Extending substrate colonization time for a trip

Will be gone about 23 days soon and want to take a shot at allowing a substrate to colonize without it reaching 100% colonization way before I arrive back home. Got nothing to lose other than a substrate wasted. I'm thinking of going with a high spawn ratio to increase the time.
Added later for clarification: I'm doing trays and not a monotub.
I've only done cakes so far and if I was not taking this trip I would be probably use something similar to hpoo 50%, verm 25%, coir 20%, worm castings 5%, tablespoon kelp meal and of course gypsum, since I have this gathered already.
But right now I'm leaning at just doing a coir/verm/gypsum substrate with something like a 1/10 spawn ratio due to contamination risks that a slower colonizing substrate would have, and think it would best to go with a less risky substrate that I properly pasteurize using the method in RR's video.
I've read lower spawn ratios only take days off of colonization usually, but what about something like 1 part spawn to 10 parts substrate? This might take about 3-4 weeks to colonize maybe? Longer is fine, I just don't want it reaching 100% colonized in 2 weeks or less.
Any input in what other peeps would do if they were taking 3 weeks away and wanted to colonized a substrate during that time?
-------------------- A bit expensive but the largest clear tote I've found. Great if you want a large SGFC that can easily do both trays and cakes. If you decide to go all out on a SGFC, be sure to get coarse perlite. It keeps it cleaner and allows better FAE and humidity.

With bulk substrates you wont it to colinise within 2 weeks. Thats the window you get when you pasturise.
You could sterilise and spawn in sterile conditions.
But remember, that 2 weeks is the colinisation time and not nessesarily how long it will take to fruit, it could well be 3 weeks maybe a little longer till its actually ready to pick.
I use a 1:2 spawn:bulk ratio it usually takes 10 days-14 days to fully colinse though the temps have really risen here so it might be quicker now.
I wouldnt go past 1:5 , the longer it takes to colinise the more chance it has for contams to take hold.
IME from MS 1:2 has been around 2 weeks, with a few tubs that were a little too wet taking longer. If your doing monotubs i wouldnt worry so much about being away for a while. likely that your come back to a tub ready to harvest maybe spores everwhere.
id probably go with 1:5 at max make sure your substrates moisture content is absolutly right, and mix up your bulk and spawn the day you go.

Oh shucks... I left out an important part. I am doing trays with my SGFC and MS. This complicates it a bit I guess, because a mono would be best in my situation, but I'm not going to be doing mono's in any foreseeable future.
So even with coir/verm/gypsum pasteurized correctly I would be running too much risk extending the time? If it became contaminated then no big deal... but if the odds are huge in favor that it would contaminate then maybe it wouldn't be worth it.

I'm just a noob but I'd keep the spawn ratios normal, let it colonize normally for a few days to recover and put in the fridge to slow down growth. This will help keep the contams from getting a foothold. A proper pasteurization will be important as well. I would just use coir and verm as my sub however, you want things as contam resistant as possible.
Just leaving it would be kinda risky IMO, as you don't really know how the genetics are going to perform. If you are using ms you might end up with some super aggressive genetics and come back to find your sub colonized, and fruiting, with a big spore mess and nasty skinny fruits.
I would wait to see if any TC's had any opinions before doing anything however.

Looks like my spawn jars will make vacation time and I'm still leaning at a 1:10 ratio on a coir/verm/gysum substrate and shooting for a 3 week colonization time so I will have something close to done when I get back. I think 1:5 would cause it to be fully colonized too soon before I get back.
My reasoning is...though not contamination free, I'm living in a fairly new condo on the 4th floor, in a desert climate that air comes not far from the ocean. I also got a pretty high Merv rated furnace filter. If 1:10 would work for anyone I would think it would be me due to I think I have less contamination risk.
True...Mono's might be better, but I'm sticking with trays and an SGFC.
I will only waste one quart jar of spawn a brick or coir and some verm and gypsum and my time, so if it fails no big deal.
I'm too new at this, so 1:10 ratio maybe take about 3 weeks? I guess I already know the answer...too many factors that would influence it, but if I get back from my 3 week trip and it's not contaminated or have mushies that busted the top off the tray and dried it out then it will be a success and allow me to fruit close to when I get back.
