Rumpleforeskin is currently doing a fully controlled LED test. 2x 180W LED lights, 1900ppm CO2, 82 degrees. The LED lights were supplied to him by a vendor and they set all the growing conditions. He normally grows with a 400w HPS in his setup and pulls 10-16oz per harvest from 1 plant. Should be interesting.
unless were talking about auto flowerers or something in a small box, you cant really measure productivity in grams per watt, people want what their used to or better.
many will need to see their normal large central colas, on happy spaced out plants, before they swap over to your led units.
