Nutes = food Do you need food?

If you have head room issues, work on a lower profile style growing than using buckets. Not to steer anybody away from DWC or RDWC but you can build an aero system that sits much lower than buckets or look into NFT or ebb and flow. You might also want to look into scrogging, that saves a ton of...

While I agree about the corded roots, did you read the article I posted? I've found that when the water levels are kept high during veg and pre-flower, I get fine roots not cords. The plant keeps that root formation even when the water level is dropped after that period, essentially during weeks...

I posted this link a while ago, it's a pretty good read. http://urbangardenmagazine.com/2010/11/qa-water-culture/ Since I read the quote below, I've started doing this and have seen significant increase in trichome production. Essentially, I have a higher water level ,1" from bottom of net...

Sorry to hear about the CD. My guess is that the sun beating on your res boiled your roots especially if you have a black bucket for growing. That water probably hit 100F+ and just like you thought, poof, no oxy and that's all she wrote. Best of luck holding things together during the build!

Check out post #298 in this thread for the pictures of mine .https://www.rollitup.org/dwc-bubbleponics/366114-official-dwc-cooler-club-any-30.html I call it a folded RDWC, the bubbler bucket in inside the reservoir to save pace and keep it cool. I currently have two of them running and they...

Depends how many clones you want. I like to take 4 when sexing, so I wait for 8-10 nodes and top the plant. I let the bottom branches stretch to about 5-6" and cut them. That way if something goes wrong you've got at least 4 more cutting to work with.

That's what I do all the time but with 3" and 6" pots. I just stick two 3" net pots into a 6" net bucket lid and fill around with hydroton. I always grow two plants to a 5 gallon bucket.

Interesting. So, essentially it's a tubular sea of green? I'm wondering what the differences between trays will be in regards to their position at the light source. I've seen something *similar-ish* using several 4' VHO fluorescent bulbs mounted vertically but never with an HID.

From seed? How old? Before I flowered those, I'd top them and throw some breeze at them to, they look a little thin.

You're about three days from really knowing, you got a case of the impatients. Right now it's *probably* female, how's that?

You've got it exactly! It's really simple to do. I'd get a pump of about 400-800 l/h and put a valve inline to slow it down if you need to prevent overflow. In that third pic, I'd drill a hole on the side opposite the float valve, put a watertight fitting in it and run tubing to the buckets. In...

The size of the container and plant are directly related to how many cutting you need at a time, remember that. If you're trying to get 50 cuttings a mother, you'll need big fat momma's If you're doing smaller grows, make your mom's an appropriate size. I also do new moms every couple of grows...

Are you running different strains at different growth stages? Off the top of my head, I'd have to say that some of the plants are taking in elements at different rates and without a recirculating pump there isn't enough flow for everything to equalize. There's a simple fix to your problem but...

Yeah, that's mine thanks. It's actually a "folded" RDWC, there are pics of the Franken-cooler in the "any kind of cooler thread" in the DWC forums.

Quoted for mad truth! I grow hydro but keep bonsai mothers in soil. Never keep all your eggs in one basket.

Unless you grind it up and smoke or snort it, the chances of getting cancer from polyvinyl chloride piping is less than your chances of getting struck by lightning while winning the lottery. Be serious people, there are a lot of things to worry about but cancer from PVC is way down there.You...

When you run water through an RO membrane you strip ALL the minerals out, making it soft water, which in itself has no buffering capability. Cal/Mag adds calcium which is a big buffering agent. I know that my GH nutes drop like a stone without Cal/Mag, so that's *probably* your problem. The...

You're going to have to find a happy medium, let one go long would be the best bet. Then harvest the other a little early and you've got two different highs from the same grow.

I don't know anything about those nutes or their buffering capabilities, so I'm going straight to basics. The first thing I suggest is to make a gallon of solution, just like you were going to use it, test it and then drop an airstone in it and let it sit for 24 hours, then check your pH again...
