Wann soll meine Wachstum Glühbirnen geändert werden?

No matter what time I start them—early or late—my seeds invariably perish or mold. I have no idea if I water them excessively or insufficiently, if they are too hot or cold, whether I should keep the cover on the tiny glasshouse plants or not, or what else. I have no trouble growing anything outside, but evidently not inside. Any tips for seeds starting?

I got some seeds from the local grocery store. How to grow them indoors?

Kürzlich, Ich habe eine LED-Wachstumslampe für den Innenanbau gekauft, but I’m new to gardening and I’m not sure how far away from the plants the grow light needs to be.
