Add some greenhouse gasses

to promote growth. CO2 is a great one, if you flood your vegetables, fruits with co2 in the early to late morning they grow even better and faster.
Especially strawberries, they can get 50% larger.
I use the bottled co2 that is also used for welding, make sure it is pure co2 and not a mix.
Another source is dry ice, just make sure you not freeze your plants to death.
