I asked the same question yesterday with no response. Luckily some maintanence guys came to my house and I borrowed their drill to make holes in a bucket. Now I can make an ONA bucket without dropping 70 bucks to buy a drill in a foriegn land!
you wouldnt want to spray it on the plants... that wouldnt be good. it shouldnt hurt the plants if you dont just mist the whole damn area haha.. you dont need to use much of that stuff either. its really powerfull. extreamly powerfull actualy. use it sparingly
