nice tec what do you mean tie down ware not cut in tent cost cash any more ideas ?
Do not cut holes in your tent. Since you are in a tent and didn't use a screen to keep the plants short and bushy and now have nothing to tie them down to here's what you can do.
Get anywhere from 4-8 buckets ..... 3 gallon trash cans from walmart are like $2.50 each. Drill several holes (about 1/2" diameter" in the top of each... just under the rim.
Fill them 3/4 of the way full of either water or sand (something to weight them down... but not something that will attract bugs.).
Place the filled buckets on all sides of plants.... run yarn around the top of the plant stalk and back down through the holes in the top of the bucket.
Gently pull the plants down ...... just a little at first, you don't want to break them. Then every couple of days... adjust to pull the plant tops over a bit more. Eventually you should be able to get the plant close to 90 degree bend.
If this doesn't make sense... say so and I'll provide a diagram
