Newbie question about mites/bugs/mold.

[Loc Dog]

I am a newbie to this section. I put some plants out once, in empty above ground pool, brought them back in, and spread russett mites and thrips.

I plan to finish up an indoor grow in July, and wanted to try re-vegging. Should they be sprayed, or have companion plants that they would prefer?

I have just about everything for bugs, diseases, and mold, after losing a couple of grows.

Thanks!!
