Good product to start seeds for a vegetable garden?

Good organic potting mix/potting soil, and/or a good seed starting mix.

Nutrient rich compost to mix an inch layer into the soil.

Consider also adding some beneficial bacteria, fungi, and more minerals/nutrients.

Containers with drainage help make sure you don't overwater, it's not necessary to have drainage holes in containers for indoor plants if your careful not to overwater.

The seeds could be started in any container, or you could start them in seed cells that each cell is about 1x1x1inch big. Then after it has sprouted you transplant each sprout to it's own container that is 3x3x3inches big.

A high quality water purifier that filters out all toxic chemicals the water, and use rain water if you can, you could also collect the top layer of snow and melt it.

Watering can/sprayer that allows you to have a rain like way to water the plants.

Warm temperature maybe about 70-80degrees.

Lots of sun. Led grow light.

Fan to provide a slight breeze to help strengthen them.

Some say nature sounds or music helps them.

Many plants usually do better if started outside from seed when environmental conditions are right, except some plants need to be started inside in some areas like colder climates because they take longer to be ready to harvest, such as tomatoes and peanuts. Soybeans should probably also be started inside.

There are bagged soil mixes that are specifically formulated to grow seeds. You can find it in your local hardware or home improvement store. When transplanting time comes around, amend the top soil with good potting soil. I use Miracle Grow with moisture retention abilities.

I plant a lot of seeds and I use Miracle Grow products always. They have a product that is specifically used with water for good transplanting success for seedlings to encourage root growth. Try that, too.

Other easy plants are Scarlet Bean Runners. These beans are delicious and the vines have beautiful bright red flowers all summer long. All you need is a trellis or wires criss crossed up a tree or on a fence and you will get plenty of beans without the plant becoming invasive.

I use regular commercial potting soil. Look for the word organic on the bag, otherwise it will have Osmocote pellets in it as modern manufacturers cannot concieve of a doo-da dumb-butt consumer being smart enough to know what they are buying. I run it through a sifter so there aren't big chunks in it . I am not a big fan of peat pots and pellets because I have had past experience where it was detrimental to my seedlings. If I was unable to tend my seedlings the peat can make them dry out faster, a peat pot rim above the soil line can wick moisture away from the seedlings roots(So always tear the top half inch or so of the pot off when you plant out). Peat repels water if it gets too dry.

I use plastic cell packs and yogurt cups,depending on the seed size and typical speed of growth the seedling is capable of.

If you need a soft germination mix for tiny or delicate seedlings try milled sphagnum moss. It also can get dry enough to repel water, but seedlings in this category will fail for a myriad of reasons if you are not attentive to their needs, and they are under the humidity dome longer, for the most part.

One of the easiest seed starting products to use is Jiffy 7 pellets. These compressed disks swell up when soaked in water. Any type of vegetable seed can be planted in the top of the pellet. No soil, no mess, just your pellets and seeds. If you are looking for a few other varieties to start from seed, I would recommend cucumbers, melons, and squash. Good luck with your garden.
