Help Fast Please!!!!!

Hi
After reading all of the great results with rockwool, I ordered some, but had also seen some info on using sponges as a method for starting seeds and decided I could try that while I was waiting for the rockwool to arrive.

In one of my genius moves I started 4 ice cube trays of various seeds in foam type sponges cut into 1 inch cubes. Much to my amazement after only 24 hours some of these have all ready started to form roots!!!
I am so excited but the problem is that I have no idea what to do now?????
Do I wait for them to develop leaves? Do I pot them up the minute I see the root? I am planning to just trim around the sponge slightly and plant the whole thing in pots of either seed started or potting soil. (or maybe try both to see what works best.
I can't believe all of the wonderful information that is available on this site, now maybe I need to start reading more before I jump in and try things!!!!!
I need to move them out of the bags that I have them in at the moment into things that I can keep from touching the tops of the trays. I have them all together in a zippered sweater bag, will switch them into individual bags that I can blow some air in and keep off the tops of the sponges. I am hoping that is the right thing to do. I am also wondering if I should have these under lights? At the moment I just have them on some heating pads at 70 degrees. Any advice will be greatly appreciated.
The sponges were really easy to work with and my granddaughter and I had great fun doing this, it was neat, easy, and clean and allowed her to do a lot of it by herself, which was great.
I bought these sponges at a cost of 10 for a 1.00 and made 10 cubes out of each one. In planting large seeds I put in one seed each, but the smaller seeds we did, I put 2 or 3 in each cube. I am not sure how this measures up in expense compared to the rockwool cubes, but it obviously is just as easy and no waiting for my order to come.
I so far have moonflowers, and love in the puff seeds that have both sprouted roots. The nasturium (not on heat mats) and scarlett runner beans have both started to develop openings in the shells where roots will form I assume.
Anyway, now that I accomplished this much, I am really unsure what to do now?????
Any and all suggestions would be appreciated. I have enough started to try one or more different methods to see which will give the best results.
Thanks all for taking to the time to read and respond!!!!

Alice, there has been some previous discussion on starting seeds in sponges. Here's one link:

Thanks Darius
That is the thread I had seen and gotten the idea from. I re-read and it looks like I should wait for leaves. Put the trays down into aluminum foil pans to keep the plastic off the tops of the sponges and let them do there thing.
I am so excited at my results that I am sure I am getting over-eager!!!
I shall try to patiently await some leaves.
I have some acer palmatum seeds started and those are the ones that I am really hoping to have success with.
I also just read notmartha's post about the way she starts daylily seeds and now I am really sorry that I wintersowed all of mine!!!
I have some asiatics left, but doubt that they would work the same with that method.
Thanks so much for your help Darius.

Alice, I'm probably going to try this method in March. I'll be late getting seeds started but cannot help that as I'm moving at the end of February.

It's enough to move all my house plants In February without trays of seedlings, too.

I remember reading that you were getting ready to move!!!
How exciting!
We have only been in this house for slightly over a year and when we moved I brought about 150 plants with me. I potted everything that I could from the other house (we moved in October) and them put them all in an alcove here in the back yard. My son in law got bales of straw for me and we buried everything under about 2 feet of straw. I lost a few things but much to my amazement most everything survived. It was a huge challenge last spring to dig and get places ready to put everything, and one I am glad that I don't have to do again. I didn't have many houseplants, and I am sure you will have a huge challenge with those.
When you need plants for all of those wonderful new garden spots let me know, I should have plenty to share!!!!

Thanks for the offer of sharing plants, Alice. I have about 50-75 pots of perennials potted last Fall, and buried in leaves. Some are quite large and I hope most survive. Plus, I can come back and divide perennials in early spring.

It will be an interesting journey, LOL.

How wonderful that you will be able to go back in the spring, I knew that I would not be able to do that. Actually the people that bought my house pretty much destroyed everything I had done (I guess they were not flower people)
I took everything that I wanted and then invited several friends to go get what they wanted (I am glad now that I did) There are starts of my plants in several places now, which is such a nice thought.
Moving is definitely a huge adventure, and I know you will be glad when its over!!!!
