Honestly, I'd run LEDs. Dropping your electricity costs for lighting by 20-30% is huge. With a setup like this, I would expect about $30,000 per month in electricity just to run the lights. $6000-9000 less pays for your grower, and a trimmer or three. Are they expensive? Well, sure. Are they worth it? Uh, yeah. 12 year lifespans instead of 6-12month lifespans for bulbs and 5 year for ballasts. And considering this is Canada where it is federally legal and, lets be honest, that isn't going to change, paying attention to long term pay offs in terms of electricity savings is an important thing to do.
