Plants are extremely similar to Humans. The Vitamins we take are made from the same ingredients as plant nutrients. You try standing for days in heat with the lights on and see what happens to your body.

We always teach not to stress your plants. Not allowing plants to rest is stressing them. Period!

I said people that are experts. LOL If you are arguing for 24/0 photo period; You are no expert. Call your county agent and see what he thinks about you growing your tomatoes under 24 hours of light.
