Club 600

Ime guessing the horizontals will be in sealed hoods and the vert bare bulb,,,,how many of each are u doing if ur doing say 3 to 4 sealed hoods a 8 to 10 would take care of that and a 8 to 10 for exhaust of the room and that will naturally pull fresh air in
 
I run a 8 inch max fan on a 600 and 1000 water pulling thru carbon filter and pulling hot air from room set on low and my temps are perfect if u uses a 8 inch per 3 sealed hoods u should be way fine they are pricey but I love them wouldn't use another fan besides vortex and my room is 8x6x8

i don't think there is a fan on the market capable of cooling 6-8 600w bulbs in sequence. i ran 3 600w cooltubes in sequence with an 8" rvk fan and they were fine, if you want to run six air cooled reflectors (especially the big ones) i would recommend a similar set up. i wouldn't cool more than 3 air cooled lights from one fan though, the heat of the last bulb to be cooled would be double what the first one is.

i don't really know much about cfm ratings, trial and error is a good way to make a grow work on a budget, my preference is an over-engineered grow room that will give you no problems.

like bassman says there are a lot of variables to take into account, you are asking in the right place at least.

They are being cooled in parallel format. Each light has it's OWN fresh air intake, so each bulb receives the coolest light possible. My question is will a 2080cfm 12" Vortex fan pull enough air through each duct with a dust mushroom on each intake. :confused:

I was looking for more along the lines of "I use a 750cfm fan for 3 lights=250cfm per bulb."

I understand there is added resistance because of the filters.

All will be air cooled.

There will be 2 MH on the ceiling, 1 HPS in the middle, and a HPS on each wall. (Mounted away from the wall, of course)

I call it "The Reactor"

Just think "Open Colluseum"

Why light plants from one side, when they POP when lit from all around.

I ripped my design straight from a greenhouse I saw overseas. In this case the bulbs were bare. I wish I could go bare. But with the Lumens I plan on splashing per M2, I think I'll be happy.

1000 ft3 sounds bigger that a 9x8 footprint unless you have 14' high ceilings?
I agree with ghb I am afraid, I dont wanna steer you wrong and buy less that needed. I run an 8" fan on a single 600, def overkill, but I can speed control it and quiet it down, and it is in my 4x4x7 tent.
I run a 1000w in a 6x8x10h with a 250 cfm fan, and it stays around 75-80 with the ambient being 70*....if that helps at all.

It's actually 880, but I use the 1,000 figure to overestimate equipment. It has been my findings that buying overqualified equipment and running it at 50%, is better than running adequate gear at 100%.

Also, my footprint is slightly smaller than the actual floor, because I need clearance for the tubes so they don't set fire to my wall =)

This would be ideal, but I live in the Northwest. Pulling 2080CFM through the grow area would deep freeze my girls. This is why the lights must be sealed. I must limit the amount of fresh air to control heat, so I have built solenoid activated vents which will blend fresh air with house air.
 
Been raining all day so I've had the pleasure of catching up with the 6. Feels good haha. I really wanted to get the framing for my compost system built, oh well.

Can't remember who asked about loosening soil, but I did it all the time with a small piece of heavy wire. I also noticed wwatering more slowly helps prevent the soil from compacting... But it's always good to loosen up that crusty layer.

Bill, those purple trichs are f-ing awesome!
Dst, DANK! Hehe.

About tebow, I'm happy for him but the pats are going stomp the bronks.
Im a little nervous about the niners next week, but I think we stand a good chance at bringing the lombardie back to New Orleans. :-).
 
Add up the value of your lights, then add 20%, and then divide by 2 is how I normally work it out, but then that is metre cubed rating (in Europe I never see cfm). I think even if running in parallel 1 fan will still be a lot for 8 different cool tubes, no matter what the size. For the price of one extra fan in such a large set up (i.e splitting 4 tubes for each fan) is surely worth the economics of the extra $. Just my crappy Euro's worth, lol.

I saw a great bit of poetic graff from an artist called Laser here in Amsterdam.

"Pennies from heaven"
"Euros from hell"

I have the pic on my phone somewhere.

THANK YOU! I can work with that formula. I lived in Cambridge for many years so Metres are nothing new to me :) So two 15cm fans pumping 350CM a min each should do?

I cooled 4-600ds with one 435 cfm fan but I also had a good amount of ac. I wouldn't cool more than 4 lights with one fan though,, like dst said its a good idea to split it up... jmo
 
Purple trichs?! Amazing. It just never gets dull here. Who is she bill?

I just set up a second square meter tent and I'm using an 8" (720 cfm) inline to pull through 2 6" filters in parallel. One tent is filter>cool tube>out, and the other is bare bulb reflector so it's filter right out. It's more than I need for the two tents. So much so that I had to buy a speed control. My one tents sides were sucking right in. One thing I noticed right away is dryness. It draws humidity right out and now I'm dealing with that. Both bulbs are 600 by the way.

Heads Up. I brought up that tactic a while back. I use a metal BBQ skewer that has a nice finger loop on it. I do this after I pick up my fabric pots and loosen the dirt up by kneading around it.

What can any of you guys tell me about heating pads for propagation. I'm feeling a bit of a newbie these days but I know it has to do with the cold temps in the dark that are making it difficult to keep my mediums warm. I just had great success and I'm sure the nice temps in summer made it easy for me but now it's winter and it's a whole new challenge. Even during the day when lights are on and the air in the dome is warm and moist, the soil is still cool to cold. Anyway, I've heard regular heat pads can be risky because of the temps that they reach but they're also cheaper and more readily available so.....Any thoughts?

Terrible luck with medium cloning I'm afraid. I tried 5 times with soil plugs and blended soils...

With my NFT cloner, my water pump keeps the nutrients at 80F

I've had it jump to 90, and all 10 survived!

A roughneck container, a water pump, some PVC piping=Easycloner

I think I have the light ventilation figured. Can't use outside air, but don't need to I just learned. If I run a Vortex V series 2050cfm, that's 340cfm per bulb, which should be enough. :hump:

My friend just called me a "Hipster Douche bag" for having 30,000 lumens per plant. That's twice I've been called that now. Hmmm. Should I be concerned? I don't even wear abercrombie...
 
thank you afrawfraw but I'm talking seeds and seedlings. I have to get some going right away but I'm reluctant until I find a solution. I'm even going to hold off on using my good gear for the next run. Instead I'm going to run a dozen or so seed I pulled from a Deep Blue X JTR recently. I'm just finishing off the last of her and I'm going to miss her pine cleaner taste.
 
I used a heat mat with a temp gauge and rapid rooters with no issues germing seeds. I just set the temp to 78 and let it go. Those new roots are drawn to heat.

Oh man. Grab a 75 watt regular old bulb, a clip on/ clamp on light fixture, and a small box. I'VE NEVER TRIED IT! But heard it works great. But you do know you can start seeds in an aerocloner, right?

I know soil rocks, but for starts/seeds, you can't beat it. Heat, moisture, air.

Put the seeds in a paper towel and into a zip lock back. Now duck tape it to your thigh. When it itches, those are the tap roots growing into your skin...jk :P

The air I pull in is straight from outside thru a 8 inch hepa filter pulling in 40 deg air into the room
