If aero would give better yields, or more harvests per year, or be an easy system, it would be used by commercial growers of herbs, plants, vegetables, flowers. But they hardly use it. It is used sometimes when there is a lack of space or a lack of water. And with some specific plants (I do not...

Wow, different countries, different rules. Where I live it would be shut immediately. I also worked with CO2, and noticed that it got me a bit more tired if I didn't turn it off. (But I have the same in a house that is not well ventilated.) My generator ran on natural gas. Really cheap and not...

But if the sell shit like this, then they can keep their product. The pis from their website. The only ask $ 80 for it, (I guess that is Canadian dollar, which is about 60 in US $) for an ounce, but still.

Just an example, but your bandwidths are very wide. With a humidity of 45 and and a temperature of 80, your VPD is above 1.5, which is quite high. With a humidity of 50 and and a temperature of 65, your VPD is around 0.8, which is low and ideal for rootrot.

Of course everyone has to learn things. But that does not mean that there are not questions that make no sense at all. If you want to know how long it will take you to drive from A to B, you can do the math yourself (will you be on a bike or in a car?) or use Google Maps. You don't go on a...

Advice: When working in the room, turn it off for a while. Where I live for example, the maximum in a classroom is 1200 by law. 1000 is the max for schoolinspectors. In offices it is also 1200 and only if there are some special circumstances, you are allowed to go temporarily to 1500. And: All...

2 things: - Why is this an important question? - Did you never go to school and learn how to do math? You know how much your light is; you know for how long you will run this light. You know what extra's (fans, exhaust, pump, etc.) you have. And hopefully you do know what the price of...

Buy a better brand. I have a Bluelab. Almost never have to calibrate it. I check it of course, because I want to be sure, but almost never have to calibrate it.

Try again. The pics are less then an inch wide

And why is that, you think? I am not saying it will, but you are very sure, so I was wondering why.

He says in his post that he got cuts from a friend.... I think that experiment was not done well. It sounds like bogus. I know plenty of people who have large pots with several plants in them. Never heard any problems (at least not about getting males/females)

The Blue Energy is already tested in the Netherlands. Where a river (sweet water) is meeting the sea (salt water) they builded installations. It is still in an experimentel phase but it looks good.

But you do have aisles, right? Are you not afraid to waste to much light? Shining at 'nothing', only the concrete floor?

For sure it works, but at what costs? Lithium-Ion is just not the technology for powerplants, cities or neighbourhoods. What is also smart of Tesla is that they saw the potential of home batteries much earlier then others. And their design is great. But the price is outrageous, and it will not...

Silica is perhaps the only additive that almost all growers agree that it does make sense. Commercial growers also use silica. As a foliar feed and in their rez. There are many scientific papers of what silica does. I used silica as a foliar feed on my clones and I saw a difference in a side by...

If your room is not sealed, it is totally useless to add CO2. Wether it is with bags, breathing, tanks, generators. Turning off the exhaust fan to prevent the CO2 getting sucked out, will cause the humidity and temperature to rise. If you would have a sealed room, then maybe if you would...

That is the typical Tesla marketing BS. That South Africa fell for it, perhaps has to do with the fact that Elon Musk is South African. Building a battery that size in this way is not the future. It is a marketing stunt. Besides Lithium and Ion, you need huge amounts of Nickel and Cobalt...

Yes, but it will take a while before that will be on the market. and then you have to wait about the costs. 29% is already impressive, and they are ready to go to the market.
