However – if you’ve done several successful crop-outs, and want to perfect your growing game – these changes become a necessity. You need a journal to jot down dates, measurements of weight and height, lighting schedules, etc. This helps you become a better grower by creating data sets that can be improved upon. You simply need to embrace the discipline of a master grower. It’s not always easy – but it’s the only way to “up your game” if you feel like you’ve hit a wall.
