Acclimating your plants before bringing them outside permanently is extremely important to having a successful outdoor grow… If you don’t acclimate properly from being a indoor plant / to a outdoor plant and rush the process to soon then you will get burned plants from to much sun, stressed from the hours they’ve lost to fast, and being cold shocked can all stress your cannabis plants and cause them to “preflower”. So By acclimating your plants and hardening them off to the outdoor environment you will have alot easier time transitioning them from indoor plants to outdoor plants.
