Here is what I did:
I got one of those Jiffy little “greenhouse” trays. They have 72 little things of soil. I filled it full of water and let the soil expand. Then I put in my seeds and marked each row what they were (very important step to NOT forget!). After a couple days and after all of the seeds sprouted I took the lid off. I water every couple of days and they are growing like crazy!!! Once they got pretty big, I transferred them into these bigger containers so they could have room to expand.
Now I am at the step of hardening the plants. I am going to take them outside in the shade for a couple days. Then I will gradually expose them to direct sunlight. Then I will put them in my garden!
