Hi, I want to connect a 100x100 tent with a 120x120 tent and use for the output either RAM Inline VK Ø125mm 375m3/h or TT 150 Fan 467 / 552m3 150mm I have a 100mm and a 125mm inline RVK fan available for intake, can this work successfully, connecting the tents themselves by 150mm airduct?

I guys I’m planning on buying some sort of controller to help maintain the temp in my tent. I’ve got a 600w hps. A 150w extraction fan in 6 inch duct. And a 2kw heater outside the tent. Any suggestions on best set up to maintain temp? Thanks

I have a friend who is doing their first legal grow in America, however his internet has crashed so he has contacted me to try and find a solution. The Problem is heat! It is a stealth cabinet grow currently with a 125w dual spectrum for 2 plants in 5l pots. They understand that this might not be the best set up but its what they have. Apparently temps usually sit around 85'F or 29.5'C which is quite hot on its own but temps have reached 111'F or 44'C on the odd occasion. The temps are being measured at the average height of the plant, Apparently they are around 2 weeks old (from sprouting) and are an autoflower strain. They haven't browned or discolored and are still a health green and growing daily, however some of the leaves are curling up at the edges and some apparently seem to be almost spiraling around ( not curling under but twisting sideways) not massively but a little. There are 2 80mm PC fans ,one intake and one outtake, which more than cover the cfm needed for the space. So what do you think he should do to reduce the temps? Add two more PC Fans? Also if they were do do this, roughly speaking one fan is in a bottom corner and the other is in the opposite top corner, would the two extra fans if they were to be attached on the opposite side of the cabinet be placed so that the intake are both at the front and outake both at the back or so that both intakes are say bottom right on each side, so from the front one would be near the front and one near the back? Add a PC fan inside to increase circulation? Reduce light hours as they are currently running 20/4 - 20 on and 4 off Also can anyone recommend any threads about building scrubbers/ carbon filters? Would a carbon cooker hood filter work? As apparently it has started smelling not of full flower but a smell they would like to remove. Thanks in advance for any replies!

Good morning fellow farmers I'm in the process of upgrading some elements of my grow room and would really appreciate some advice on what works and what doesn't. Here's a photo of the room, and a diagram of the layout as it stands now. And the propopsed upgrade/adaptation: I will be moving the tube heater into the double vents on the right, placed in the passive intake. I've also included a second clipon fan clipped in the most convenient place - the almost dead space between the CF and the walls, and the right side of the door, which is convenient. Can anyone see any problems with the air flow setup this way?

Hi guys, It's my first grow and I'm in first week of veg, I think ha ha. Basically I'm trying to find out whether my airflow set-up is correct. So here's what I got..... 6 plants in a 1.2 x 1.2 x 2.0m tent, growing in coco under a 600w hps. I have a 4" intake at 187m3/hr or 110cfm and a 5" outtake at 280m3/hr or 164cfm ( i think conversions are correct) Will the above fans provide with correct air exchanges? My temps are currently around 26/27 celsius, humidity is on the floor, the digital meter just has 2 horizontal lines on it which I assume means zero . Struggling to get my head around the airflow and the only examples I can find on the web are for completely different/more advanced set-ups. I've always been a believer that anybody can learn anything - if you can't understand something then it may be because somebody isn't explaining it in the right way. Can anybody give me a quick tutorial that is easy to understand......? Many thanks in advance
