"All-Ball" Gorilla Zkittles Winter Grow

She's growing steady, had some nice white roots pop out the bottom. I think I read somewhere that once the roots reach the bottom and air prune they'll start more growth horizontally to fill the space. Watered twice or thrice this week with 1 liter each watering. The nodes are starting to grow their lil shoots, growing the third node spacing now. Still trying to decide how I want to train her. Originally wanted to try a manifold but thinking maybe a scrog would be better..? If anyone wants to put in their two cents let me know what you think I should do! I've never done either, only topping and low stress training.. I plan on having another plant in this space but it will be younger than this one by at least two weeks.. This week had been pretty easy though just checking the nutrient ph and getting it to where it needs to be and letting her do her plant thing!
