Undercurrent or rdwc waterfall


gavlp20

Recommended Posts

So I nearly lost my plants these last few weeks with the weather I was using a flood and drain with the res outside the room so water temps was dropping to much. So I have done a undercurrent system before but on a bigger scale worked lovely and I still have the chiller so summer should be no problem so am thinking on a smaller scale like 17lt square buckets with 4inch pipe 4x buckets in the room with the brain and a header tank outside an a ballcock or should I just do a waterfall effect in the buckets

Right so not a lot of input haha 

so I do homebrew and one of the group showed a 15mm silicon hose around the inside of buckets with 3-4mm holes in it looked really impressive so am thinking if I go down that route I wouldn’t need the air pump in each bucket as the surface of the water would be causing enough oxygen for the roots would I get away with that

as long as you have enough water exchange, you wont really need air pump and stones. but it will be better if you do use the airpump to be honest. .

have a look at this link, this lad has grown massive trees in this system, like, truly massive, no air pump.

 

havnt seen him on the forums for years, hope hes ok, he used to be on overgrow, way back when i had hair....shout out to the G-Unit.

Would an aquarium heater in the res not have sold ur problems ? 

I do undercurrent rdwc and use fluming and airstones.

The alien pro uses 4 inch pipe....its just a case of fitting it in and getting buckets that will take them

Nice and thick if ur using 4 inch....put one against the side and have a look....they need to be as low as possible.

@badbillybob has a page with some golden information....I think i posted a video on there were the guy builds his system with 4 inch.

Have you considered insulating the water res?

Doesn't have to be expensive - a sheet of 100mm polystyrene cut for the 6 sides and held together at the corners with lots of gaffer tape. I used a similar thing for a completely different application but same principal and worked a treat.

 

Sorry if this is shite advice :)           :bong:

Old duvet or sleeping bag would be easier...Great idea tho......and my eheim heater can heat 250litres to 20c no problem from 12c

Yeah - my water heater has been working a treat on cold days - if 3 heaters can't get it above 11'C it must be damn cold in there!
