About Cotton Seed Hulls Wetting & Pasteurization

I have few questions about cultivation oyster mushroom on cotton seed hulls supplemented with wheat bran.I got some experience about wheat straw based substrate but in order to get higher yields I would like to use cotton seed hulls. Cotton Seed Hull (%93) - Wheat Bran (%5)- Lime (%2).OR do you have any better formula for that.
According to my researchs on internet it says that I need to soak up cottonseed hulls 3 days in a drum to get required moisture level and spread it to somewhere clean to squeeze excess water overnight.Then it says I need to pass to the pasteurization part.But I'm using chemical pasteurization (formalin (125ml) & carbendazim (7.5gr)) for 16-18 hours.What I'm wondering is ; do I need to soak up with chemicals for 3-days ? OR I just soak up in a pure water for 3 days and pasteurize it again in chemicals for 16 hours again ? 
The other question is for the wheat straw based substrate pH 6.0-6.5 is enough for mycelium growth.What about for cotton ?
My last attempt for cotton seed hull was a big disaster.I just soak up the material for 16 hours with hydrated lime pasteurization but a week later I found out that it squeeze all water inside 
If there is an exist thread ; sorry for that.
If anybody answer those questions ; I really appreciate it. Thank you in advance.

Fucking shit man get rid of the carbendazim, also forget about wheat bran unless you're sterilizing in bags. Cotton seed hull and straw 50-50 worked for me with lime pasteurizing.
"Studies have found high doses of carbendazim cause infertility and destroy the testicles of laboratory animals.[5][6]"

I'm not actually pasteurizing in bags.Firstly I pasteurize then I start bagging 
"""""Studies have found high doses of carbendazim cause infertility and destroy the testicles of laboratory animals.[5][6]"""""
Thank you for this information , I didn't heard it before.I'll not use it anymore.
So you mean that if I mix it 50/50 & use lime past. method is it enough to soak up just 16-hours or 3 days for getting enough mouisture ?

If you are lime pasteurizing, you do not need to let them soak for 3 days. I used to soak csh any where from 8-12 hours and had to let them sit out and drain for almost half the day because they were too wet.

Thank you very much for this information.What about pH level? Just ilke for straw based substrate, do I need to keep pH above 10 by adding more hydrated lime ? Straw was lowering pH around 6.50-7.0 .Does cotton also do the same ?
After the pasteurization I can add gypsum at which rate? Up to 5% ?
Lots of questions in my mind

what Drake point is, if you use wheat bran then you need to do sterilization process, not just pasteurization or soaking process
