ZooL Posted December 14, 2020 Share Posted December 14, 2020 Recently i ran out of rain water and have had to fill up my water tanks with bore water, i am now getting some serious issues of damping off on seedling when i transfer them from germination domes to filtered light areas, i have noticed that it is more of a problem when i water them after the top soil in the pots has dried out a bit. does anyone know of some good resources focusing on damping off or suggestions to prevent it?

saguaro Posted December 15, 2020 Share Posted December 15, 2020 Hey mate, damping is caused by fungus so reducing moisture and increasing air exchange will help. You could try using a soilless or sterilised media to germinate in. Cleaning organic matter and spores from your propagating gear will help, as will lowering sowing rates. I'm curious if you know the pH of your bore water, rainwater is usually around 5.5 which is optimum for seedling growth but your bore water could be higher, which would favour fungal growth. 1 Quote Link to comment Share on other sites More sharing options...
ZooL Posted December 16, 2020 Author Share Posted December 16, 2020 Nah , not checked ph of bore water. I had assumed because i was sterilizing soil and the change was so dramatic after only the water change being different then it must be something in the water , but yea could just be some of the gear im using that is contaminated and the bore water may be making a too favorable environment for it. Thanks, will check ph of water and give all the gear and tools a good clean. Quote Link to comment Share on other sites More sharing options...

migraineur Posted February 17, 2021 Share Posted February 17, 2021 A heated propagation chamber or heat mat can help dry the soil out quicker as will giving the medium more access to light and fresh air. Furthermore, if you use perlite then the soil will be less soggy. Coir won't become mouldy as quickly as soil so you could use that depending on what you're growing, otherwise a soil that has more sand and some perlite added will help with drainage and aeration. What are you growing that's having the fungus issue? Quote Link to comment Share on other sites More sharing options...
