Seed starting doesn't need to be complicated. But most guides make it sound like you need a whole grow room setup. You don't.
I start everything under a $40 grow light from Amazon, in solo cups with drainage holes, on a wire rack over a heater vent. That's it. No fancy humidity domes, no heating mats except for peppers...
The biggest lesson: less is more. Don't overwater. Don't overfeed. Give them light and walk away.
