DIY humidity dome for seedlings

I think something is dead wrong with this method.As an aquarist, we do emerse grow method (as known as "Dry Start") and use our tanks for that purpose, sealing the top with cling film (stretch wrap) BUT with a very important modification: After sealing the top completely, we tear a little bit from the rims of the tank just to allow the plants to get Co2 from the air as the Co2 is one of the most important variable on plant grow because it is required for photosynthesis process. You need to provide enough Co2 for your plants but sealing the tupperwares like that will cause Co2 to drop ciritical levels or even completely finish.I would suggest to drill some holes on the top of the upper tupperware so the plants would always have fresh air (both O2 and Co2). Ofcourse this will cause the humidity to drop on the other hand but it can be by-passed by moistering with a spray and/or adding water to the bottom as needed. My guess would be doing so once a day or even once for every 2 days would be enough if the environment temperature is less than ~26C (~79F).By the way, I have serious doubts about the transparency of those tupperwares. They don't look like they will transmit the light without emitting/changing any spectrum/temperature. Even our glass tanks (made of extra clear glass instead of regular glass which means much, much more transparent than regular glass) loses some of the light, I can't imagine what would a plastic do - or don't. And again, this will also effect your grow rate in bad way, too.So, after all, maybe it's not the best idea to use tupperwares to make a DIY humidity dome. I would definetely go for plexiglass if I were to build my own humidity dome.
