  1. The one where thay said its abit hard to grow tomatos under the LED. Thats bullshit,, i have tomatoplants under growlights, I get fresh tomatos every week, I i pick the whole plant today, next weeek it will be full of tomatos again.. but agian, i grow in rich nutrient soil with weekly fertilizing.

  2. Can anyone tell me the complete cost of this vertical farming ?
    And can we grow fruits like guava , pineapple , mango , strawberry and vegetables like cucumber , potato , lady finger.
    And what is the cost of LED lights setup ?

  3. Even with recent improvements in PV and LED tech, you're still looking at what, maybe 10% efficiency in delivering light? Might there be some way to collect light with mirrors, route it through pipes (maybe fiber topic cables), convert the green to red, and distribute it to individual plants? You could still use PV+LED to distribute artificial light for fine balancing, and for cloudy days and some of the night-time.

  4. Food off the ground good. I like that part. After the where house falling down during that storm recently I wonder if the warehouse shape should be a pyramid. I was taught that is one of the strongest shape structures. Does anyone 2nd this notion.
