The portability is nice to have, but the greatest benefit I see is the labor ease like you mentioned.

That looks like a great setup. I wanna see the drip rail you come up with. I saw an outdoor one made for less than 100 and grew a dozen plants, but it wasn't vertical, which I think will make a big difference.

I just did a flooring job for a new dispensary/grower and the owners were talking about the jugglr between lighting and cooling that they had to figure out. They were the 11th new dispensary that month in my city alone (OKC) so it sounds like you picked a good industry.
PM me. Those guys are my potential customers and I need to talk to them before they blow a ton of cash on obsolete equipment.

No, each tuffbox is one grow site, and I run as many as a dozen in a given system. The tubs are never totally full, maybe up to 20 gallons each. Because I run waterfalls I can let the sites run almost empty with no ill effects. Add up all that capacity and you can see why I don't need a separate reservoir.

I get 27-32oz per plant.

Yes, waterfalls alone provide all the oxygenation and mixing I need. I don't even need to run a water chiller, anything from mid 60s to mid 70s is fine.

I grow each plant up a vertical trellis, 6' tall x 4' wide and SCRoG. I run 900W of COB LED using water cooled fixtures of my own design per trellis.

sorry for butting in but 27 to 32 oz per plant? is that dry? im only doing 15oz per plant but in a 2m tall tent.. is the large amount due to the extra space growing vertically? i run a 4 x sites 64ltr containers waterfalling to each container with about 7000ltr an hour pump and chilled..

maybe better training eh?

what plants your running for that kinda weight?

are they all led cobs?

sorry for all the q's

Yes that's dry. They were individual plants on a trellis panel that size. Yes they were trained. Yes I used 900W of COB LED per trellis.

Hi loving what you do just wish i had the vertical room to try it.. Can i just ask what cobs you would recommend if i was to build my own lighting? i'm a design engineer working in electronic packaging so right up my street.. how many for a 1.2m area would you recommend i am thinking 6 to 8?( would like to match 1000w hps if possible) i run in a tent 2.4m x 1.2m x 2m but got another 1.2m x 1.2m x 2m i want to run with cobs. what it the best colour 3000k or 3500k? what do you use?

any info would be massive thanks again.

You can run vertically in a 6' tent.

That plant was grown with Cree CXB-3590 CD bin 3500K chips running at 54W each. 16 chips (4 modules of 4 chips each) covered the 24ft² trellis.

The plant might have gotten more light than it could use, due to my running cold 60F water through the water cooled modules and this achieving better than the rated 56% efficiency at that wattage. The ratings come from running the chips at 25C/77F. Cooler makes them run more efficiently.

Cooler was not good for transpiration, however lol

Those modules are several years out of date so don't emulate them lol

Talk to HLG about their boards. They'll be able to set you up with a kit that will absolutely kill a 1kW HPS over that area.

Thanks for all the info.. I may setup vertical on my next tent then.. seen some today 2.2m tall so a bit better that my current system.. what size totes do you use per plant and how wide do you train each plant.. I'm waterfalling to each location with my current setup as you are and no bubbles..

Will take a look at hlg but would of liked the project tbh ha. Anyway no doubt I'll be back on with more questions.. always learning eh.. would you mind the PM or just find you in a thread?.

I used 27 gallon tuffboxes as tubsites because I was growing 6' tall plants. Honestly, the approach was a workaround for low plant count limits and isn't the optimal solution for getting the most from the space; covering the trellis with more, smaller plants works better for consistent yields, among other factors.

The reason I suggest a kit is because the guys have already don't the work of matching components to ensure good results. If you don't want to go with HLG there are others, such as @CobKits. Lots of great people to work with here!
 
How To: RCDWC/UCDWC



due to popular demand here we go, ill put up the pics then a explanation, if that doesnt help you then ask away!!30L autopots
210mm net pots fit perfect! mark and cut!




2.5" hole saw for 1.5" (40mm) uniseals that i used, u can use tank fittings instead.



this is how the 19mm fittings will go , the pump in my 60L remote external res! hailea 3000lph!



res with uni seals in ready to go!



i used 1.5" waste pipe and pushfit elbow to join all the return lines together, the returns are so big as i recirculate at high speed as im not using airstones!



now for the feed line/waterfall effect style feeds! 19mm irrigation tubing



heres the self cutting clamp the inline pump and ud return it to a t piece in the res, its a mock up so just imagine all the lines are there lol.......





self cutting outlet clamp....used for washing machine waste, got it in B and Q they should do them any plumbers or hardware store, dont know if this sites us or uk as im new here, just came to se hiesenbergs tea bit and seen a huge DWC following so thought why not stay around, so heres my bit for the comunity done!!!

Noo i cant see the oics
