The second round with the UnderCurrent, The $6,500 expearment gets better

[UnderCurrentDWC]

Do not clean Stainless Steel with Ammonia or cleaners like that as they will pit the SS. Use CLR or something like that.

That's a good tip! Thx.

Your chiller idea sounds like a good way to condense the power used for cilling h2o. The only thing I might suggest is wrapping that rez with a hot water heater blanket for insulation.

Good shit woods!

Uc~

 

[woodsmaneh!]

I may put a fan in front to help cool the room, if not than that's what I will do.

 

[woodsmaneh!]

I jacked up the ppm to about 900 and they did not like it at all so back down now. New cages, found this fence it's 16 g and vinal coted, squares are 2 x 3 and it is easy to work with, comes 4 feet tall.

Ph 5.6
ppm 780
res temp 61
room d/n 83/70
Humidity 35%

Going to add the second humidifier tonight so will show some of the work later. Hose fell out of one of my 45 gal RO collector and drained on the floor, no harm due to the EDPM liner. Will add some humidity also.

Very Cool!, You might consider using ice chest for your res. I use 2 120 quart Igloos, one for my res and one for my chiller res. Makes for pennies on the dollar to cool. I even use the 10 gallon Igloo round coolers for my flower pots,huge roots!

People just continue to amaze me with what they think up and use. Dam stoners are the McGivers of the world. Well done 907 and you have given me some ideas. Thanks for stopping in.

 

[legallyflying]

That's the gene I use for my scrog. The dehu chiller doesn't really save energy..I mean, it won't dehu the air anymore. But it does work waaaaaay better than a standard chiller. Freakishly better.

Looking good

Just discovered that my one res is 50 and the other is 52, WTF so they were running hot I stuck a 6" duct in there from outside, last night it was -20, room was at 60 so plugged up the 6" that will bring the temps back to 62 in the res and will change out the 8" for the cool tubes to 6" and slow the fan down and install a damper that will bring the night time temp back up to 70. It all looked fine last night glad I checked this morning but I slept in a bit. Any way hope the ladies are OK.

 

[907]

Right on Woodsmaneh, I have been watching yours from afar.
Yo Legally, we were talking last year about the ecotemp on demand water heaters for CO2 gens. Anyhow happy holidays from my crazy girls to yours,MERRY XMAS PEACE 907

 

[woodsmaneh!]

Boy what a screwed up 2 weeks, first room was getting into the 95+ range, so added a 6" cooling line to the chillers, well got colder than I thought, checked the room 12 hr later and both res were at 50 degrees. holy shit bat man. Found the issue and fixed it, back draft damper, big $$$$. Took 6 hours to get temps back to 62. One plant looks like it thought it was time to go...

O did I mention the filler hose fell out of the RO tank and drained on the floor!!!!! my mistake took the clamp of for something else.

O ya it gets better, look in 4 days ago and I got Fucking Spider Mites the 2 spotted types. I used Avid on them and than nuked them again tonight and will do it again in 5 to 7 days. Get them all, little bastards, think I got them from bring in wood to burn, note to self change clothes or garden first. So other than that it's all good. Will get some pics in a few days.

Did I mention the computer died and had to get a new one.....another time


I am using Avid on them started Tuesday and sprayed again today. Due to the life cycle you need to spray at least 3 times to get them all. I do it every 5 to 7 days and than check under the microscope. Little bastards...


will keep you posted.


By the way Avid can be used up to a week before harvest and is safe for human consumption. It is toxic and can make you sick if it gets on you or you breath it in. Turn all fans off when using. I wear a Tyvek suit, respirator, hat, goggles and gloves when I use it. You can down load the WHIMS info on line here

Protect yourself when using any thing like this. And keep out of reach from anyone.

 

[woodsmaneh!]

Well here are some pix of the progress been a tough 2 weeks. Happy New year all..


The one Koush is doing well tons of flowers, my one plant on the end in the corner thinks it's time to die but is coming back. Did not like the 50 degree res temp from last week. 3, 6, and 8 are the Pix of the KO F2 from sannies. The others are my cross.

 

[sweetswisher]

very nice plants man

 

[hellraizer30]

K wood i understand the basic concept of uc but im a bit lost on how to add a res to it?

Without a res your adding back water thats in direct contact with the plant!

My idea wouldbe to put a pump on a switch to pull out all the water in the system that
It can get out, to the res then add back ph the send it back to the system?

How do you do it?

I have a central res that feeds all the pails. They are all connected with 4" or 3 1/2" pipe. The central res is fed by a 45 gal raised back up res with an auto fill on the plant res. side. I use RO water and don't even ph as it is at 7.0 but because the ppm is so low as soon as it hits the plant res it corrects to 5.5 to 5.8 so no issues there.

Here are some pix showing what I did and how it works, any more questions ask away bro..

So wood you recamend building a systen or buying one, im looking a just 5 to 8 gal planters, with same for control planter

i was thinking the same but for the price do you really think that its worth the money? i mean i'll be tossing close to a grand in supplies plus buying this new one for in the range of 2g more do you really get 30-40% better yeilds?

 

[hellraizer30]

The yields with uc are the best! Crazy yields

 

[LT1RX7 Drifter]

i hope you plan on putting a reflective film up your losing a ton of usable light on the wood walls, i suggest some stuff called reflectix frome lowes or home depot its cheaper and 1000% more durable, its bubble wrap with mylar on both sides, has a texture so no hot spots, you can get a 4ftx 50ft roll for $40ish, I can say i am very pleased to see this thread and read about your grow your doing sweet keep it up, why so many res containers are you gone for long period of time or something it seems like a lot more work mixin nutes

If you look on the secound to last pic you will see hes takin care of that

As I am a med user I am limited to the # of plants I can grow. In all my years of growing (since christ was a cowboy) I have never ever seen plants grow so well and SO FUCKING BIG INDOORS.

I have screwed up all my grows and still pull down 1/2 # per plant = 2 plants under a 1000w = 1#, these systems can grow 2 to 3# under a 1000w, I just need to stop making mistakes. Takes a whil to diial a big room in when you have temps swings out side from 10 to -25 in the matter of days.

Growing organic it would take me 8 to 10 plants to produce 1/2#

These plants will drink 5 to 30 gal a day so need lots of water, the systems have their own res and than I connect to another res with just RO to auto fill the system res's. I have mylar to9 put up but still setting it up and I think I will go back to hoods vs cool tubes as the tubes are not as effective at directing light.

The yields with uc are the best! Crazy yields

Yup and will turn OK weed into very good weed. I was going to toss a strain but one got into the UC and boy am I glad it did it's a keeper, I grew 9 out in dirt and they were so so.

First issue is cooling the water if you can't do that than I don't recommend one of these. So if you got a way to cool I would build a system you can save 30 to 40% using cheaper equipment. Uniseals can be bought online anywhere, I would go with 3" if you are using 13 gal pails and I would use the rough totes that go on sale all the time, min 13 gallons to max 20 gal. My buddy builds these for a hydro shop near him and he has a thread on here

https://www.rollitup.org/dwc-bubbleponics/478010-flowering-undercurrentdwc.html

I also show how to build my big blue system at the start, click on the sig at bottom.

Over at the THC farmer they have a whole section on the UnderCurrent have a look, lots of stuff there but not a DIY thread as it is sponsored by UC, I'm over there under the same name buy no ! at the end.


Thanks for dropping in, hope I answered your questions if you got more keep them coming
Peace and Happy New Year.
