fast buds tent

most grows in these 5 gallon pots, i generally water them twice a week, the first watering with main nutrients and about 3-4 days later when the pots are much lighter, i water again with cal-mag approx. 2-3 ml per liter and occasionally add great white mycorrhizae. i dont always add it if the plants look healthy, but generally want to make sure it has enough because ive made mistakes in the past.
