20,000 Watt Medical Grow Op Construction

[TheLastWood]

I can't wait for the induction test I've been excited about it since you first got the light. We have such deathly hot summers here if they can produce like an hid with the heat of a flourescant ill blow my top and go buy a few!

 

[TheLastWood]

With a cooler lighting system I could go full steam all year. I have such a good lineup.

Growing plushberry know and have 2 cataract kush seedlings (og kush x la confidential)

In seeds I have la cheese, sage, blue widow, critical + and I finally just ordered romulan and grapegod. I'm turning into a strain whore. Ill only grow 2 at once but if I had gardeners setup id be growin like 5 lol

I just stopped lurking and I've been reading this thread for a few weeks and thought I would drop in to say how much I appreciate all you're doing. This is a great thread and what you're doing with your grow is fantastic. The fact that you are putting effort into finding people truly in need to donate to just great.
I have GI problems that cause frequent nausea and vomitting (I went from being 5'7" 145lbs to 107lbs in less than 6 months, a year later and I'm up to 117lbs) and I have an autoimmune disorder that isn't doing well that my doctor and I are giving serious thought to putting me on methotrexate (a chemotherapy drug, albeit at a fairly low dose) for. I'm in NJ and they're doing everything to stop MMJ from happening and it's just wrong. I'm technically anorexic still and the pills just don't cut it. The best antiemetic out isn't even enough to stop the vomitting when it's bad, and eating when you're nauseous is really hard. Smoking doesn't just help more with the vomiting, it let's me eat. I really believe if it wasn't for smoking that this would have killed me by now. So I can pay tons of money and risk my freedom or waste away to nothing. It makes me really happy to know that there are people out there trying to help people like me.
Sorry for the rant, the way MMJ is getting blocked out here upsets me so much it just spews out sometimes. Thank you again for your hard work to help people and for showing us how you're doing it.

The induction light test is days away. The clones are rooting right now. I'm only going to veg them a week or so. The test will be bloom only. We have the lights and table set up and ready to go. Thanks for the patience. The mites at the same time of trimming took up alot of time. Sorry to all. We will get this test started in less than 10 days.

I like the ribbon jet, nice one! I'm gonna make one of those!

Just a 2" main drainline? You are serious about low flow. I hear you about the chillers. My workaround would be to leverage the cooling capacity of the chiller. To do this, I'd have the chiller cool a manifold. The manifold would be an independent circuit with pump that has a heat exchanger in each rez. That and having the buckets insulated and resting on concrete would have you get as much cooling capacity from a single chiller as you can.

With the inductive lights test, I'm an 'and/also' kind of guy. Do you have space limits from testing both?

2" will be PLENTY big enough to drain 8 buckets...even with good flow. I'm only feeding with a 1" line. I, too, though about a heat exchanger. My marine mechanic bachground took me right there. LOL. I'm thinking copper coils in each res off of the chilling manifold. I also want to place some sort of putty under the buckets to make fulll un-insulated contact with the concrete floor. A little circle dam filled with water would be ideal, but not feasable. I just want that concrete to eat as much heat from the bucket as possible. You see what I'm trying to do?

Fuck man...I wish you were here. I'm so sorry you can't get the meds you need. This pisses me off big time. Fuck this...stand by for a PM.

If you think the 2" will work, I'm sure it will.

My math on it is something like this:
Drain sizes are calculated by a fixture unit which is generally 7-1/2 gpm.
Your pump is 1000 gph or ~16 gpm.
There are eight buckets so the flow will be 2 gpm per bucket.
An individual bucket with drain at 1-1/2" rated to 2 fixture units allows for 15 gpm before overload.
A 2" pipe is rated 3 fixture units which drains at 22-1/2 gpm.
With only 16 gpm input, I see how you would think this is plenty.

Still though with 20' of horizontal run, I'd put a vent at the head of the drain line.

As for the putty, what about some thin-set mortar? You've got your no fuss low-tech thermal transfer putty right there, inexpensive to boot! Come to think of it, you could design it to be damp with a dripper during lights on for evaporative cooling to add to the mix too. (Ok, now I get your reference to the circle dam.)

the ignition test, what a moment. I pop in every now and agian keep on rockin, mites during trimming ouch. Good luck keep on rockin.

I do my math a bit different.

