Wil it still oscillate when it is horizontal?

Did any of you guys try out if the monkey fans can hang horizontal? So that it blows straight down? I heard it might be bad for the engine, but I have no clue.

Climate (which you can see as VPD) is just as important, if not even more important then light. Of course when the light is totally shit, nothing helps anymore. But even with not so good lights you can grow a decent but, as long as you have your climate in order. In general: what most people...

There are lots of circumstances that can influence your VPD. But the numbers... how did they come up with them? With cannabis there is also another important factor: Although bud rot en mildew are not caused by high RH, it sure can speed it up. So although a lower VPD would be better for growth...

Now you made me curious :)

I am still looking for a scientific source of the VPD numbers for cannabis that you see around on the internet. There are studies done on several plants, like this one for example. Ideal VPD-numbers for many plants in greenhouses are lower then the numbers you see in all the charts about...

I would suggest Yara Actisil for a foliar spray. Actisil is the one I have experience with. But I can not find it on the Yara USA website. I will send them a mail today and ask if they have it in the US as well, or if they use a different name for it. (The Yara site is down for a few hours...

Not sure if you already use any silicon product. @Renfro does (I think) Of all the 'amazing products' this is perhaps the only one that has a proven and scientific background. It helps roots and stems to become stronger for example, and in that way plants are also less vulnerable for bud rot and...

Be careful not to drill through the coolant pipes in the sides. I'd like to know how to detect it.

it depends on the material. You will have to find it out by experimenting. Laboratories use a thermometer in their material and they have a certain calculation. Way to difficult for me to understand. Dry ice in a freezer might do better. Never saw it. But when you use a deep freezer, how will...

I saw that video too, but there is more to freeze drying then he shows. He forgot that in a professional freeze dryer the material you want to freeze dry is heated when the machine starts running. But you can not heat it too much. He oversimplified it a bit. And keeping the one chamber cold all...

Your room looks like everybody on this forum would like to have it: Big and clean! I think that in the future you could change to nutes from professionals like Peters or Yara. Way cheaper, and you can adjust the nutrition and different elements much better to the needs of your plants and your...

@DoubleAtotheRON Wow, man! You are amazing! Thank you so much. Corona didn't harm your empathy and kindness. That's for sure!

1 cola, huge yield per 4 x 4 and flowering time of 8 weeks.... every growers wet dream!

And it is soooo expensive.

Next time when you are using the Greenbroz trimmer, would you be so kind to do some measurement for me? For sure you do have a device like this: Hope your recovery from Covid-19 goes better and better!

I saw a video of the Ultra Trimmer. Same principal, but instead of 2 turning blades, it are 2 horizontal surfaces. The slots on the Ultra are wider. As wide as a pinky. And in the video you see the owner has a fingertip missing. 1+1=.... But the slots of the Greenbroz seem more like 7 or 8 mm...

I know that once plants have roots in hydro, it doesn't matter if you achieve maximum DO by bubbles, flooming, waterfall, etc. But I was curious if it would be the same with just stems. Is maximum DO in the water sufficient? Or does the moist layer of air that hangs above the water surface also...

I guess you use an air pump. You think it would also work with a waterfall?

How deep are they in the water? I mean, is it just the tip and does the stem get wet by the splashing? Or are they in the water for an inch or so?
