I am a high school student developing an experiment on the topic of Electro Culture, the study of electricity on plant growth. I'm thinking that i will use 4 flatbeds with 36 kidney bean plants in each, while varying the amount of electric current on each flatbed to form my IVs. However, i'm not sure how to channel the electricity to the plant while still controlling the voltage. Also, it needs to be a safe setup. I can rent a generator if needed, but I've got no clue how to do this. I'm doing my own research now, but help would be very much appreciated.
