FAQ

Do I need all three?

No — start with the #1 Burpee kit on a sunny windowsill. Add the grow lights when seedlings get leggy, and the heat mat to germinate peppers and tomatoes weeks earlier.

When should I start seeds indoors?

Most vegetables go indoors 6–8 weeks before your last frost date — the heat mat and lights let you start on schedule even in a cold house.

Where can I buy them?

All three are available on Amazon — tap any "Check Price" button to see the current price and reviews.

Our Final Verdict

If you buy just one thing, make it the Burpee 72-cell kit — it's the complete starting system. Then add the Barrina lights, because light is what separates stocky seedlings from spindly ones.
