Saguaros are extremely slow growing. After they germinate, expose them to direct sun for limited time periods, and avoid exposing them to high temperatures. Once they are an inch tall, move them outside to the north side of your house and gradually expose them to more and more sun. They can be difficult to propagate.

All the information you need is available on the internet. Instead of asking people that may or may not know...do your own research.

just planted some saguaro cactus seeds to try and grow them in my state, idk if they will grow very well. anyways right now they are germinating in a spot that doesn't get direct sunlight as directed by many growers but i could not find any info on when it is okay to subject them to direct sunlight.

im using sunlight to germinate them and grow them i don't have any fancy lighting system and temps are fine. also when can i remove the cactus from the makeshift greenhouse im using without killing it.
