I have one plant that I attempted to train and during the stretch one branch way at the back shot up 12 inches above the rest. All the rest of the branches are at at the same basic height. How do I set my light for the best par value? do I set it for the one branch or the many?

Currently I have my light hanging at like a 45-degree angle so they all get a better average par. Is this bad for the light? The plant? What other options do I have?

What kind of light? If it's an LED light, the only thing it changes is how the light pattern is spread. It will not harm your system. As for HID lighting, once upon a time bulb orientation made a difference in the bulb you purchased. If you purchased a vertical oriented bulb and mounted it in a horizontal fixture, you were asking for premature bulb failure. I'm not sure if that is still factor today. Much has changed in the last 35-40 yrs in HID lighting.

Yes, it is a 300-watt LED. Bar style. If I don't angle my light, then I get to choose between burning my one tall stem or 80% of my flowers being underdeveloped.

Many of those bar style lights are marketed for vertical gardening so yes your light is 100% safe. You won't hurt the one odd branch if you weight it down/tie it down some to make a more even canopy. Choose what you think will give you the best results with minimal plant interference.

Here's what's going to happen ... You'll even out your canopy ... all those nodes will begin to grow straight up towards the light. Those buds get better light and develop faster/thicker and fuller. I will roll the stem between my fingers to soften it and then gently bend it until it buckles. I do this every year in my greenhouse although not so much inside.

It's much safer than topping during flower and the chance of overly stressing the plant is almost none.

Also once its 90deg horizontal you could bend a bit of fencing wire 90 deg to support the branch.

The only risk is what happened to me last grow. Botrytis can enter the plant through the wound. Not saying it will, but it can and does.

True ... and outside in my greenhouse ... insects, mold, wpm and other pests could show up even with the best of preventative care. There's much to look out for but I still would either tie down or super-crop and support to keep them in my grow space. There's always some risk. I've even broken plant material completely off in my lst attempts. In my eyes, done correctly you'll be successful far more than not and is worth the risk involved.

Yeah just bend it over. I'm doing this right now in flower as 1 plant got too big. I'm supporting with a little ball of tape in the bend with a very loose piece of tape holding the ball. It's looped so it's not touching the back of the plant. Very easy to remove after 4 or 5 days when the plant recovers. Just cut the loop and pull away. I just removed them yesterday or I'd post a pic.

Try to spread the bend over a larger are. You don’t have to go straight to a 45.

I think someone already recommended massaging the stem to soften it.

You can even mist the area a bit to soften it. Be careful obviously

Seems to be easier a few hours after watering as opposed to before
