👉The flowers are starting to build, this is an F1 auto and is supposed to have a fast flowering period. I've been changing the nutrient mix to try and keep up.
I use those same racks. I drop ropes over the rack into a 1 gallon ice-cream tub, then set the plants on the ropes for wicking (rather than as a catchment for runoff). Hadn't considered the tennis balls on the feet, that's a good idea. 👍
