Help...I have a runaway beanstalk

[GATXBUCK]

Just like Jack I planted a magic bean and its shooting toward the clouds,but its going to bump into a 1000w hps reflector first.Day 20,4 plants...the one I'm having trouble with is the only one from seed (LA Confidential) and it has grown over a foot in the last week,towering above the other 3 and about 16" from the reflector.It has 2 main stems and the stems are thick and healthy.What are my options?This is my 2nd grow,on the 1st I had one get taller than the reflector and tied it over to the side but that cola never grew any larger the final 3-4 weeks,hoping to somehow avoid the same this time around...thanx

floor to reflector - 61" (will be able to raise it 1" or 2" tonite)
top of soil to reflector - 50"
top of plant to reflector - 15" (I could swear I pulled 16" an hour ago :wtf: )

Top it. You are in Veg, control the plant to the size you want. I purposely want short plants myself, so I don't allow them to get to tall. I LST them and top 'em. Check the T5HO vs. HPS thread for my examples, the original mother was 5 feet tall.
Mine are finishing at a max of about 16 inches, two at only 10 inches with multiple "Main" Cola's. That's why I like the T5's, they don't shoot to the sky if you keep the light close. (like under 6 inches close). I wack their heads off in veg,(I am doing 3 of 4 without topping this round to see what happen's) and tie 'em down.
Control the plant I say, don't let the plants control your space if you can avoid it. :)

One option is, grow the tall plant horizontally. One plant can become a dozen plants if you can support it with roots. That means a large pot. It can really produce and is great where numbers of plants can be an issue.

Day 20 of the flower phase OMB...not veg,my bad.I do need to learn a few tricks in veg to keep this from happening,this is the first one Ive grown from seed and wasn't expecting such a big difference in growth.Shovel,I was thinking about throwing a little stand together out of 2x4's that I could lean the bucket (5 gallon) over @ around a 45 degree angle,is this what you mean by growing horizontally?I'm pretty sure the roots would be solid enough by now to hold it up.

Top it off buds are in stems

[GATXBUCK]

Its already budding,are you saying to cut the tops off now?

Leave the bucket as it is. just train the plant over a little at a time. When the soil and roots are wet is a good time. I did this with two of my outdoor plants 2013 and they produced very well.

tie downs,bondage,training etc....can be a positive method with height restrictions.Done right can also increase yields somewhat.

I just tied the 2 branches straight down to the rim of the bucket,just cinching it snug.About all I can do @ this point I reckon.If it gets above the reflector I can hang my t5's over it.Ive found several videos & blogs on training from seed so I should'nt have this problem again...thanx for the input.
