This is my first run wiht the cheese and boy does she grow different from anything Ive ever run before. Absolutely must train, trim off lowers, and lollipop the branches. Some of these plants remind me of the crazy statues the mom made in Beetlejuice hahha
Rock solid nugs on these plants.
buds so thick they're creepin up the walls

Here are a few cheeses in coir. Used the rest of an old bottle of FF grow big. now they are on the maxi/ kiss diet.
Never really trained and trimmed plants like this before. Hoping all goes well and I see that good stretch. Still vegging now but thinking Im gonna flip this weekend. Diggin this coir action for sure.

So Im startin to take down tents as the last couple things finish up, gettin ready to set that whole room up, but Im havin trouble figuring out which fans I need to purchase, if any.
Im wondering if it makes more sense to use one super powerful fan on the exhaust end of a duct run or if multiple smaller fans throughout the run are more efficient.
Also, If you have multiple fans, do they have to all be the same CFM? It seems to me that if i had a 1500cfm exhaust fan and a 600cfm intake on the duct run that the intake fan would actually be limiting the air the larger fan can pull. Is this a correct assumption? Or do the cfm's magically get added together?
Ive been calculating according to the Ventilation 101 thread, and since I will be running somewhere between 3200 and 4000w, I need between 1000 and 1300cfm for a delta T (temp rise above ambient) of 10F. There will be several bends in the ducting so this needs to be accounted for.
Should I go with a 1800cfm fan (or larger?) on the exhaust, or go with 1000cfm on the intake and 1000cfm on the exhaust?
One thing that caught my attention in the vent 101 thread was the mention that more than 1 air exchange in teh room itself per minutes stresses the plants? This is really news to me, as I was always under the assumption that if temps and humidity is in check, you cant really move too much air. Sorta like light.
With this in mind it seems more prudent to run a super high CFM through the duct run to try to keep the temp rise as minimal as possible, so I can exhaust the room with a simple 6" 450cfm fan, for a single air exchange every 4-5 minutes (14x18x7 = 1764 cu. ft.)
What does everyone think?

Cheese in coir, gettin flipped today. Curious what to expect from the stretch. I think I may end up spreading those 5 plants out between both lights in the 5x10 tent. Got a shotty trellis up to help me visualize but they are gonna need way more support for sure. Floppy bitches them cheeses.

One of the cheeses is showing some funky leaf spots and such. I have to admit I havent been ph'ing anything, just dumping half a teaspoon to a full teaspoon of maxigro per gallon and hittin em up between 1-3 times a day by hand.
The one plant showing issues is also the biggest one. Since no other plants are complaining im gonna assume its just general hunger, but Im also gonna finally dust off this ph pen

Decided to transplant that one showin issues. One of those bottom watered/earthbox style pots. They do great with add water soil mixes, lets see how it does with some coir.

Looking good bro. Stay focused and methodical. Setting up multiple rooms can get overwhelming...
Last pics are hard to see on my phone, but might be a calcium issue. Are you getting any hooked leaves on new growth? I'm getting the same spots in the middle of my plants. Think it's under control as of today.. I hope!
Keep up the good work man.

A larger exhaust fan will pull regardless to a point... the intake fan is almost worthless in this situation beside the restriction it produces on the exhaust fan
I did a TON of work on commercial ( NYC high rise office buildings ) HVAC supply and return fan systems (+100000CFM fans) ...... if you have any questions regarding fan issues feel free to shoot me a PM.... might take me a few to respond but I will definitely get back at ya

Your gonna need a bigger fan with bigger duct work. Or multiple exhaust fans and multiple intakes, just for the lights. I know from experience. I have 3 1000's and three exhaust fans, the 450 cfm one's, actually I think they are rated for five something. The bends in the ductwork are gonna slow things down too. With al those lights it's gonna get hot in there with massive air movement. Changing the air in the room itself twice a minute is also a great way to keep things under control. This is just my 2 cents from what I've experienced.

Didn't really use the screen SCROG style, its more there to slip down after stretch is finished to support the buds. The plants were vegged up in another room. My biggest issue right now is developing an even canopy when not vegging in situ, so to speak. Its way easier for me to train an even canopy when I veg the plants in the same place they will be flowering. Gotta overcome that.

And here are some shots from the fun little CFL cab with a 4 in booster fan and 4 23w CFL. If only all my plants were so healthy lol
