Catnip, Basil And Lavender Same Grow Room?

Can I put catnip, basil and lavender same grow room with Marijuana?

Or do I have to worry about cross pollination?

I grow everything outdoors together so I know I dont have to worry about catnip, basil or lavender.

Also, you think all the above will do well under 20/4 of light?

correct, herbs will be fine, just dont put chilli plants in, greenfly will enter your room

Thanks for the responses guys.

No, cross pollination would never occur between two different species of plants. It's like asking if there would be cross breeding if you placed a dog and a fish together in the same room.

tell that to the foxface rabbit fish, jk

Catnip is part of the mint family. There are a few different strains of catnip out there. I've seen a cross between a ground covering plant and catnip that sorta would be the Lowryder of the catnip family. I also have a japanese catnip strain that came all the way from china(name misleads origin). What I do know about my regular-catnip is that it flowers during the summer months when there is a longer photoperiod. It vegetates during the spring months where the photoperiod is more like the marijuana's bloom period.

So to bloom catnip, put it in your marijuana "veg room"
To veg catnip, put it in your marijuana "bloom room"
Harvest, dry and cure the catnip buds just like you would your marijuana buds.

Edit: under 20/4 light, catnip will bud.
