Lazyman's 16KW Headbanger

[Lazyman]

OK folks, picture time, these are from a week ago, so things are bigger now, will take more pix this weekend.

Grape stomper at 6 weeks flower, getting fat!

Veg room, this was my first and only attempt to try and transplant the vveg room 2 weeks before the flip, what a crowd!

Now I will only transplant at the flip, no room for the 5g smartpots in veg:

Here's a sneak peek at what the room looks like now, added 5 more ROWS of big bushy purple AK's I got from a buddy, now I can hardly walk in there!

Lazy,

Thanks for the cudos.. It really stems from my desire to be the best in the world at whatever i do, i just don't know how to settle for mediocre Of course, we are all still learning every day but i don't stop with sufficient (i'm a scientist by training) i like to know exactly why and how something works and i need to understand all of the mechanisms involved. A simple correlation just doesn't cut it when you're shooting for perfection.

That being said, i got another question for ya - i'm using the Sentinel CCH1 controller (which you recommended me in the past - thx buddy!) to monitor my room and i noticed that my humidity at night is often around 75%. I assume this is a normal part of plant transpiration, but should i be using a dehumidifier during the night cycle to soak up all that excess moisture, or does it have a beneficial effect on the plants? Does night-time moisture assist any biological processes that you know of..?

Thx again..

p.s. chek out my journal, i left a lengthy response to your last post

 

[Lazyman]

Hey Skiz, yep I'm the same way, don't tell me that it works, tell me WHY it works!

So the simple answer to your question about RH, yeah that's typical, and yes use a dehuey to counter it. At your size you're on the edge of needing a Santa Fe classic, but you could probably get away with a 40-pint unit per room. How do you control two rooms with one Sentinel? i know you were having trouble with controlling the AC's, I would probably just use a regular digital programmable T-stat for each AC, and use the cooling outlet on the Sentinel for an emergency exhaust fan in case an AC fails. Or, buy a second Sentinel! (ouch)

Lazy,

I'm kinda toggling between rooms based on which i need to keep a closer eye on. Since my rooms are side by side, i'm able to move the little sensor to either room manually. And since i've cut out my co2, i've really no serious need for the thing other than to tell me my daily stats. Both rooms are controlled by their own a/c, and i also toggle my dehuey and hueys between rooms as needed. I know, i'm a little under-equipped for this scale, but i'm on a serious budget, build-out and start-up is always more than you anticipate..

Could you explain how a digital programmable T-stat works? If it's what im thinking, it won't work because when i kill power at the box one of my a/c's doesn't automatically come back on and i have to actually go in there and push the button (samsung digital..). Also, i wasn't sure how much load i could pull thru the Sentinel, and furthermore i prefer to run them on the 220 rather than the Sentinel's 110. Let me know if there's an easy way around this.

Could you also explain to my why i should be sucking out all the moisture during the night cycles? How exactly does this assist the plants in their development? My guess would be that it simply allows the plants to pull more moisture (and nutrients) through their vascular systems in total, but it's just a guess...

Wowzers! This is some heavy shit lazy.

You just sold me on these Blumats. Im working my way through this massively entertainling thread. Ive got 15 pages left to go and you haven’t even got that Co2 rockin yet plus did I hear you mentionthe possibility of 24KW!!! This is getting scary. I cant wait to find out if your ever pourd that concrete.

Mabye I haven’t got to it yet but Im wondering where you pull your intake air from and where do your exaust. Strait from outside back to outside?

 

[AOD2012]

wow, things are looking great lazy, i hope and also exect that this time around you will get as much out of it as you are expecting. keep up this craziness and thanks for giving little guys like me something to look up to.

Powdery Mildew.
You put yourself at great risk of getting it with humidity above 60 and it is a real bitch to get rid of.

Hey buddy, yeah builds are always expensive, I try to lean towards $2K per light on a raw setup (plumbing, insulation, wiring needed, etc.)

