Can I grow tomato plants and marijuana plants together?

Totally. Years ago, here in California a neighbor and I had a omato garden and some clever soul interspersed pot here and there. It grew like a...umm...weed, and then one morning it was gone. It was healthy and budded, so I'd say yup.

do you need the marijuana for medical purposes? if not why would y grow it

Any one alive right now probably knows someone who never grew out of using pot. If a person in Colorado uses it, why should they not be able to grow their own and know the quality and purity and not have to worry about chemicals and added expense to purchase it. Some people drink to relax, some smoke pot. I may not do either and don't allow drugs in my house, but I am not going to put down some who uses casually and safely.

Sure you can grow them side by side. A great way to enjoy a tomato sandwich and get yourself a Rocky Mountain high...

Yes you can. If you want to control aphids consider lady bugs. They will naturally eat the aphids,

Don't plant cannabis next to a tomato plant, as they will compete for sun and space at the peak of their growth. Also, overripe tomatoes falling into the soil could make it more acidic than cannabis. Squash and melons have wide leaves that attract powdery mildew, so keep them far away from your cannabis. If you need cannabis, better grow them apart from other plants or buy them from Best Oklahoma dispensaries. Cannabis plants are very pretentious, so it is not a good idea to try growing them together with other plants.

You can absolutely grow tomatoes with cannabis plants. No matter who says what. And fighting for a space? If they did that then no plans in the real world would be surviving except for one blade of grass probably LOL They will not fight I have done this they work fine but what also works better is if you plant more than one cannabis plant in the same pot prefer a fabric pot so they can air prune themselves without overcrowding the pot they will not fight and they do get along and plants do help each other out and communicate through their root system.

Your cannibus plants need a lot of room cause depending on the strain they could get huge. And besides that you need even more room to walk around to care for them.

We usually give each plant about 10 feet to expand but with some Sativa's you need to add at least another 5 feet.

Buy a bluelight gnats catcher from Amazon.

I see know reason why not!
