Light question for outdoor grow.

[Gato420]

My question is just how much light does cannabis really need to flourish? I have always heard light light light when it comes to growing buds. However, I have a clone outside in a spot where it gets very little direct sun and is flowering well. I have my eye on an outdoor spot that with a little help should provide a little direct sun with lots of bright filtered light.

Would it be worth the effort?

That's a good question, friend. I use the Sun whenever I can because I love the price. To flourish, one needs at least 6 hours of direct sunlight from any direction. If it is a long-flowing sativa, it needs at least 8 hours.

Expectations are hard to judge. Direct light here, might not be as good as direct light their. I'm in the UK, and have productive sites that the book says shouldn't be. I even have shady spots on sites, that are better than the less shady ones. Because the shorter light hours bring about flowering in warmer weather. Even if it is by just a week. I have had new sites where come Autumn the sun didn't get high enough to clear tree's. They were not the best, but with UK expectations, I didn't mind.

6-8 hours is often said, but I have few sites open to the sky for that long, once the sun is lower in the sky. I don't even have 12 hours light anyway.

I might settle for 4 hours in those last days, and still be happy with a site. They need to be morning hours though. Experience shows this, but there is also some logic behind it.

More light means more yield.
You can get a plant to finish with less light but buds will be small and looser. Quality (smell, taste, potency) should be still be good as it's mostly determined by genetics.

How long are the internodes? If they get large in veg it is trying to reach the light.

I actually got the idea from watching those guerilla grower guys in the UK, they use Google earth to find space along the interstate systems to plant. They were using spots I didn't think optimal and getting great results. This plant I have was looking great until a storm broke her over. Scotch tape and a stick to the rescue! She's looking good but will never finish outside here. Just a test anyway.

I read in an old grow book years ago to plant on the west side of openings so that morning sun would dry the dew off buds.
