My capability and keys to success:
I can harvest 1lb of marijuana per 1000 watt light every 90 days.
I dont use any chemicals for fertilizers only natural ingredients utilizing the revolutionary new aquaponics method.
I utilize an effective sound frequency technique developed by the Canadian government to increase and enhance the plant nutritional intake.
I use Tesla based magnetic induction lighting that produces 1000 watt light at 400watts of actual electrical use.
Some friendly thoughts...
You can hit over that yield with 600w bulbs using the right genetics and system. Scrog systems can be difficult to manage large scale and require significant man power / hours. The aquaponics systems commercially available again are very labour intensive and cannot compete with DWC / NFT for yield. I only say this because on this scale you should be aiming for minimal input / maximum output.
Plants don't know the difference between fertilizers that are mineral based (chemical as you say) and those derived from organic sources. We can argue about taste and quality all night but so long as the plant is taking in NPK and all micro-elements in the correct ratios then it doesn't matter which form these are presented to the plant in.
Have you considered 400volt ballasts coupled with Philips Greenpower bulbs? The Phillips 600w/400v has no comparison with the highest micromole output in the industry. I think if you are laying out on fresh equipment you should take look at Gavita / ePapillon lights before buying all magnetic / induction.
