    With timed dripper systems and flood & drain systems does the medium ever get dry? I ask because my reading suggests that cannabis medium should get dry between waterings. At least that's my perception of the information. But if there is simply a timer and no micro-management of the grow it would seem that the soil is likely to be always wet. Soil that's always wet = overwatering, which we all know is "bad."

    Please help me with this apparent contradiction. Thanks.

    Be carefull with cheap meters, that most of the time giving you false numbers and this hurt more than help. My hanna meter was broken at a time my economic was in resecion and I tried one of thoses yellow meters, and it made my crazy, that was a pack of two, one for ppm and another for ph, and the ppm one give me the reading but the number were the half of the real one, and the ph meter read 9.8 in the tank but I got a sample from the tank with a cup and the meter red 5.7, and was the same meter and the same water....

    No it shouldn't ever be "dry" They cycle it because it doesn't need to be drenched 24-7. And the longer you run the pump the hotter it gets and the harder it is to keep the liquid cool.

    Nice rdwc setup. Looks nice! I drain mine by putting in a small pump into the control bucket and just pumping it down the drain. If I'm just doing a rez change, I don't worry about the residual water left over and if I need to empty the entire thing, I pump the water out then use a shop vac (wet/dry) to suck out the remaining water. Actually works really well. Are you going to use an air pump, or just waterfall method? How about a chiller? I would suggest wrapping your pvc pipes and buckets because they allow a lot of light to make contact with the water and it will cause pathogen issues. I used panda film for my pvc pipe and have black buckets. When I modified my system and put the control bucket on the outside of my tent, I noticed a glow coming from the pvc. I then realize the pvp pipes were acting like giant glow sticks which made keeping bacteria under control a more difficult issue with a chiller and hydroguard. I personally would put duct tape around the clear tubing as well. Need to keep the water system super dark. Looks great, I hope you grow some monsters!

    Awesome dude! All great points and i will tend to those immediately
    And yes i will be using airstones also.. im mimicking @medgrower1 on YouTube i thought it looked pretty interesting.. and i was also thinking shopvac if i really felt the need to really clean out each bucket .. which i hope not because their practically siliconed onto the grommets..

    Glad to help, I went through all the issues with a diy rdwc system myself. Make sure you use a sterilizer or a beneficial to keep root issues under control. A wet/dry vac is a must for a hydro grow, also, imo. I used some 2" rubber couplers from lowes to join the system, so each bucket can be removed if needed and can break down quickly too. Just got to block all the light and keep the water temps low (mid 60's). I used to have round 5 gal buckets, but they were prone to leaks with uniseals, they did work though. I changed to 8 gal square buckets recently and put the control bucket on the outside of my tent along with the air pump, water pump and inline water filter so I can access all of that without opening the tent up. Here's an image outside of the 4x8 it's in now.

    And your set up looks great.. goals..... i wana get mine like that but with ten buckets.. after i practice hydro and get down the fundamentals i will probably make that next step to 10 square 8 gals

    I love hydro, I think it's a lot of fun and easy once it's dialed in. Lots of great info in the hydroponics dwc section if you are ever looking for specific help. Can't wait to see what it does for you!
