Would DWC systems perform any better by having a bit less water and more air after a large root mass has formed? Possibly with a small fan pushing air into buckets at a considerably higher volume than air stones... basically having the plants get oxygen from air instead of DO from water? I...

Would be interesting seeing a full grow where this is done and having some plants not poked as a control group.

After a bit more learning, I think I'm going to try Cap'n Style instead of RDWC. It seems like it will be a bit easier for a first grow with similar results.

How does the hospital get stuck with the bill if the people don't go because they're afraid?

A parent is to provide for their child, not society. Although there are ways for society to help that child without the government mandating anything as has always been the case.

Covering pre-existing conditions without charging more for that condition is not "insurance". Insurance is for unexpected events. If you have health conditions that require you to seek a healthcare provider more than most people, you should expect to pay more than most people, whether that is...

High deductible health insurance was affordable. Combined with a health savings account it's a very good option in as much as what health insurance should be (covering the costs of unexpected health related expenses). The ACA got rid of those plans. Hospital fees are outrageously priced. Go to...

Only a retard like you would need two separate posts to respond to a one sentence comment.

Trump is going to win 2020, the Democrat party will not unite.

I'm looking for the best venturi design for micro bubbles. So far this is the best I've seen, has anyone seen better?

Real OGs died before you were swimming around in you dad's nutsack, you couldn't have made one jealous.

You might consider two of the 4xQB132 packs and a HLG-320H-C1750A. That driver could power 5 QB132's up to 72W each when cranked up to 2A. That's 360W for 12.5 sqft, or 28.8W per sqft. It is over your budget, but you'd be left with 3 boards you can use for a veg tent in the future with...

Thanks, now if I can just get electricity to my shop so I can get started on this project.

Thanks guys, I suppose since others are running QB's in parallel with CV drivers without problems, I shouldn't have problems either, I was just worried about things I've read regarding LED's and thermal runaway. I will adjust amperage to 8A while driven and I will also match the boards so that...

Is the 2A rating on the qb132 the most it will ever try to draw, or the most you should ever make available to it? If 2A is all it will ever draw, then I don't think I'll have any issues. If 2A is the most I should make available to it, then it seems like I could have an issue. Do I just need...

Hi, I just ordered my first lights for my first grow. I originally planned on getting some Chinese blurple lights, but after a bit of reading, I opted for QB132's. Unfortunately, I think I may have made a noob mistake and ordered the wrong drivers, which I cannot return. From reading around the...
