I would probably just buy rockwool myself. But I believe the stuff you're talking about is found in the area where silk flowers are located. It's generally used as something to stick the metal end into to act as a base and hold things up.
You'll find it at wal mart too.

Now that I have pulled OUT my herb seed plugs,...I finally got my tomato kit, along with all the others I bought. I didnt want to wait 6 months to plant my tomatos. So I see these are planted in a sponge that is like the throw away sponge brushes for painting with varnishs or shelacks. Very light and porous. I looked into the rockwool situation, and the company that sells it said it would work great in my AeroGarden, just soak it for 1-2 days and rinse out before planting into it. To get the PH right? So I might just buy a small package of them off of EBay,they are round and have a slit cut in them already! Already to go!

I planted the tomatos,turns out you only get 2 red and 1 yellow tomato plug planted and ready to go. Then 4 empty plug spaces,it makes room for when the plants are big, down the road.

I saved the sponges and baskets and domes from the herb kit and when/if I get tired of tomatos, and I want to try it. I can plant my dwarf marigolds, use the 'petunia setting' for lights and food, and see what happens. I put in 1 plug with new dwarf marigold seeds in it to see if they sprout and if there will be room for them, once the tomatos grow. Its day 3 and so far no sprouts. Boy I'm impatient!

IF I actually get another unit for Christmas,I'll plant up lettuce or salad greens in that one. OR maybe do the petunia kit! Everything that I cant grow out side for more than 2 months, without bugs or something else killing them. The heat alone usually gets to them. So I still dont know where to get this sponge, this light and airy sponge,but this Rockwool seems to be the next best choice?

Welcome, Johnny! Here's what I'm thinkin' 'bout the dealio. What kind of tomato is that 'un? If it is a hybrid tomato, you might be disappointed at the results. If is an heirloom (aka open-pollinated) type. This website is a rich source of knowledgable people, so take advantage of it. And for Pete's sake, if you fail, try again, and again... Nobody ever learned all this stuff overnight. And most of all, remember.. "Nature, to be commanded, must be obeyed." Best!

where do I get rare coleus seeds?
Q
Comments (6)
I have been growing coleus from seed I have collected in the previous years garden. All of my seeds have done really well. Every time I buy a new different coleus from the ones I already own, I let the plant mature and then collect the seeds from the flowers. My coleus are beautiful. I have a lot of different seed and never bothered to get their proper names. I have seed for exchange if you should want any.

Yeah, I would have waited until they were very orange and falling from the tree. Still, they may germinate. They're about the easiest things to start. Peel off the outside, wash the seeds. Throw them in a pot, water and watch them grow! I wouldn't think you'd need to soak them.

Help, how do I get 'Great Stuff' foam off my hands?
Q
Comments (195)
Getting Great Stuff foam off your hands can be challenging, but here are a few methods you can try: Use soap and water: Try washing your hands with soap and water, as this may be enough to remove the foam. Use warm water and lather your hands with soap, then scrub the foam off your skin. Use acetone or nail polish remover: Acetone can dissolve Great Stuff foam. Apply some acetone or nail polish remover to a cloth or cotton ball and rub it onto the foam residue on your hands. Be sure to wash your hands thoroughly with soap and water after using acetone. Use a pumice stone: A pumice stone can help scrub the foam off your hands. Wet the stone and rub it over the foam residue in a circular motion. This may take some time, but it can be effective.

I'm not sure your sponges are going to work too well. they're porous, but I'm not sure the roots will be able to grow through them.
Rockwool is a time tested favorite of hydroponics. you soak them overnight to correct for pH. I don't really understand it and that's why I don't use it. Also, i believe its not entirely environmentally friendly. Just fill your net pots with lava rock or pea gravel. If you're worried about the seeds getting moisture, just run some cotton string down through the bottom and set the seed against it. wicking will keep it wet and the roots will grow down the string toward the water source.
also, coir is a very good medium to hold your plants in. its made from shredded coconut hulls. looking at the AG, you could probably use jiffy pots to start your plants in.
