Pumpkin in Same Pot- Plant Looks Really Healthy!

I have a young plant that in 12/12 (under a 600w in moss, perlite, vermiculite, and soil). I've raised it pretty much at 12/12 from about a week after germination.
There is a pumpkin plant growing along side it in the same pot. It seems to be incredibly healthy compared to all the others and has lovely dark leaves on it and much fuller (than the other plants) little baby buds as well. All round it appears to be thriving.
I wonder if anyone knows whether adding a companion plant such as a pumpkin plant could help marijuana to grow better?
Thanks.

LOL I guess it couldnt hurt it.
Happy Haloween

pumpkin grows HUGH roots and FAST.
how big is that pot?


there are companion plants that work with marijuana - marigolds are good for repelling pests and nettles said to help resin build up.
both are usually grown closeby and not in the same container.
