outdoor growing

Yo what's up alright well I was wondering well I plan to grow around 30 plants outdoor but I own a 50 acre orange orchard two question one do you think the trees will affect the plants in anyway and how bad will it smell

Yes and Yes....Trees affecting the plants? I you are growing dual crops (under or in between your rows) it will affect sunlight and your spray with also affect the plant.

Depending on the strain..it will smell. a little or a lot.

The only way the trees may effect the marijuana plant is that they could block out the sunlight lol. Marijuana smells, odors can travel quite far with a strong wind, especially when plants are in full bud, if the plants are very close to the orchid, and you have workers on the orchid, I would think twice before planting close to it. But 50 acres sounds like you have a lot of land to work with, I assume there would be somewhere on your property to easily conceal 30 plants or more.
