Know When to Start Your Seeds
It’s important to know your climate and last frost date. You can find yours here. Try not to only pay attention to what others are doing all over social media. We all have different climates and growing zones.
Some indoor seeds need started as early as 12 weeks before like onions and celery, and several herbs like rosemary and lavender while others only need 6-8 weeks indoors like tomatoes before planting out in the garden.
Know What Supplies are Most Essential
Here’s a list of the main things you need to get started.
- A grow light (very few can make it work on a sunny south facing window).
- A Heat Mat
- Seed Starding Mix
- Seed Starting trays with a humidity dome or a plastic wrap.
I stared with store bought seed trays and potted up into plastic solo cups and nursery seedling containers.
If you don’t want to invest in seedling trays at first you can try using stuff you have around the house like plastic yogurt containers, solo plastic cups, plastic produce containers or egg cartons (all doable, but have their challenges).
Just make sure you drill or poke drainage holes in the bottom!
Here’s a list of the supplies I use:
The Seed Trays I use:
4-Cell and 6 cell Trays with air pruning side slits
Epic 1020 Universal Bottom Tray (for bottom watering)

Ensuring Your Indoor Seed Starting Success
Successful indoor seed starting goes beyond buying a few packs of seeds; it’s about being prepared by having the right supplies, knowing which seeds to plant, when to plant and having an introductory understanding of each stage of the process.
