These are already somewhat large to begin with but not that dense and tall. You just need medium to high light, high fert, and high CO2. After 2 months or so, it would take off. Add plenty of water current too. At first, you may get some leaves turning black due to the amount of light. Just trim those and the newer leaves would adapt the condition.
