I appreciate the kind words brother. My confidence in doing this experiment comes from seeing the resilience of this little plant over the last 35+ years of growing. These ladies respond
extremely well to stress, hence all the bending techniques that are out there. I always bend, almost in half, the lowest part of the main stem in all of my plants, once they have 6-8 nodes. This creates a thick "knuckle" in the base, due to the plant rerouting the water and nutes around the bent/damaged part of the stem, creating stronger branches with larger flowers. This pencil thing seems like a much more extreme version of that.
I was also thinking of your problem of pencils being to large to use on your plants. I have a
free solution for you; not even the cost of pencils. I always dry out and use my harvested untrained plant skeletons as substitutes for bamboo stakes. I decided to save the trimmed side branch remnants to use in place of the pencils. This would work for smaller stalks very well. I just used a pocket knife to gently push through the stem, just until maybe 1/4" of the tip comes out the other side. I then use my closed/locked shears, inserted vertically. Once I get to the section of the shears that is as wide as the small piece of branch, I turn the shears horizontally and insert small branch piece. Didn't really use any tape this time because you can kind of see where the stress of the tear stops. I was feeling so confident about it, that I did a whole tent. Here are a few pics for you.

One more thing
@Equatorial. I forgot to mention one of the main fixes to apply to your dwc.....Heisenberg Tea. It is a miracle cure! I used an old sock as a tea bag. I added 1c wormcastings and 1c compost to the sock. I added 2 Tbsp unsulfured molsses to a little warm water to dissolve, and add to the 5g bucket. Bubble it for 48 hours. Add 1c tea per gallon to your res. It promotes crazy root development, and overall wonderful plant health. People will say that you need to buy specific bottled products specifically developed for hydro, but not true. I won't ask you to take my word on something so crucial. I have provided a link from a professional.

Here is a simple tea maker.

Hope this helps you grow some trees brother.
