Q.Indoors Seed Growing

Zone 93555 | Anonymous added on February 15, 2026 | Answered

When I try to start seeds indoors, the seedlings always get very tall and leggy. So much so that they can’t hold themselves upright. I’ve tried just about every combination of soil, peat and coir pellets. In a terrarium, not in a terrarium, etc…. Any advice you can send this way would be greatly appreciated. I’d love to get an early start on my plants and save some money. Thank you

It sounds like lack of light. Seedlings grow best under a grow light that is just a few inches above the seeds and moved upwards as the plants grow. If you have a south facing window you can try that and turn the tray every day or two to keep the plants from reaching for the light. Here is more:
