How many clip on fans for inside the 32x32 tent?

[The123321]

I am new to growing. I am looking at the 32x32 tent with the 240w kingbrite quantum board with the ac infinity 6" fan with filter with 2-4 auto plants in coco coir in 3 gallon fabric pots for the perpetual harvest to plant the plants a few weeks apart to where you could harvest 1-2 plants every few weeks on there for it.

I am now looking for clip on fans for the tent. What size do you recommend? Do you have a brand you recommend? I want the fans as quiet as possible. I do not mind paying a little more for a higher quality fan that is more quiet. How many do you think I would need in a tent like that? Do you think I need 2 clip on fans or would 1 be enough in the tent on there for it?

I wouldn't use them. They are big for such a small space. I would look at computer fans. Two will spin that air around like a whirlpool. Without casting much of a shadow. They will be a lot quieter to. The clip fans are cheaply made and will vibrate anything you are likely to clip them to. I would be looking at a couple of 120mm case fans of the 2 or 3 wire variety. So you can get a 3-12v psu to turn them up n down. You can add more as the mood takes you. Like some on the floor, sending your fresh air up where it's needed

Edit: My micro grow is using no fans for my canopy at all. Just floor fans, to ensure my fresh air gets everywhere.

Thanks. Do you think like 4 pc fans would be strong enough to move the air around enough in the 32x32 tent? I have like 4 pc fans with the control on there for it.

I have a 60mm fan in a 3x2. There is air crossing the tent, hitting the other wall, splitting left and right, then coming back along the 2' walls, before turning the corners to meet at the 60mm fan again. That's one 60mm fan, setting up two air currents, moving all the leaves in a 3x2. I wouldn't expect to flower like that, but little fans can make a draft some distance away. It's making them pass the air between them that really gets things going. Like rocking slightly in the bath, eventually chucks the water out.


Obviously it was a bit too intense for the one in the middle, but I will win it back

Thanks. That 1 fan moves enough air for the grow in the tent? You mentioned you would not do it in flower? Why? Would you think that 4 of the pc fans would be enough to move the air enough in the 32x32 for veg and flowering in the tent on there for it? What tray is that you have in the bottom of your tent on there for it?

That fan is fine for now, and as the plants pack out I won't change it. The lights have fans, and are turned to assist each other. It's not as effective as the unrestricted 60mm but it will circulate. Once in flower you want to be a bit more definite about your air flow. The risk of high RH leading to mould, means you don't want any air sat about for long. Which means having some circulation everywhere, and extraction to get the air out, not just round. Plants are made of mostly air and light, so you want a fresh supply getting everywhere. It's why I catch my fresh air at source, and send it up through the plants, with no real interest in circulation. I want fresh air though my plants once, past my lights and out. Nobody else really thinks like I do though and your 4 pc fans should easily pass the wet finger test.

I use 6" clip fans in open rooms, and I'm never happy about the space taken. You really don't want them. 4 average pc fans will move just as much air, with much better control and less noise.

The floor is known as a gravel tray. Sometimes a garden tray. That one was 55x120 until I took my saw to it. If you look closely along the left hand side, you can see it's not quite right. But it's set to drain to the right hand side, and still a work in progress. It's not actually on the floor, or a table. It's on something like two wooden shelf brackets. I think I have..


That's basically a flower and veg space, with enough floor space to be able to move things around, and reach the entire flower area if I go crawling

Edit: Don't be fooled by the carpet. You are looking in a tent. A luxury carpeted tent. With rubber crumb underlay, and foam underlay, and 10mm jigsaw like foam-rubber workshop floor tiles. Under my top notch carpet. Because... Luxury tent

Thanks. I think I may try the pc fans then if I need more air flow I may buy a different fan on there for it.
