Tbh it’s only been in the last couple of years I’ve realised that big root balls are somewhat overrated in terms of yeilding.
I’ve had some solid 10/15ltr root balls that didn’t yeild great then other lesser root balls that can bend the branches.
I’ve made a few changes because of it which makes preparation more convenient for me, it helps not having to create a sizeable root ball during veg and i can use smaller pots.
