Strenghtening Branches In Soil Grows Question

In hydro setups to strengthen branches one might use a silica, pro-tect, rhino skin etc..
and I'm not sure if these type of products can be used in soil applications?
I can't seem to find any threads/posts on strengthening branches for soil grows and
I would like to build up the cell wall structure of branches to support bud weight better so I am
wondering what might help in this situation? Thanks!

Try a fan circulating around. Always works for me and I seldom have to either tie or stake my buds at the end of harvest.

Agreed with above post about the circulating fan. Every leaf should have movement at some point in the rotation of the fan. It's also important to get as strong of a breeze as possible without damaging the leaves. Some times I will see burn marks on a few leaves where they were flapping against eachother in a strong breeze but the branches become so robust so its worth it. I also use silica but the proper use of a fan will make the major difference in stem strength.

silica can be used in soil. also its good to foliar spray so that the fans strengthen the stems even more~!

For outdoors, fans or wind mostly help strengthen the stalk but not the
branches so I am wondering what kind of soil application would help strengthen the outer branches
to help support bud weight? Thanks!

if the leaves are wet and the fan is going im saying it will strengthen everything. aslo more P will decrease node spacings
