greenkush Posted August 29, 2021 Share Posted August 29, 2021 Been wanting to go rdwc for ages, never did but decided I was over coco and all the mess involved. So built my own due to the ridiculous cost of off the shelf systems. a few minor mods left to do tomorrow and I’ll be doing water tests. 9 1 Quote Link to comment Share on other sites More sharing options...
Batista Posted August 29, 2021 Share Posted August 29, 2021 I'm in the same boat as you, tired of all the mess with drain to waste coco. I'm going to do 2 stacked 110l tote,(bottom section to catch and send water outside) with another smaller 50l outside the tent, as I only have 100x100 tent.

GGG Posted August 30, 2021 Share Posted August 30, 2021 @greenkush , looks like a lekker project. What size buckets are you using there and res just the same one ?Sent from my Hisense Infinity H50 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my Hisense Infinity H50 using Tapatalk Buckets are 20L, the control bucket is the same size and my res will be merely acting as a top up to the control when it drops, standard ro water which is a 260L container that was going to be used as an automatic water change system on my reef tank. The top off system will be digital with a sensor that will do the topping of, due to no gravity from res to bucket I top it off like that. I’ll be building a control platform for it eventually with ec/ph monitoring and automatic ph dosing along with nutrients. Will also be adding the chiller most likely end of September.

GGG Posted August 30, 2021 Share Posted August 30, 2021 Sound like a good plan , the chiller would be of great benefit that time of the year , keep posting as you go I'm very interested in this one. Did a RDWC myself with my first grow but didn't have a chiller , turned out good for a first grow thoSent from my Hisense Infinity H50 using Tapatalk Quote Link to comment Share on other sites More sharing options...
greenkush Posted August 31, 2021 Author Share Posted August 31, 2021 (edited) Decided to rebuild the control manifold and a few mods and this is the final product. Currently filling to test entire system for leaks, how I’ll drain it is another days problem. Edited August 31, 2021 by greenkush 2 Quote Link to comment Share on other sites More sharing options...
GGG Posted August 31, 2021 Share Posted August 31, 2021 Yeah draining can be complicated , what is that 2 blue pipes sticking up by your res ? With mine I put a clear pipe on the side of the res to clearly see the level of the water , worked niceSent from my Hisense Infinity H50 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Those two blue sticking up are the outlet and return from where the chiller will go, there are three ball valves on the side (will take a pic tomorrow to show you). Basically the one opens the flow to the inlet to the chiller and then there is one on the main line to redirect the flow to the chiller and the return from the chiller goes through another ball valve into a T back into the pump.

GGG Posted September 1, 2021 Share Posted September 1, 2021 Great stuff , I pulled my chair closer for this one . Chiller will also help that the ph don't fluctuate . That was my problem as ambient temp s go up and down ph also fluctuates .Sent from my Hisense Infinity H50 using Tapatalk Quote Link to comment Share on other sites More sharing options...
greenkush Posted September 1, 2021 Author Share Posted September 1, 2021 I realised I fucked up the manifold to the chiller so will need to redo that later this week. 1 1 Quote Link to comment Share on other sites More sharing options...

I’ll be doing some new clones tomorrow so when they all rooted they’ll go in. Thinking of either pancake stompers, sugarcane or platinum punch… but will have to see. 1 Quote Link to comment Share on other sites More sharing options...

ORGANinc. Posted September 3, 2021 Share Posted September 3, 2021 This is very impressive work bud, I don't know much about hydro, but that is definitely a hat off moment. I'm keen to see some monsters grown here! Quote Link to comment Share on other sites More sharing options...

Batista Posted September 3, 2021 Share Posted September 3, 2021 https://streamable.com/x13ppyThat is seriously epic. Also I see you went hard with the number of buckets-do you have any backup power? That is the only reason why I'm thinking of going coco dtw now.Can't wait to see this! Sent from my SM-A715F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my SM-A715F using Tapatalk No backup power as of yet, will look into a smaller inverter when funds become available, in the interim I'll use a few battery powered pumps (which I have laying around) 1 Quote Link to comment Share on other sites More sharing options...

Really nice set up. The level of the solution in the control Rez will also tell you the level across the system. Digital auto top off is of course better.
