zone 5b/6a! apparently my city is split in half LOL - well, according to fda. the labels on all the seeds say 7, though.

they are planted already, sorry - but not outside! everyone's in a temporary pot until the end of april to help get them started! i wheeled them out today on the wheelie shelf they're on since it's been ~70 all week but i plan on putting them in front of my window when (if?) it drops again.

My plant the stem broke down from the bulb will it grow back this. Season

Depends on what the bulb was. But in true bulbs, no, if the main stem is broken off it won't regrow. What bulb do you have?

That really isn’t true. Again as you said it depends on what it is. But lots of “true bulbs” whatever you mean by this, like daffodils, Lycoris, Lillies, and all kinds of perennial bulbs — they lose their stems every year dying back after blooming. Same with herbaceous peonies — they come up in the spring and die back in the fall. So it really depends on what the plant is. I would check with your local botanical garden or the society of whatever plant you have if this happens to you. Obviously this post was back in 2020 but for those that find their self in the same situation — do some checking with reliable sources in your area. Even your county extension service ie the gardening dept ask for a Master Gardner. There are many universities with gardening depts.

I will caution one thing — many plants aren’t meant to be house plants and you can end up weakening the plant instead of helping. Only plant when the seed package says so not any earlier. If you bought from a reputable seed company, you can go to their website or call their customer service and ask questions. Most houses don’t have proper light for those plants that need really bright light. If you are starting plants for the upcoming summer in 2-3 months for example, you need a grow light that is full spectrum and it set height wise at the right level. Too far away and might not as soon have it, too close and will burn it up. You need to figure out how much light you have coming in and from what direction and for how long. For example geraniums, tomatoes, peppers need quite a bit of light min 6 hours a day and preferable 8 bright full sun outside. But anything less than 6-8 hours ends with weak not productive plants. Think about it the sun is up early in the morning and down at almost 8-9 in full summer. 14+ hours a day.

"That really isn’t true."

I beg to differ. I was answering Preety, not the OP. Preety asked if the stem of a bulb would grow back. So the 'it' I was referring to is the stem, not the bulb itself. So what I said is true. In a true bulb, the annual flowering stem will not grow back if broken off. Next year a new stem will grow. Perhaps I should have been clearer.

"“true bulbs” whatever you mean by this"

In botany the word 'bulb' has an accepted definition and that is what I meant by 'true bulb', not to be confused with a corm, tuber or rhizome and definitely nothing to do with the roots of things like peonies or other herbaceous perennials.
