fans

Hey guys I got a 1.5m x 3m tent I’m running rhino pros, 200 out and 150 in but the tents negative pressure is sucking in so hard. I don’t know if the fans are too small for the size? I’ve never had it suck in so hard but I’ve never used a tent this big. its clearly sucking out more than...

Okay, probably a stupid question. Buuut, if I put a 6 inch fan with a filter on it on a 4 inch PVC pipe about ten ft long, would I be able to get slightly more cfm through it than with the 4 inch fan? I'll have an 11x6x80" room with two 3x3s in it, they will have a 4 inch fan and filter pulling...

Hey quick question. My seeds have sprouted and have their first few leaves and it’s been about 4 days since they sprouted. I’ve heard from a few people that I should turn a fan on to let the stem strengthen. Just wondering at what point is this usually recommended?

Wondering if a plant is still growing big during July in SoCal. Growing outdoors & Looking for a strong growth. seems to be growing slow. Alaska Fert LST In sun all day Just placed in a 10gal container Starting to feel like plant will not grow big.

So I'm using a grow tent now. Figured I'd give that a try. However, before I make my switch into the tent I'd want it set up properly. Trying to decide. For air intake and outake if I need a 4",6" or 8". I got a good size dehumidifier, I'll be getting a carbon filter soon enough. I go t some...

hi there, about to move my plants into the grow room. ( they are 2“ - 3“ tall). Do i need to run the exhaust fan, the oscillating fan or both?; just figured that, because they are so small I could save myself a few pennies by not running the fans for a week or two... RW :peace:

Hey Everyone, I have a room built within a room as my flower room, it's approx 3.5 feet by 4.5 feet and 7.5 feet tall...as you can see from the attached pictures, i have a fan vented out near the top, next to the entry (figured hot air rises so higher up would be better for exhausting the warm...

So I have a 9 x 22 x 7 basement I will be setting up in the coming weeks ... Most likely two 4 x 4 or 5 x 5 flood tables, but my main question concerns my intake and exhaust fans. I'm not sure where I should put them. Eventually the entire 9 x 22 part of the basement will be covered in panda...

Hi, i'm planning my new setup but i'm confused about the ventilation. I will be using Samsung LED's for light, probably 1-2 plants scrogged, filter, 2m of extraction tube and ideally passive intake. 1) How much airflow (m3/h) for negative pressure do i need? Secret Jardin suggests only 60...

I'm new to RIU and have done a bit of digging but have yet to really come across a thread that lists some basic 'rules of thumb' for growing.. most seem to be categorized for the newb or seasoned grower. I just want to know some of the basics and have as many together in one thread as possible...

Hey, I'm going to be converting a cupboard space under my art desk to start seeds and for clones, the space is a triangle shape approx 30"x30"x40" aprox 2.5' high. I'm wanting to fit 3 pc fans, 2 for out take and one intake. Would these be sufficient for that kind of space? I want to have 2...

So I just got a small 4by4by8 and need to see ( I'm a visual person ) some set ups with fan, venting, carbon filter etc. I'm having trouble grasping that the weight of the fan can be supported by the grow tent. Appreciated in advance

Hi everyone. I want to start a fan on my ladies but I'm afraid of drying them out. Current humidity only 25. Any advice?

Hi! I have a quick question about fans-I've read a lot about several types of fans for different purposes, but I'm trying to keep it pretty simple-I don't want a lot of things running especially when I'm out of the house. I have a 3'x3'x'6' Grow Tent, 400w MH/HPS, and Stealth is not a concern...
