hahaha sleep in your tent. lol funny.. well if you want to add co2 to your young ones i would start by everytime you are working with them start talking to them since we all release co2 when we exhale. i do this all the time and they love it when you talk to them, i mean cmon its a living thing thats my way of looking at it. And another thing i would do which helps out as well is get some dry ice. A lot of people will say to boil some water and then put the dry ice inside and it will release a lot of co2. but the way ive done it with same results is that i would just get a small container or dish or whatever you want to place the dry ice inside, then i would just simply put it behind a oscillating fan or regular fan that is pointing to the plants and thats it. just make sure the fan sits higher than the plant does and that the container you are using is at the top of the rear of the fan that way the co2 will fall on top of the plants when its blowing. i do this every 3,4,5 days and it works very well.
