Stem Support Question

Hey I have wanted to know. 1)When the plant is growing from a seedling and the stem gets longer and start leaning how do you keep it from falling over?
2)If I have my plants in stater cups, would you reccommend or think it'll be safe to take them out and put them in a 5 gallon bucket to support the stem without the roots being completely compacted?


Thanks!

Your plants might be stretching support them with something and you should have a fan on them to blow them to stiffen the stem

And it should be ok to transplant just dont compact the soil around it

Thanks alot!
