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

Makes them think they are out in the jungle. The whole room has been coated with 3M reflective glass beads they use in road paint. The clear application insulates and reflects 98% of light. It also makes a great disco with lasers. It costs about 2300$ to paint the room but the hard part was counting the right number of those little glass beads, they are 1/2 the size of a pin head. Well if this was April fools ^^^^^ it would be funny by I'll just stick to the facts. I'm not putting up anything on the walls yet, when I'm happy with the room it will get done as I have 2 rolls of reflective Mylar I got from the National Research Counsel, they use the stuff on the shuttle to reflect 100% of the sun. Nope that's not true is the stuff you get at the hydro store but the good stuff.

LMAO! Damn you had me going... Especially with your location.. you never know.. some NRC mylar. Love it!

Happy New Year (or as we say out East.. Happy New Years!)

God damn. Now you have me thinking about making my DWC buckets into a Undercurrent system. I have 12 13g totes right now. So I have a question. How big of a pump would I need to circulate that bad boy?

And I guess the bigger question.. Did you see a jump in health and yield compared to dwc?

Well you will need a chiller 1/2 hp should do, pump size is based on the chiller so 1/2 hp ecoplus needs a 1000gph pump as long as the head is no more than 4 feet. (that means it pumps up 4 feet high which if you go higher the performance of the pump drops).

I have never see plants grow this well and this big inside. I have been growing for 3+ decades and have only seen plants this big outside. Yes there are 1 or 2 guys who have hit it out of the park but they are very rare. I got 1/2 lb per plant the last 4 grows = 1lb per 1000w. In dirt I need 16 plants to do this, as I am limited to 50 plants, there is no other way to go.

My plants are very robust and love the system, remember I have FU all the grows with the UC and still get an awesome yield. Yes I screwed this one up to but they still look great and I will still get 1 lb per 1000w. I can't wait to get a full grow in with no FU's on my part.

Take a walk over to the THCFarmer and check out the section on the UnderCurrent, it will blow you away what some guys are getting. 3+ lb.

Just as an aside the plants will take a little longer to mature by 7 to 14 days but the yield is well worth the wait.

I crossed a couple plants I had, hashplant, NL#5 and Super skunk and grew them out in dirt to see how good they were. Well they were not that special so decided not to grow them. By some trick of fate I wound up putting 8 in the uc and I got to tell you that's all anyone wants now. So in dirt they suck in the UC they are a star. Kind of makes one wonder.........

Thanks wood for all the info

Any time. The guys over there are great for info but short on humor and no drama over there, real peaceful crowd.

About those uni seals i see alot of sqaure planter bucket! But not much in the way of round planters, is there a issue
With the uni-seals sealing up? I ask cuz im thinking 5gal buckets for a veg uc setup and bigger for bloom. So to the
Point do you think uni will work on standard 5gal bucketss?

People have reported issues using round surfaces, I have both, flat and round and have no issues, if you can afford the ruff totes that go on sale all the time, 10$ that would make it easier. My next one I build will be the ruff totes from Home depot. Most uniseals that leak are because of poor prep when the hole is drilled. Not the proper hole size, not trimming and sanding the finished hole so there are no burrs or bits of plastic. The seals work very well and are more cost effective that bulkheads. I have a 1" uniseal in a 4" pipe and no issues. Use regular blue windex to put together and assembly should be a breeze. I would not go any smaller than 1 1/2 but 2" would be better for small 5 gals, you can get the pipe and most fittings (S 40 PVC) at Lowes. Make sure you get the cleaner and the glue. The pipe has a coating on it from being manufacturing that's a bitch to get off and the glue will not stick! I learned the hard way.

Awsome il will file that info in my uc building plan.

Like woodsman said uniseals work great on well prepared curved surfaces.

When assembling a Uc I put all uniseals, flex hose & air hose line in a bucket of hot tap water. I pull them out when needed apply some foaming dish soap to the uniseal and Pvc than gently slide them together. It's the easiest way I found to assemble.

Thanks for the tips. I have 5 gallon square buckets and 13 gallon totes I could use. I found the roots did better in the square buckets because they are smaller and taller and the bubbles covered more root surface. I have a dehu chiller that would just sit in the Rez. Any suggestions on which size of bucket I should use? I am vegging for about 8 weeks under a scrog (well, I would veg for 4-5 I'm my dwc setup in my veg tent then move them into the flower room an rdwc. When they are done the roots just about fill the 5gallon buckets.

You will need to use the 13gal for flower for sure if veging for 8 weeks. The pump your looking at is the same pumps I am buying for my new system. The mag drives are great and never had one fail.

Great idea for assembly, my first one I used KY Jelly to put together. LOL Now I just use blue windex works great and no mess. I always clean the system so no issues with residue. UC is shipping new systems with a special grease to use.

It must be water soluble grease, that's probably the last thing I would think to use.

Are their words in the two Above posts with the pictures? We need a boner emoticon lol

I tell you, I think there is a link between motivated growers and ADD or excessive compulsion disorder. Been spending hours researching and trying to design the rdwc conversion. The only real bummer is that it seems like a little more of a pia than my interconnected dwc bucket system that uses a ebb and flow bucket controller to maintain water levels. It's kind of pseudo rdwc really as the control bucket drains all the grow sites and then fills them up, thereby keeping the nutrient solution mixed.

Maybe I'll just set it to drain and fill every 30 minutes. It wouldn't be constantly circulating but it would be close.

One question, I read that people drop the water level during flower. Do you employ this tactic? Reason I ask is that if you did you would have to have an adjustable top off float...correct?

Legal got a good question, im wondering the same thing about water levels between bloom and veg!

Also i see you and others run your ppms low theres a reason?