I have a couple old aluminum fuel tanks I removed from a boat in my shop. They both have 1 1/2" fills. I connected the tanks fill nipples together with 1 1/2" hose. I then put a garden hose in one tank full blast from the household pressure in the shop. Since the tanks were cut in half to remove them, I could see the water go from the first tank to the second through the 1 1/2" hose. At full blast the water level in the 1st tank was only about an inch higher than the second the whole time. Even IF I was using the same volume of water (which I'm not), the volume will be flowing through 8 pipes, not just 1. A small water level difference is fine. In fact, it could vary several inches with no effect on the system. I'm thinking of supplying the buckets with solution via a ribbon flow AND a couple spray fittings. A 30 micron filter should keep clogs to a minimum. The return water to res will be under water. To maintain O2 saturation in the res, I'm thinking a second small pump with elevated sprayers blasting the surface with a dozen streams of water.

I like the thinset idea. I'll just dilute the shit out of it with silica sand to prevent a strong bond with the slab (I do need to move out one day).

The T-5 1 system (basically a cloner, but just with an air stone), and the T-5 2 system ( air stoned buckets to a central res) are complete and growing plants. The T-5 2 plants are now touching leaves (after just 6 days!) and need to be moved into the new designed bucket system under 2 1000 watt MH's. This MUST be built tomorrow. Then I just need to keep building one 8 bucket system at a time to keep recieving plants as older plants are harvested from bloom. In about 10 weeks, the whole op will be 100% DWC. I've started the flush on our first 2 DWC plants today...known as Godzilla and his buddy. From previous experience, this flush will take less than a week, as opposed to 2.5 weeks with the coco. I'm really looking forward to the final yield results of these 2 plants, as they are the exact sized plants I can grow to fill out the room and stay under our plants limit. Up until now, we've been kind of "freestyle" with any total yield calculations. Now, we can start fine tuning and pumping up the yield over this summer. Once the DWC is perfect, it will be time to seal the rooms, add the ductless A/C system, and fire up the CO2. Play time is over. It's time to get serious. Helper D's job is about to kick into overdrive.

I checked out your grow. Very nice. I'm a fan of those vertical light systems. Have you checked out Kitty's vertical bare bulb settup? The Canadian Kitty that hangs here...not the basement grow Kitty.

Thanks for the well wishes. It's weird, I know I have serious health problems but knowing how much worse they could be makes it seem not so bad. I could have cancer or AIDS and have all the wasting problems and have something else killing me on top of it.
It offends me so much what is happening here about MMJ, the population is strongly in favor of it, the legislature voted for it, and the asshole governor thinks we're all wrong and is doing everything to prevent the law from going into effect and weaken it should it ever come to pass. I fail to understand how alleiviating suffering can be a bad thing.
CG you did inspire me to do something with the new grow. I have a friend who has the same kinda stomach problems who won't be paying for weed anymore in the near future.

For whatever reason (and theories abound), there is strong resistance to marijuana in all forms: medical, hemp, recreational. There must be a ton of money behind this resistance to basically over rule the will of the people in so many cases. All we can do is keep on yelling until they hear us. There has been some great lawsuit victories in my county with folks getting paid well for having their meds destroyed by the cops. The best one (I've told this story before), is when several years ago a cop testified to the "street value" of some marijuana to make a dealer look big time. He came up with like $6,400/lb. Last year that testimany was used to place a value on several pounds of meds unlawfully destroyed by the police. The police department had to pay the couple the amount that their own officer inflated. Since then, the police department here no longer gives ANY testimony regarding the price of marijuana. Furthermore, they will not offer any "expert testimony" on marijuana growing because it keeps coming back to bite them.

Dude cops don't know shit about shit.

I think its fucking hilarious how little they know about drugs. Think about it, if you were taught nothing but bullshit propaganda and told to enforce it on ppl, you would stupid too.

I've had cops tell me my mexican brick weed was "very potent" because ithe liquid turned purple when he droped it in a vial. Lmao

But if I go on about all the stupid shit they do this will be a very long msg.

The tides are turning, ppls eyes are opening. With every piece of information known to man is at the click of a button, they can't keep the truth covered up as well.

CG, how's the good fight going!? I see you're going 100% DWC now, I remember reading on another thread you checking into bare bulb growing, are you still planning on leaving any room to experiment with that? Or is being 100% DWC going to suffice for growing the size of plants/trees you were hoping for while staying within your plant limits?

