Not my expertise...25 fems outdoors???
Yup , thats what I used to do in my teens to camo my plants down the block from my house " Rail Road "Big towns use helicoptors, but they are up in the air most of time any way.
Hope you didnt plant em in rows.
Hope there not 14 foot sativas.
Hope you didnt put em in a state or natl. park they scour for weed every year.
Hope you blended em in with some local vegitation.
Hope you didnt leave trash, or make a huge path to em.
If you took the usual guerilla precautions they should be fine.
Tie some fake sunflowers to em to help camo em? I do
