I dont know if anyone answered this question but Ralfs in PB has dry ice. Go to the fish section and tell them how many pounds you want.

The grow looks superb btw, looking forward to the updates
Thx! I have a Ralphs right up the street from me. I will give them a call.

All the Ralphs around here went belly up, and I think SaveMart took their place.
SaveMart is where i get my dry ice now.

There's a cool idea, there's a lot of socal rep in here and on these boards. I doubt you'll have problems finding participants on any and all levels. Good luck with this, don't let this idea be forgotten.

Thanks MrTokenPuff! I really appreciate the support, it feels good to hear the idea is resonating with some other people too because so far iv gotten a bit of skepticism. I just think it would be really cool to be a part of a underground cannabis cup that showcases the best of what this city has and brings us all together. Anyways, dont want to hijack this thread but id love to have your guys's input over on the CC thread because there are sooo many different ways this could be done and I could use some outside opinions :leaf:

Not sure if I can be of help, I also have a 12 site Undercurrent system doing bluedream under 6 1000 watts with a 1/4 hp chiller. Temps 76 to 79 degrees and water temp is at 70. Undercurrent advised me to go 1/2 strengh on the nutes thru out the whole grow due to the nutes will be overpowering due to the systems recirlating flow and all the oxygen. Mines been running for almost 6 days and tons of new growth blue dream from what I'm told can eat a lot. I grew it before in a farm kit dwc drip system and I pulled 3/4 a Lbow per plant. Just watch the ppms and ph and keep that water temps good and you should pull

Remember 1/2 strengh nutes
Yes, as he said! Less is more in UC! I used to run upwards of 1400PPM on some strains with other hydro setups, but since building my UC setup, I have yet to go over 800PPM(water is ~200 and ~600 nutes max!) I am only on my second round running the UC setup, but things are off the chart so far!

Excuse my lack of knowledge in the subject but what us the difference between normal dwc and ucdwc?
DWC is just using a container with airstones and solution. UC is using containers that are linked together and have a centralized epi-center(control reservoir) linked into the system and has a pump circulating the solution 24/7 in the system. It is much more efficient than just a DWC setup as I stated earlier with running much lower nutrient levels but with accelerated growth compared to just about anything else out there.

Ahh so if you see a resovoir running to six or what ever buckets its a uc system ... Thank you have been wondering that the whole time I have followed this thread

Yes, kind of sort of. All the buckets are connected together to form one big system which has the solution recirculating 24/7. By moving the solution across the root system, it is much more effective then the roots just sitting in a stagnant solution by far. This is why I used to run a bastardized NFT setup prior to this UC one I built.

No worries on hijacking my thread, I think this is a great idea I am down to participate.

Slanty Could you pm me with a parts list for a UC like what is in here and a how 2? I have done drip and nft but not dwc or uc. the results look amazing. I'm a beleiver.

I took advantage of the 30% sale at SD Hydro and got $1800 worth of gear for $1200. I planned on the 2x4 flood and drain table fitting into the 4x4 tent but that did not work out as planned. I have to go exchange it tomorrow for a 5x5 tent. I will post pics after its done.

I did get the bigger hood for the 5x5 undercurrent tent. Here are some pics, that little black thing is an iPhone for size comparison:





Side by side comparison, old and new:




Old and new hood in tent:

Nice bro!

So cams cant tell the story...Do you think the light is better now?

I love the b4 and after, you have almost the exact same angel in both. Great contrast between the 2 hoods!

Thanks man, in all honesty I think the light distribution and penetration is better but its hard to say without a side by side comparison. Either way the old hood is moving upstairs to the new 5x5 tent that I will be setting up today so it's not like I am tossing away good equipment. I am pretty sure that this bigger hood will light the undercurrent 5x5 much better than the old one, it's just monstrous in there. I ended up having to put the inline fan outside the tent.

Good move, and that SD hydro sale was sweet! I just walked in with my gallon jug to get my free worm tea like i do every wed/sat and the place was bumpin! Ended up stocking up on some nutes and trying lots of samples haha.

Are you able to adjust the hight of the light at all?

did u ever consider running a 3x3 flood table in the 4x4 instead of having a big ass tent set up in ur room?
