drawing board dude
4 32 site xl undercurrent systems in a 20X40 room
- Thread starter bdt1981
- Start date
Rdwc is very technical systems, anyone I’ve ever seen build there own are always tinkering and trying to change things between runs. The CC systems take out all the guess work and they also use better containers and bigger pipe than most home made systems.
I still have the believe that rock wool drain to waste is cheaper. But we already discussed why your doing rdwc and I get it. Not what I would choose but I get it. Drain to waste sounds like it requires more water but you really don’t need much run off at all. Jungles boys claim they don’t even get run off on most the waterings. So pretty much all the water gets used where as in a recirculating system you have to dump water and nutes down the drain after a week or two. I didn’t understand it either as I figured ebb and flow would use less water since it recirculates but plants are gonna drink about the same amount anyways and instead of just small amounts of run off you have to dump the whole Rez.

That would be a very bad move to diy a 32 site uc system. No possible way would a diy be 1/3 as good as buying one. Not to mention the giant pain in the ass it would be even trying to build one let alone 3. No way no how. Some diy guys like to say they can build one that works as good as current cultures but they are sadly mistaken. The plastic the buckets and lids are made out of will be nearly impossible to duplicate with just buckets off a shelf. They will for sure leak light and probably water at first. I think i was quoted 3800 each on my equipment list from growgeneration. What kind of amature would i look like in a legal medical grow with some diy bs? No thank you there. The only diy im doing is stands for the 146# ceiling mounted air handler to mount to since my ceiling is 14ft high. I have an idea for the right height stand out of 2x6s that will be better for me.

ime.i would give a 4-6 maybe even up to 16 site a try if i was growing at home but not in a legal commercial grow.
Air handler? I thought you went with the mini splits?
What about labor? My time isn't free you could still build it cheaper than buying but it's probably a couple thousand in labor for each system

its gravity controlled, it has no engineering to it. I can build a 32 site with EVEN FLOW in a day. period. uni seals are fool proof as long as you sand, I understand not wanting to do the work. but 2600 dollars for a days worth of work is horseshit. what are you doing? cast molding pvc pipes yourself? how is a pvc pipe cut to even proportions rocket science? its easy to keep a symmetrical feed thats even on the ground. my 5 gallon black buckets look just the same as your rounded rectangular buckets except I get to go to fucking mexico with the extra money I saved. lol. pay what you want but that shits easy work.

I can beat it with non bulk internet pricing.
100 bucks for 32 black 5 gallon buckets
174.72 for 64 -2 inch uni seals
60 bucks for 36- 6 inch net pots
$161.50 EcoPlus Commercial Air 7 - 200 Watt Single Outlet 3566 GPH
30 dollars for 32 airstones on ebay (40mm disks)
25 dollars for 30 feet of 2 inch pvc.
whatever water pump is less than 100 bucks
I'll even give you the benefit of the doubt and round up to a grand for cost and itll still beat that 3 grand estimate by 2k.
catch my drift?

lets just break it down this way. each plant you grow in dwc is going to take up a 3x3 square space 6 of those on the 20 ft wall, and 12 down the 40 foot wall. you only got density for 2 systems IF you dont have room for anything else in there like walking. so how "professional" do you want to look?

I take it you will be growing one strain at a time from seed with no mom area?

That is the response all the other diy guys would say. Lol. Wtf is gravity fed in the uc? Its actually powered with a inline danner mag pump.
Mexico with the extra money huh? Well my funds arent hurting like that. I have no problem spending 35k on equipment for a professional grow room that is going to get minimum 2#s per light up to possibly 6#s. See thats 48 on low end times lets lowball at 2k each wow 96grand every 11 weeks and only 35k initially on equipment. But to think i could have spent 31400 and saved 3400 bucks if i wanted to build it myself. But then i would look like a fool that the state would prob shut down because the plastic home depot bucket dosent have a food safe stamp on it. Lol. Naaaa as difficult a decision it is ill just spend the extra 3400 and be professional about it. Plus cch2o customer support comes with the new systems.

Your drift is non existant. Your talking 9grand at your numbers on something that is going to pull 400grand in a yr. Im taking this grow serious. Your 5 gal buckets will allow about 1.5 weeks veg tops. Gl with the seal on the round bucket as well as the perfectly alligned holes you will be punching. All 96 of them. Its retarded to even consider building it. Oops forgot this is coming from the guy who thought the wort chiller was in a freezer box. That makes you now invalidated as a grower. Well imho anyway.

I have mom area and plenty of other small rooms just nothing big enough for commercial grow. Here is a drawing to scale i had to draw up in order to apply for building permit.

Cch2o says 12x20 for the 32 site xl system. That is plenty walking space. The system measures 9'4"x18'5". Im starting to believe you're trying to sound so retarded for the fun of it.

if you gotta ask all the questions I’d step back from the dwc and try drain to waste or flood n drain as you don’t have an understanding of what you need to do and that’s too large of a scale to learn. Dwc is unforgiving for new growers.
6000btu per 1000 watts of light is the rule of thumb for sizing ac. Looking into central ac for rooms that large as mini splits don’t move enough air.
