I'm just a fan, it's super easy to grow, just water and you're good to go. I water from the top and from the bottom since top watering can get time-intensive. I would recommend starting to fertilize organically from day 20 to avoid any deficiencies during the bulk phase. However, I have to say that even if deficiencies start early, I've always had top results with this soil! So you can definitely do well without fertilizer :)
