This is my outdoor grow n I’ve never grown a plant this big it’s starting to flower just wondering what to do to ensure a good harvest

Nice!! Support stakes or a trellis net would be great for that plant

It’s white widow

Looking very healthy. how long has she been in the ground....is it an auto or a photo and what's your climate like where you live.

What is your but and slug prevention scheme?

That's a bushy beast! I would be hoping/worried about those branches getting heavy and might think about adding some kind of support or cage.

Curious to know myself. As much as we baby our indoor stuff it's hard to believe these plants just grow outdoors.

Best I could offer is random plant knowledge like create an air gap between the bottom of the canopy and the ground to increase airflow and reduce humidity pockets. Very healthy looking plant though. What is it?
