I would say its totally worth it. You have a good 2 months of solid veg time. They will be about 15-20 foot tall just so you know. Just make sure you are only watering the root zone and only every 3-4 days. It will take a month for the roots to fill the pot.
Im currently growing in some 65 gallons and have trouble with watering finding a suitable amount started with 5 gallons but feels like im watering every other day
