GreenVision Posted July 15, 2023 Author Share Posted July 15, 2023 @LK1 I have actually looked into those mate. TBH I'd have liked to go that way, I prefer the minimal side of things. The V4 Enviro just has it all in one unit, plus the new 4 socket setup, I cant turn it down. Link to comment Share on other sites More sharing options...

TMs are couple of hundred yeah and then add on the adapters for light control and humidity control but the enviro V4 is 350 ish and won't control my dehumidifier the way I need, it's the way it goes I guess Link to comment Share on other sites More sharing options...

Summer in a loft is a nightmare, I'm going large so if I needed it then it's there. The passive intakes are a precaution, if the outtake exceeds the intake it will throttle the intake fan and could burn out the motor. Especially as I'm going a fair bit larger with the out than the in. I think I'll have to email GAS. Its quite a technical question and I think there may even be a way to programme into the controller which fans it is and have not let the positive pressure ever happen. I use a smscom twin controller and plug in the in and out fan/filters and set the temperature but in the loft you will need a heater to keep your temperature up its hard maintaining your temperature in the loft and you will have a lot of electricity costs for heater I used a haven temperature control electric radiator but it was costing me to much to run so I have moved out of the loft and I now have 2 outfans and filters and 4 in fans as the room is 14ft x 12ft and I am finally getting temperature control and humidity its nor easy but the temperature is really important for getting good results happy growing Link to comment Share on other sites More sharing options...

I figured it would be better to spend the money correctly fitting out the loft rather than doing it half measure and paying to keep it warm / cool. Full roof insulation and board, uprights and two ends all insulated and boarded, loft floor will be freshly insulated and floor boarded. If done right the loft will be able to hold its own heat in the winter without any issues, cooling in summer will be more challenging, but I have a 3600m3 p/h 12" fan so I got that covered too. By the time I'm finished it'll be as warm or cool as any room in the house. The original question was about the technical side of keeping a negative pressure with a different sized intake fan. In a tent you can usually gauge it by the sides pulling inwards, so even if the maths was wrong or the controller didn't match the numbers between the two fans correctly you could still look at the tent and say to yourself its got negative pressure. However in a room the size of an entire loft with solid walls Im relying purely on the maths / controller, I'm at the mercy of it working correctly. Since posting though I've done a fair bit of research, made a few calls to grow shops etc. It does look like the GAS controller is the way to go. According to the company the controller will recognise the fans on some level, and if I programe it correctly it will handle the negative pressure at all times. Also, I intend on having two passive vents, as 3600m3 is a LOT of air movement. The intake fan will feed the room its fresh air, but as the room is going to be all but air tight I'll need some release in case the outtake is pulling a noticeable more amount of air in that the intake is feeding, in this case the two passives will feed the exra air needed. If I can feel any air coming "OUT" of the passive's oncve the system is running then I know I have positive pressure. Also these will at least give me a heads up of any smell leak rather than it leaking outside the house first. Cheers. Link to comment Share on other sites More sharing options...
