We punched some 1/2 inch holes in the other side of the lid and you can feel the air coming out of them when the fan is in place. This will ensure that there is always plenty of fresh oxygen in the rez for the waterfalls.
Still need to finish taping it up and hopefully I get an answer back on if the rez temp being so high is going to be an issue- if not we'll need to install a probe chiller or even two of them. I've heard of people getting away with higher temps than this thing will see using this method so I think he'll be fine for the first run and then he'll install the chillers after the harvest. If he can get the money together before that then we'll install a chiller just because I know it's beneficial.
Anyways thanks for looking, I'll update this again when the plants are big and beastie
