Ok so I guess I've been thinking about growing weed so much I had a dream about it and for some dam reason I had the seedlings growing in eggs like eggshells. I don't know if it's smart to do this but it seems like it would be pretty good you wouldn't have to worry about carrying around pots and if you just planted the eggshell with the seedling straight in the ground it would protect the seedling from weeds and I guess once the seedling got big enough the roots would break right through the eggshell and when the eggshell decomposed it would provide nutrients for the plant. I don't know just seemed fuckin weird to me that I would dream about that and that's the first time I've ever even thought of something like that I don't know if it's been done before or not but seems like a good idea.
Sounds like a good idea if there is a hole on the bottom of the shell. But you would want to roots to expand and grow out and now be contained in a tiny hole. But egg shells are good nitrogen sources for plants and always are beneficial in the soil.
You, sir, are going to create a holy plant. Jesus is your buddy. That egg thing will make Wonder-Weed of the New Age!