Hope everything is goin good with the grow....Was just checkn back in to see if the predetors did any justice or if the mites are back in full effect?I also had a question i been asking around about and wanted to hear your expertise on this subject..I have a completely sealed room other then exhausting the lights..I have a watercooled c02 gen running at about 1500 ppm with lights on...In the dark period i have been seeing high ppm readings all the way up to 1700 ppm..I have never seen levels this high at night..My room must be very well sealed to be building up these levels from the plants producing co2 at night...Anyway hears the question.....How detrimental do you think these high nightime levels are?Are they not getting enough oxygen at night with these high levels?I was thinking about exhausting at night but never had to before in a sealed room,,It kind of defeats the sealed room purpose..I also tried cutting off the gen an hour before lights out but the levels are still high in the middle of the night...Also this is a hydro grow and plants seem to b looking fine.........Anyone feel free to chime in on this if you have any input on this matter....

I don't know if the pot issue is enough to trigger a revolution, but if you add that to the other 11 inches of dick they're jamming up our asses, it may just be enough. I don't know about you, but 12 inches of politician's dick rammed into my life's ass is the absolute limit. Sure, they use lube...good lube. That's why we don't feel the first 10. But, they're starting to get greedy with the dick giving. They'll be lucky if we all just say "take it out", and not "take it out...now bend over...it's your turn".

We still want to do the bare bulb thing. Before we try it, we'll need to get our plant size dialed in for light spacing. So, we'll get the size dialed in with the DWC, and then try a row of bare bulbs. We also may try some vertical induction lighting since we can get the plants so much closer to the lights. Thats the down side with bare bulb vertical...space. It takes alot of room because of the spacing needed between the lights and the plants. Induction lighting could increase the amount of plant area/light. For now, we'll get the whole room DWC, test the induction lights, probably buy a couple 400 watt induction lights for an overhead test, then start with the bare bulb stuff. As you can see, these rooms are not for short term use. I had my shit perfect prior to these pesky plant limits. I used to just throw down 500 plants in a SOG, and grow. Now, I've had to learn canopy shape all over. I imagine there will be a big shift towards large plant growing as folks search for more yield per plant.

I the predators helped, I couldn't tell. We're back to spraying. I've found that the Ortho Petrolium Oil works the best. It actually kills the eggs. We alternate that with Aza-Max, and a Pyrethium bomb in the Veg room every 2 weeks. We stop all spraying 3 weeks into bloom. We're hoping that the new plants will have enough oil on/in them to deter the mites in the last 5-7 weeks (the Laughganis take 10 weeks).

I have had the exact night time CO2 problem. I chose to vent at the start of lights out. But, I'm not sure if it was a problem. I would worry more about any time you have elevated CO2 levels during lights on...even an hour. The plants get addicted to the highest level they experience. If you ran 1500 ppm, and then went to 1000, your plants would grow slower than if they never had CO2 at all. I learned that first hand. So, the 1700 ppm time could be getting your plants "used to" that level, and then not maximizing growth during the 1500 ppm times.

My commercial growing buddy did a great test to prove this. He had a 2 room flip for blooming. One room he ran at exactly 750ppm during daylight. The other he ran up to 1500ppm, let it drop to 1000ppm, before running back up to 1500ppm. The 700ppm room grew MUCH faster and bigger. Since then, I've always just used 1000ppm, but used equipment that would keep every part of the room exactly at that level. I had 4 meters in the room, and kept adding fans and changing fan locations until I get every meter reading the same. I don't feel that one meter is enough. At least not enough until you get your air movement dialed in. Fortunately, I have access to several meters from a friend. Given their price, it could get expensive. When we seal the room in June, and add CO2, we'll use several meters to achieve consistant levels.

Anyways, I think it's up to you. I'd see how much extra gas you're using if you vent the room at night. Or, if everything is rocking perfect, why change?

Which water cooled gen are you using? Are you using a water chiller? How big is the gen? How big is your room? How much gas do you use? Cost? I'm in the market and like the water cooled units. My buddy says they suck, but he hates anything newer than 10 years. Sorry I couldn't give you a better answer. Maybe someone here knows if the high night levels are bad. I know that I'm going to use my CO2 to BLAST the mites with some insane ppm level. I want to find out what levels will kill a mite and what level damages a plant. I hear that it's the best way to kill every single live adult mite in the room.

 

[hellraizer30]

You look into that mighty wash for bugs?

 

[mr.smileyface]

Azamax is the best IMO I spray twice in a cycle and never get any bugs. People think its just a neem concentrate. But its an antifeedent. Works killer in my show and i swear by it. I mix about 7-10ml per litre and spray right 15 minutes before the lights go out. I try to only spray the underside of the leafs where all those little shits think they are gonna live. Really easy to mix aswell. Im not advertising it, just passing good info along. The good growers already know about it.
