DIY co2 pressure

I just made a DIY co2 recently and it seems that the pressure produced by it seems kind of weak. Is there any way to have more pressure in your DIY co2 system?

How long has it been producing CO2?
What are you using as a diffuser?
How did you make your system, what did you use for parts?
If the diffuser isn't providing much of a restriction, there won't be much pressure. This isn't necessarily a bad thing; there is less risk of a rupture in the system. If you are still getting a sufficient amount of CO2 into the tank with small bubbles, that is the only thing that really matters.
There could also be a leak somewhere in the system. Most likely where the airline goes into the fermentation container.

More yeast will also ferment faster requiring more frequent changes. Some people find this to be a pain.
Cooler temperatures will cause a slower fermentation.
The types of sugars and available nutrients will effect the fermentation rate.

If the system is new and has never fermented well through multiple batches, I would check the setup for leaks.

Ok thanks for the input! What i am using for a diffuser is just cotton and for some reason no bubbles come out from it. Although when i take the cotton out bubbles seem to be coming out just fine. When I have the cotton in i can see bubbles are still going being produce in my bubble counter. Must be a leak. also i do have two check valves one from the yeast bottle to the bubble counter and one from the bubble counter to the tank. Can that be a cause for me issue?

Sounds like you have a leak. I think you only need one check valve...I don't use any LOL try a broken piece of wooden chopstick to diffuse your bubbles they work great
