Yes, space them out. Just from a financial standpoint it isn't worth the fuel to locate a small grow. They are after the big boys, who don't space the crops out. FLIR has a difficult time pinning weed down if it is mixed with other soft herbaceous plant material. So growing amongst a lot of trees without a lot of underbrush will expose you more to them.
