    Imagine that.

    nasty? i dont see how.

    Potentially dangerous? ofc but it's potentialy dangerous to drive a car as well. as long the wool is moist, theres no danger.

    replace it every run or not, you can reuse if you wish.

    i understand you prefer your method tho

    When it dries out it's a great way to get silicosis. It only takes once...

    Not here to start an argument. I found RDWC and hydroton pebbles to be indefinitely reusable and friendly.

    Another option is to frame the area in and use a pond liner to catch spills.

    This is a good idea in general, there's always a way to have leaks you didn't realize- until the system shows you!

    Exactly! No matter how much you prepare, and no matter how solid your system, water on the floor is inevitable. A lot of times it's from human error.

    This is an example of how some things look better on paper, but falls apart, or isn't feasible, in the real world.

    If you could post some pics of the results of your grow, where you've used these methods you're describing, then that's one thing. But if you're just sitting here throwing out unproven theories, then you're talking out of your ass!

    Do you even know how to grow inside? Have you ever grown?

    And by the way, @rkymtnman isn't short for "Rocket Man"! It's short for "Rocky Mountain Man"! You, being a "member" do not have a lot of weight when it comes to challenging one of the legitimate "Well-known Members" who has many grows, and a lot of experience, success, and and failures under his belt! Someone who can give good advice, based on experience, not ill-advised hypothesis that confuses or misguides others.

    It might be better for you, and better for others, to do some more reading than posting

    Bout to start my rdwc this week. Wondering if I should clamp those fittings now. Way i see it is I needed extreme force and vegetable oil to put them together, surely they shouldnt pop loose due to water pressure.

    can i add:

    - check plants daily for air pumps as well, roots without oxygen cannot go more than 24h without having some stress

    - always have in your house new spare pumps. the few bucks/euros/pounds they cost are well worth the added value of having a replacement in case they fail (and they do will fail from time to time).

    Look at some of the pumps in favor with aquarists. Some have nice features like soft start, or the ability to be air-cooled.

    Make every precaution you can to have the least amount of fittings, connections etc as possible. The less you have, less places to develop a failure or leak. Always keep extra pumps, fittings, grommets etc on hand. If you can, build a system that is housed above the reservoir like a tray above a tray etc. Then if/when a leak occours it will only leak right back into the reservoir. Make sure you level everything a few degrees so that it will always drain where it should no matter what.
    When it comes to pumps, you basically just have to put faith in your pump and the brand that you choose. I've had no worries leaving my grow for days at a time. My only restriction was my res size and how much extra I can add to give me a few days away not handcuffed to the hydro system.

    OP here. Well, it happened again. It seems my pump (Boyu or some shit) likes to stick. Dam glad I made the habit by checking-up every day! Switched off the 600W hps and misted plants, door is ajar so dimmer sunlight can still come in to maintain photoperiod state. They have started bouncing back, and I'm glad its really only a test crop. Guess I'm in the market for a better pump!

    As counter intuitive as it might sound, continuously operating your water pump tends to be more reliable because there's no stop/start cycling.

    HydroLynx Active Member

    yeah I thought too. But that defeats the purpose of my flood n drain feature. I do ask myself is that extra lil bit oxygen worth stopping the pump...

    ttystikk Well-Known Member

    Consider a smaller pump and a bell siphon. This combination would continuously flood and drain the table while the pump runs nonstop.

    Nah. I use the pump-pipe to drain and/or overflow plumbing to drain my growtubes. Basically just at night it cycles on/off every 30min. When the res drains back, ideally/hopefully soon my arduino can take accurate readings and actions, eg res volume, EC, etc. While that happens, the roots should be exchanging gases quicker, in theory.

    Pump on:
    Pump off::

    Are you aware of what a bell siphon is and what it does?

    dstroy Well-Known Member

    Sounds like a fun project. The atlas scientific stamps are easy to integrate, you can get temp/EC. I bought a bunch of float switches on eBay for pretty cheap.

    HydroLynx Active Member

    I think it drains a grow-tub periodically with continuous pumping, if I understood the concept right. I prefer the elegance of basic flood n drain plumbing.
