i grow in pine trees, and i've been doing it for six years. there are 2 gallon hanging bags you can buy that have five holes for plants to grow out of, i tape em all closed but the top one. fill it with fox farm ocean and take em to the top. i put two plants in each tree and i mostly use feminzed seeds for this. put a bucket at the top with two hoses runnin down to your plant bags, if it dosen't rain for a week or so just go water em, other than that the bucket will catch rain water.

you may think this is alot of work, but it's not, i check my plants prolly four times a summer on average, and i've never seen a deer climbing a tree.

i've lost more pot to deer than i have to assholes
