Constant light during veg is a habit some growers swear by for photoperiod feminized plants, on the theory that more hours mean more growth. The gain over eighteen hours is small, the power bill is a third higher, and a plant with no night at all has less margin when something else goes wrong. The schedule recommended at https://queenfeminizedseeds.com is 18/6 through veg, with 20/4 mentioned only as something seedlings tolerate. I have never seen a side by side grow where twenty four hours justified the extra cost.
