As soon as my seeds sprout, I take them out of the oven and put them under the grow light. I do not rely on window light to produce healthy seedlings, I've had much more success putting them under grow lights. they are not as leggy and have a greater chance of making it to a full plant size.
How do you start your seedling?
I also used some tires I collected last year as planters for some squash and beans. I only have a limited amount of space in the back yard, so I need to maximize my planting. The is the first time I've used tires so this will be a fun experiment to see how well the plants grow.
