OK! So In the above picture we have pepper seed a towel and a pen. Make sure your ink does not dissolve in water! Just write on a towel and test, it will be obvious. Make sure to label if you got lots of varieties. What I show here with peppers can be done with all the vegetables.
Here's the towel method.
Get the towel wet, then add the dry seed. Give them some space so they don't get roots all tangled up for transplant.
Roll it up like this
In a container, put about this much water
You can Add 1 drop of bleach to prevent your seed from being all moldy, but not usually necessary.
Put your towels in with one or both ends touching the water to keep the seed moist. I rubber banded the packet's on these beakers.
Cover with plastic to retain moisture and put in a warm place. These are on my heating vent.
So that's it. Ideally you want 80 F temps and all this stuff will sprout in a week. At the store you can get those covered seed trays with the peat pot's, but plastic bags work just great.
**** A heat mat for veggies is also very nice and can speed up growth
The rusted veggie guy's blog did some nice youtubes on all this stuff. http://therustedgarden.blogspot.com/p/how-to-start-seeds.html He does a great job and I like his setup. So check it out.
