mat on until i see any sprouts?

My other two trays have the domes off with cinnamon sprinkled over the tops of the cells and lights over them but i think they a looking a bit dry on top, i'm even worried about bottom watering them

If damping off is already present in your trays, and you'd prefer to save whats left rather than start over, I'd personally go straight to captan fungicide ASAP.  The disease can come from any number of strains so there is no guarantee captan will kill it.  It wont save the plants which are already infected but will prevent damping off from spreading to surrounding seed cells.


As for future prevention, I find the advice here to be helpful.


For a fungus to spread you need three things.  The pathogen needs to be present, you need a host, and you need favorable conditions.  Eliminate one and your problem never materializes.  Obviously you cannot remove the host.  You can mitigate the danger of favorable conditions to some degree, but you can never completely get rid of them.  The only surefire way is to make sure the pathogen isn't present at sowing time and doesn't enter the system at a later point.  Start with a sterile mix and keep everything clean.


Thank you I appreciate the helpful info, also the damping off link too
