Laying some pipe I will have ~5ft. of flexi tubing coming off each of those upright pipes. From the flexi tubing, I will have 20 spaghetti lines coming off the flexi tubing with dripper stakes at the end, going into 20, 3 gallon grow bags, where my plants will be loving life. I have a ball valve at the base of each upright. My rez will be outside the room. I fill up the rez with whatever the 20 plant section needs and turn it on until it drains all out. They're good for 2-3 days. 120 plants will be taken care of in about 10 minutes. I'm using the PBP line with Liquid Karma and Sweet and I love it.
