I am constantly trying new ways to start seeds or get bigger plants for a season. Below is my basic seed starting setup. I use LED lights and flats of various cell (pot) size. I find that setting newly planted flats on the top provides a little bit of heat for the flats and helps increase germination. I do cover those flats with a clear cover to reduce drying out. I'll use overturned flats and/or milk crates to raise the flats up closer to the lights.

Larger Basil and Pepper plants are at the bottom

Certain large seeded plants I start right in larger pots as that gives them plenty of room to grow on without transplanting.

In the smaller 98 count flats, I do rows of seeds and use the labels to demarcate how much for each row.

I have been starting lettuce in the 98 flats and then once they fill out I transplant them to window boxes to grow on.

I've discovered that though the lettuce seedlings start out leggy and spindly, as they grow they fill in nicely.

It's hard to get  large vigorous pepper plants unless they are started very early. I'm trying this technique.

I expect that I'll be able to grow these plants in these small "cells" for a few more weeks. You can

see that one of the smaller peppers are the Habanero peppers, they are notoriously slow to grow.

Spilanthes is also called "Toothache plant", as it has a slight numbing property.

It is also interesting to note that Basil's first leaves have a distinct "D" shape to them.

These tomato plants were started February 20, 2020. Hopefully I'll be able to keep sizing them up.

If they get too root bound they won't grow as well when planted out.

Half the fun of growing things from seed is to try new things.

I've started some watermelons extra early to see how big I can get the vines before planting them out.

I'm also going to see how these Nasturtiums do in containers. These are some unusual colors that will be fun to try.
