Self-Watering Seed Starting Trays

Hello. I recently purchased a Jiffy Self-Watering Greenhouse to start seeds in. I planted a bunch of stuff about 2 weeks ago but so far absolutely nothing has sprouted. I have a heating pad underneath and have never had problems getting seeds to start in a non-self-watering tray before. Most of these seeds are things like melons and squash so it seems like they should have sprouted a long time ago.

Is it possible that the soil is too moist as a result of the self-watering system? I picked this up because it seemed convenient since I wouldn't have to water all the time but if none of my seeds come up it seems rather useless.

How do they look, are they sitting in water?

Do they look really moist?

What medium are the planted in....peat moss, soil?

They seem very moist but not soaked. They're in those starter pellets that came with the setup.

Do you actually keep the resevoir underneath full of water all the time? Or did you just wet the pellets to get them to 'grow', and haven't added any water since?

I keep the reservoir full of water and add water fairly often (the instructions say to).

Well, the instructions stink. :) To put it politely. Those self-watering thingies are ok if you use them like you would normally bottom-water with any other container; that is to say, pour water in the resevoir when the cells are dry, allow them to soak up what they need, and dump the rest. Seeds won't germinate, and seedlings won't grow, in a constantly wet, soupy bog. Which is what peat/soil will be if you allow it to sit and soak up water all day long. Sorry for your struggles, hopefully you still have enough time to get some new starting mix and seeds and try again; this time, wet the medium, squeeze out extra water, fill the cells, add seeds and cover. Don't water again until the seeds sprout and the soil is dry. Hope that helps!

Thanks for those tips. I'll try that. I just planted some passionfruit seeds about 2 days ago so hopefully I didn't ruin those. I don't really care about the other stuff I was growing as I have my vegetable garden mostly planted. I was just experimenting with seed sprouting since I'll be growing a lot of stuff this year with my new greenhouse.