Let's see, you're using wallbanger ACs? Yeah if that's the case you can't do much for them, if you were electrically handy you could bypass the internal thermostat and controls, and hard wire in a programmable house thermostat to run it instead, but it takes some knowledge. A 240v relay with a 120v trigger might help in another build, but it still requires AC's that can recover after a power failure.

As mentioned below, the powdery mildew is the biggest risk of high night RH. Nasty stuff that's very contagious.

Hey buddy, thanks for stopping in.

No Co2 yet, AC's have to go in first, but the 3X electrical sockets are being finished as I type. AC's go in next month, then CO2, then 4 more KW in flower, and 2 more kw in veg. So the final numbers will be:

20KW flower
4KW veg
1.5KW mother room

No concrete pouring, it was deemed to be an unworthy pursuit.

The intake pulls from a dead space behind the false wall that divides the room from the dirt floor section, exhaust go out a window I removed and put up a sheet of plywood over, with 4X12" collars for exhaust ducting. 4400 CFM out one window!

Thanks man, I'm guessing 5-7# for the next crop in a week (4 rows of plants) then the following crop should be about double that (9 rows of plants.) Gonna be an interesting summer for sure!

Lazy,

Hey man, got an issue goin on wondering if you could help.

What is this/ Mg def?

 

[Lazyman]

No I usually see mg def as brown spots on leaves, this looks more like a p/k overfert but to be honest I usually have to go look up pics myself. There's a pretty good "Sick plants" sticky in the infirmary, I use it for comparisons

 

[SkizOflan]

p.s. i just got fungus gnats! Any suggestions? I plan to not feed water for two days, then hit em with a 1:4 h202 mix. I also plan to put those yellow sticky papers all over the place, i hear they love the color yellow. Oh yea, i added a few 10" vortex's to get some additional air flow under the canopy. Have you heard of fungus gnats doing any harm, or are they just a nuisance.. i see 4-5 buzzing around the top layer of coco on almost all my plants in both rooms!

I've dealt with the mites before, but never gnats. This is just weird..

Thx buddy!

 

[Lazyman]

they are mostly just a nuisance but gnatrol works best, and yep yellow sticky traps! Watering less helps too.

Don't give up too quickly on the Purple Mr. Nice. I just got the cut from a buddy who pulls just shy of 1 lb from each 600W light.

Very nice grow, Lazy. Fun read!

Yes builds are always more expensive than you think. But after the first harvest you should be able to reinvest and get everything proper.


I am going to touch on a couple things you mentioned having no idea of your size.

The CHHC-1 is great but you are not really using it now the way it should be. Not sure why you cut CO2 out.

Humidity. IMO you want this in check all the time. I would not want my buds sitting at 75% RH at night. I always used a separate DH, I could not count on the AC as the only DH.

DH. Santa Fe's work great. You need to Google and see how DH's are rated, it is interesting. Also look at power consumption. The Santa Fe's use no more, or just a tad more than than a retail unit and pull out A LOT more humidity. But they do cost money. Buy off Ebay and use Bing for cashback.

wall bangers. LG units have an auto restart feature that allows them to power up after power is shut off.


CHHC-1. This thing really can not directly control all the equipment it is programmed to control. I used relays to control my AC, DH, etc.


So basically you can use the CHHC-1 to control the AC, you just need a $20 relay, and an AC that will restart. Maybe you can mod the AC

The programmable/external thermostats cut the power in & out within a given range.
Your AC's should ALWAYS come back on (auto restart) where they left when the power to them was cut for whatever reason.
Just one simple flickering in your electricity supply line will cause the AC's you have shut off until you turn them back on - if your lights are running while the AC is cut off there is a high potential of cooking your plants!
All THESE have what you want/need and they are cheap.

The Sentinels handle 15AMPs per internal relays (some models have two of them - one for night/day, the other for either of the two).
Sentinel also offers external relays (see pic below) controlled by a trigger cable coming from the timer.
Those handle 4kw each, 120V or 240V, and are stupid simple to wire up.
