LESSON 1 when planting out best to let plants get to approx. 80cm in a 25-30cm pot and develop a good root system. The "PA" " Peruvian army" met this criteria and are booming in saying that most I planted that were 50cm ish with root systems are doing fine, but bigger root system the better. PS, ive had no losses, just slower development than I would like. EDIT - avoid planting cuttings with no roots, no matter the size, except sausage, that thing powered from word go with no roots.
