No Brains, Full steam ahead

[Weed Killer]

After my last attempt I decided to build a new room, the specs are
5 x 5 x 8 lined with orca
Sentinel HID-2 timer
2 x 600 lumatek running eye horti’s
6” 435 cfm fan, full speed, passive intake
48 3 gal root pots filled with 1/3 GH mixed brick 1/3 chips 1/3 large chunk perlite
blumats feed with a larger version of my pump and accumulator
GH 3 part

New pics, sorry about the lousy first ones

My second coco and first sog, bit of a challenge, have tried hard to kill the babies but they pulled through. I don’t know how people hand water. I’m to much of a space case.

no need to apologize bro and do a search for 'bobblehead', then check out his 'bobblehead overtakes' thread, i think you'll like what you see.

2x600 in that room looks like a lot of heat, how do you handle it?

 

[Weed Killer]

For the heat the lung room has a swamp cooler and the 6” fan is rated at 435 cfm so that should be two air changes a minute.

The temp inside the room is 81, and the lung room is 74, don’t know if 7 degrees is average but that’s what it is.

Was thinking about putting another inlet don’t know yet.

HY BRO , CHEERS FOR THE CAB THAT LOOK PROMISING!!!
VERI interesting project, ill be watch this one!!

 

[OrganicOzarks]

Looks awesome. For that size space I bet you can get retarded yields. I will be watching this one for sure.

 

[Bush Dr]

Your exhaust is OK, but IMHO you should put in an intake fan at least 50% of the exhaust

I run 2 x 600 and had all sorts of problems until this was sorted

Blumat is short for bobblehead

 

[bobblehead]

lol... you guys... If you're there every other day for the first week or 2 to check on the blumats, they're great! I'm having all sorts of problems with them right now cause you can't just set them up and leave them for a week and expect everything to come out perfect...

weed killer- you don't have any saucers under your pots... Have you had trouble with runaways? I found that if the runoff just trickles out the bottom instead of pooling in a saucer to be reabsorbed saturating the pot... I have flooding. I also found that with the feed tubing run horizontal, I get air stuck in the lines. I'm made changes so the feed line runs vertical so the air rises up to a main horizontal supply line that is purged 24/7 by having the end of the tube go all the way up to the ceiling.

Brains before balls Weed Killer.....lol.....and yeah....Bush Doctor nailed it with yas needin an active intake fan on a speed controller so as to maintain negative pressure in said growspace for no smell leakage..........but....

My rooms ran in the low-mid 80`s for the most part with 70% RH though and ran well....Your 7 degree lung are/growspace temp variance is rockin though.....Just remember in tight spaces lights off temps and humidity are the biggest concerns to prevent airborn nasties from formin.......and.....

Bobbles is the standard of the industry here with stacked levels of plants runnin blumats cuz nobody`s done it on the public forums , and shit needs dialed to perform properly as he`s so well documented his problems with vapor/vacuum locks from air bubbles developing in the feedlines......anyways......

Waitin fer good things and I`m over here on my bucket.....Good luck and....

Peace....DHF.........

 

[Weed Killer]

Bush Dr, thanks I’m gonna try with the passive intake for a while but an inlet fan is a possibility.

Bobble, this is too new for me to tell about runaways, I’ve only had the blumats in this setup 3 days, thanks for the tip about the saucers.

My blumat feed is pressurized to 15 psi and I have not had any air/vacuum locks, the first one I built has been running for 3 weeks without a hiccup feeding 7 gallon rootbuilder pots and the saucers never get damp.

DHF, the no brains is because this is the largest grow I have attempted, my usual is 2 plants 2 light scrog, and there is a possibility I am in over my head.

The extract fan is running 24/7 hopefully it’s enough, but an intake fan may be in my future.

 

[bobblehead]

Can you please tell us more about how you've pressurized your feed system and how you went about dialing in the blumats? It looks like a RO pressure booster. Also are you using tropf's or maxis for the 7 gal pots?

 

[Weed Killer]

This is my first setup feeding 5 maxi's

[Weed Killer]

The one on this room is just a bigger version, using a 60psi demand pump and hot water expansion tank regulated down to 15psi.

https://www.icmag.com/ic/showpost.php?p=5236670&postcount=2268

is basically a small version of a well pump and tank.

I will replace the tank with a stainless in the future, the first has a nylon tank so no worries there.

dialing in the blumats i just followed FlowerFarmers directions, soak the pots, dial to cling +1 arrow, but i started with the last on first to purge the main line of air.

No guts no glory....I like your style Bro......

I`m thinkin Bobbles that he`s runnin off a hose bib/water supply with the blumat pressure reducer for the constant 15 psi , but I could be wrong.....

The elevated rez`s above the main rez thingy constantly flooded and overflowed for exactly the same down pressure on the individual cones is basically the same thing , and has been noted at other places to be around 17 psi ftw......but....

Same thing with a different name....anyways.....WK.....Get the saucers under each container to evaluate each container`s runoff if any should appear for insurance purposes as all plants eat and absorb juice at their own rates.....then....

You`re on your way to dialage....so....

Good luck....DHF.........

just checked the blumats and 5 needed to be adjusted up, the pots were getting a little dry. the rest were fine.

 

[Weed Killer]

Been a week since first setting up the blumats, had to re-adjust all of them today, all were too dry, no runaways so far.

FlowerFarmer may be onto something about the coco mix, mine has chips and perlite, and I set up a friend’s blumats in straight coco and he has not had to readjust his in 3 weeks.

 

[Mister_D]

Weed Killer - You are doing an almost mini setup of what i'm building, right down to the chow mix. Definitely subbing in for the show .

 

[Weed Killer]

Mr D welcome

Got the parts for the pump plumbing, girls are looking good, had to turn a few blumats down.

bobble your spot on amigo. This things do make watering easier but no means are blumats the end to watering. Problems arise with these things and if left unattended for extended periods of time, stuff will go wrong. They need constant adjustments.

Try them out for yourself. I left for two days, an air bobbles got in the line somehow and my plants damn near almost died.

Then readjusting them when they dry out like that is very time consuming.

All I am saying is they are not a set it and forget it answer. They do however make your life much easier if you maintain them.
