Trying a new medium mix

Bushland, TX(Zone 6a)

Mixing equal parts peat moss,sand and used coffee grounds,hoping that it might keep more moist,having to water less.Some clematis seeds Tanguita Aztek says need sun to germinate,so I'm not even covering with plastic,this is in the greenhouse and not outside,anyone have a good medium they use with less watering?

I don't think there are many mixes that stay wet more than 2 or 3 days besides saturated clay , and most know the problems with that ,
Sometimes humus will hold water longer , only it is difficult to saturate if it ever gets to dry ,

I never found one that really works, but I did find an alternative that helps a lot at keeping a seed flat moist-Years ago I got a seed starting kit from Gardener's Supply, they still sell something like it called the GrowEase System. The planting cell tray sits on a capillary matting that goes down into a water reservoir, it sucks up water and it goes up into the potting soil without staying too soggy. I think some people make their own with flannel or felt or something, but the kit worked fine and I still use it sometimes twenty years later.

An old towel works too.

Tropicman, interested in how peat moss and coffee grounds work being they are both so acid.

Well here's what I've learned so far,the mix is hard to re wet after going dry,if kept moist seems to work well,but that means watering everyday,I was using a potting soil mix too,and it seems to stay more moist than my mix,and it seems the lemon grass seeds germinate better as well,will update again when I have more to tell.

Spraying a dry soil surface with a spray bottle first usually makes hard to wet mixes easier to water.

I use to always water from the bottom,but was having to much problems with rot,so I went back to watering from the top again,I have a small watering wand,used from insect sprayers,on a old shampooer hose,works great,can even mist plants as well.I have a 55 gallon drum filled with well water,inside the greenhouse,so the water is room temperature,the hose is hooked up to water utility pump,works great,and when its time to fertilize,I mix water soluble fertilizer to the water and feed my plants.

some of these commercial soil mixes have to have the whole pot dunked to moisten if allowed to dry out.

I use Top Notch Premium Potting Mix when I can get it. I don't have to add anything to it. It moistens well, holds moisture well, and is easy for delicate seedlings to push through
