If you are transplanting out that early, expect MONSTERS. Any plants you saw closer together were either from clone and set out in July, or from seed and STARTED in May at the earliest.
I'd say wait until June or July to set out your plants if you don't want them to finish over 4 feet, LST them, and pick short strains.
