Great looking roots! And so many. That is why I asked. Do you perhaps know what the temperature of your water is?

@BobBitchen Did you use any kind of hormones to get these roots? And did you use plain water, or any nutes or something like that in it?

Of course you make more money when you have more harvests per year. But if your labor costs increase, it can also cost you money. If the chance of damage to your plants increases, it can also cost you money. If you turned the veg room into a grow room, you would earn (some) money. If the area...

You will have to find a balance with vegging: If you do it in the same room, it means less work (tomato growers in greenhouses do this), less stress sometimes. If you do it in separate rooms, it means better control (climate) and less space wasted.

The development of root rot can have many causes. Temperature is just a trigger for some types of rot. What I would advise you in any case is to clean your system very well after a run. And not with a sponge and some soap, but with materials that are used in professional agriculture.

Perhaps it is better to first learn how to walk before you can run....

You don't see it because there are much simpler, cheaper, less faulty hydro systems. Same reason you also hardly see low or high pressure aeroponics in commercial grows. Too complicated, to expensive, too much devices that can break down, too much maintenance, too labour intensive. And the...

@Jhef Why do you open 2 similar posts?

Where there other strains that you experimented with? Do you have any growreports of grows with such huge yields? Searched for them, but couldn't find them.

It has never been tried for a good reason: Because it will not work. And you can say: "But it has never been tried, so how do you know that?" And I will reply by saying that all systems where people have total liberty, those same liberties will be abused by people more evil, more smart, more...

The Government is nothing more than the representation of a large group of individuals. Namely we the people. So basically free individuals already have the power and make the decisions. Libertarianism is a beautiful theory (just as communism may even be a beautiful theory :) )...

Off topic: You may also ask yourself whether you need such a tight bandwidth. Make it a bit wider and your problem is also partly solved. Sorry, this is not an answer to your question, but only meant as an informative contribution.

Used successfully ... I doubt't it exists. But countries or regions where it was applied in practice do exist IMHO: Somaliland and parts of Congo.

Did you buy the seeds? Back in the day they were around $ 100 for 1. Is this still the case? In what way is it soo much more work taking 20/30/40 cuttings then 10? Sure, in the beginning you have to do a bit more work, and you need 2, 3 or 4 motherplants perhaps. But once they are in their...

But it is research done by the manufacturer. And maybe I'm a bit too suspicious, but I don't always have a lot of faith in that. Not because they lie or withhold the truth. But because they often don't do proper research. Or because there are other factors that influence the research. I would...

Still, there are no commercial growers (exceptions of course) who will use either dwc or rdwc. Too much hassle, to complicated, to much problems. There are growers who use large basins to grow vegetables and herbs on styrofoam boards. Some of them use venturi. But that is most of the time for...

Commercial growing and DWC don't go together. Perhaps if you grow herbs, but even then there are simpler hydro methods.

Why use soil at all? IMO a commercial grower has more benefit by a clean medium that he can control. But even with a device to prevent Botrytis and Mildew, you shouldn't push things to the limit. Firstly, not much research has yet been done to what extent oxygen compounds actually prevent and...

Then I think you have a different understanding of what penetration means.

We are not lighting tunnels. COB's don't penetrate the canopy better then boards or strips.
