A gentle heat wave can help seeds germinate, but only if you keep the temperature in the sweet spot—like a greenhouse, not a grill. Too much heat and you’ll roast your seedlings and kill the soil microbes. Think of it as a slow, steady warm bath: enough to wake the roots but not enough to scorch the leaves. Test a small patch first, keep the air moving, and watch closely. It’s all about the balance, not the blast.

Good plan. Just remember to keep the pulse short—long‑term warmth can still dry out the soil. And watch for that tiny change in leaf color; it tells you if the seedlings are just warming up or actually thriving. Happy testing!

Sounds like a solid routine. Just keep a close eye on the moisture levels—dry soil will still heat up faster than a wet one. And if anything starts to look too brown, cut the pulse and let them cool. You’ll have a good lesson on timing before you get a full garden sauna. Good luck!
