DWC - Pro Build - Advanced Grow

BigDaddyK Ok I have decided that all the things I don’t like about the other hydro systems , I’m going to fix ( or try to ) 1) 19 litre pots are too small , the water level can go down too quick you need at least 15-20 litre reservoir 2) little holes In top are pointless 3) air hose can get trapped by lid 4) emptying is always a ball ache So the solution ? Hopefully here it is To start with I have got 35 litre REALLY USEFUL BOX £15 each - Tested to hold water with no problems , boxes are light proof , lids clamp down with handles ( actually black not yellow ) if anyone wants to point amazon answers this way , you will see what I mean 😜 The second boxes are 45 litre Wham Bam £12 each , these seem tougher , I had a slip whilst cutting , these were tested as above , lids are slightly different with clip handles,bit harder to open . Both boxes will hold 20 litres of solution with an air gap to net pot I bought a 127 mm hole cutter with the little attachment ( to go into drill ) from screwfix approx £15 for cutter and £9 for the attachment ( arbour ) you need to hold the cutter I marked out the centre of the lid and cut the hole , I got a sharp knife and took off the burr around the edge , pot will sit flush Take a 6mm drill and make two holes for the air supply ,one on each side , approx 4/5 of the way up under the handle , making sure this is above any water level you might have , I have added a grommet either side to stop the tube from moving Buy two air stones , the flat ones are best , I have two 150 mm ( 6 inch ) round , flat air stones approx £7 each I have also bought a drill pump , the attaches straight into a power drill , then you connect hose to each end and a few minutes later voila all gone !!! Big thanks to Tim for that one And always remember the BDK golden rule you can always put in ,but never take out in DWC So far I am preferring the 35 litre Really Useful box

BigDaddyK Testing the drill pump , remember the hose always has water in it haha 😂 The reason I use 6 inch net pots , is because it’s easy to interchange between small and big pots , some people use the 10 inch net pots , it’s too hard to start in , I want to be as quick as possible , the more lst or defoliation you do will delay flowering The really useful boxes have a little lip that you can drill LST anchor points , you can still remove lid without any issues, only drill through lid , DO NOT DRILL WITH LID IN PLACE , I used a 5mm drill bit Drilled the lid on the Wham Bam boxes , and dropped two purple lemonade in have also cut the locking part of the lid off , it’s a ball ache to open otherwise 😜 RESULT - the really useful boxes are amazing , the other ones are ok , but these 35litre are the best

BigDaddyK In the other ones too The wham boxes take 20 l of reservoir easily , the really useful 17 l PLEASE NOTE THIS DIARY IS ABOUT THE DWC POTS , BOTH THE PLANTS GROWING ARE ON SEPERATE DIARIES NERE ON GROWDIARIES , ONE IS PURPLE LEMONADE THE OTHER FAST BUDS TESTER 11

BigDaddyK Ok so I’m starting a new DWC project any ideas what this one will be 💡?

BigDaddyK Quick update on the boxes I think this is the middle of week 7 - I had a few issues with the purple lemonades , nutrient related but also as I didn’t notice the water going down , I much prefer the 35 litre Really Useful boxes as th3 root structure is much better , the squarer shape is more suited imo. These are two reliable cheap probes I use . Blue ph pen was from Amazon and the HM2 digital EC was from eBay There is a separate Purple Lemonade diary and a Northern lights diary that’s updated daily if you want to see the progress , and my battle with the nutrients 😜

BigDaddyK Up and running

BigDaddyK Battling the thrips again

BigDaddyK The 8 pot system had issues with root rot , I think it was becaause I forgot to change solution

BigDaddyK This is my pro led setup , 4 x quantum boards , 6 x 150 watt cobs = total power draw 782W from socket , gives 30,000 lux at 5 feet away , as bright as sunlight and mor3

BigDaddyK Okay so this is my new project 19 L really useful boxes with the XL lid Made a clasp by bending a picture hook and bolting on with spacers , you could also use them as anchor points Put in air hole under handle with 5.5 drill bit , might need a bit of extra drilling just around a bit if you get my drift on hole size
