Which hydroponic system is The best,this my first time doing growing,I going to grow 4 plants but i dont know which system would be better for me,Thanks
Look at using bubble buckets. If you have any building skills you can easily make one yourself. Plus all the parts can be obtained at any good hardware store. There is a pic of the ones i built on my grow journal. The widow grow link below, if you want to check it out. Mine are all connected with half inch pvc, makes it easier to change nutes, but not necessary.
