I like your veg cabinet, very nice work. How's the temp holding with the enviro close to your propagator? The closer the better of course. The solution with two fans inline to create more pressure to extract through the filter is a good solution. I just wonder how much do you extract not to create an overpressure in you cabinet?
It doesnt often go over 28c now its in a cooler room upstairs (radiator off) window open a little.

I would certainly try to do something about the extension socket. A growroom is a humid room by definition, but you could easily solve this by boxing it and drilling a few holes in the back of your cupboard for ventilation (cooling of your power supply).
humidity doesnt go over 50/60 Im letting the plants create the humidity naturally, I only use it for the first 3-4 weeks from seed anyway, I can only really fit ten 5" pots in it under the envirolight anyway so use the flower room when I pot up from 5" until they rooted out there final pot then switch to 12/12

Adding a small computerfan to your envirolight blows away a lot of heat, could be a nice addition to your setup.

I was just wondering about your cooltube cabinet: Do you intake air from your cabinet and extract that through your cooltube? It's more effective to keep your cooltube "closed loop" - take in cool air directly from outside and blow it through. Less resistance, less humidity and the final advantage: no filter needed for the cooltube! A passive intake should be enough, a double bottom with holes in it might even give you a better and quieter air flow through your cabinet. I use two RK125 fans for a 1,5 m2 room and a 400 ánd 600 watt tube. One fan for cooling the two tubes (inline) and one for extraction. The intake is passive. The cooltube system is a closed system, so I don't loose any power from my fan there extraction through a filter and the system is nice and quiet.
Im taking the cooltube out today and putting in an original adjustawing (with heatshield) as this will light my space better (135cm x 75cm) I should be alright with the fans I got right now but if needed I can upgrade.

You can prevent a lot of noise from your fans by hanging them in rubbers.
Did this the first time, then ripped it all out and concentrated on getting the temps right before I was concerned about noise (its very quiet anyway) Now that my first grow is finished I can tinker some and thats one of the things Im thinking about again.
Edit ** and here's a quick photo of her in action, I think they are chronic in there right now (could be white russian) there is some confusion over what beans i popped. Temp is 24.6c and rh is 46%
