Good fit if you…
- want to start herbs, greens, or a few vegetable or flower seedlings
- have a windowsill, shelf, or table you can check every day
- are fine with a tray, a bag of mix, and some trial and error
Organic Living
Start seeds indoors with four basics, not a cart full of gadgets.
If you have a windowsill or shelf and want herbs, greens, or a few vegetable starts, you need trays that drain, a seed-starting mix, labels, and enough light. This guide helps you decide what to buy first and what can wait.
Is this the right guide?
This page covers a small tray-based setup you tend by hand. If that's not what you're after, another guide may fit better.
Look elsewhere if you…
- want an all-in-one unit with a built-in light: see countertop herb garden kits
- already have trays and only need light: see seed-starting grow lights
- plan to sow directly outdoors: follow the outdoor timing on the seed packet instead
Three decisions before you buy.
Settle these and the shopping list gets short. For planting depth, timing, and temperature, follow the seed packet; it's specific to the plant.
Is your light enough?
A bright, unobstructed window can work for some seeds, especially later in spring. If the spot is shaded or you're starting in late winter, plan for a small grow light. Seedlings that grow tall, pale, and lean hard toward the glass need more light.

Will the trays drain?
Cells or pots need drainage holes, with a solid tray underneath to catch water. A clear dome holds humidity while seeds germinate; vent or remove it once sprouts appear.

Will you know what's what?
Many seedlings look alike for the first couple of weeks. Label each cell or row with the plant and sowing date when you plant it, not later.

Also on the list, with no link here: a bag of seed-starting mix. It's finer and lighter than garden soil, which tends to pack down in small cells.
What to buy first.
Trays first, then a light only if your window isn't enough. Each button opens Amazon search results, not a specific product we picked, so compare dimensions and what's included on the listing.

Seed starter trays
The base of the setup: cells for each seed, a tray underneath, and usually a clear dome.
- Check for drainage holes and a solid bottom tray.
- Match the cell count to how many seedlings you can tend and transplant.
Small grow light
Useful when the window doesn't give enough consistent light.
- Measure the tray footprint and the clearance above it first.
- Check how the height adjusts and whether a timer is built in or sold separately.

A few herbs keep a first setup manageable.
- Read each packet's planting depth and days to germination.
- Choose herbs you'll cook with.
Plant labels
Seedlings look alike early on; labels save guesswork when it's time to transplant.
- Pick waterproof labels and a marker or pencil that won't wash off.
- Check that they fit your cells.
Before-you-buy questions.
Use the seed packet and product instructions for your exact setup; this guide is a starting framework, not a promise of a particular result.
What do I need to start seeds indoors?
Trays or pots with drainage holes and a tray underneath, a bag of seed-starting mix, seeds, labels, and a bright spot or a small grow light. Follow the seed packet for planting depth, timing, and temperature.
Do I need a grow light?
Not always. A bright, unobstructed window can be enough for some seeds, especially later in spring. If seedlings grow tall, thin, and pale, or lean hard toward the glass, they likely need more light, and that's when a small grow light is worth comparing. The seed-starting grow lights guide covers how to measure for one.
What should beginners avoid?
Starting more trays than you can check daily, leaving the dome on after seeds sprout, watering on a fixed schedule instead of checking the mix, using garden soil in small cells, and buying add-ons before the basics are working.
Keep building the setup.
