    Humidity issues at night! Afraid it might ruin my buds.... HELP!!

    What is the temperature at lights out? You already have low temperatures during lights on. What kind of lights do you have?

    Best dwc nutrients

    There is no answer to this. it will also depend on several other things, like your strain, your climate, your starting water, and God knows what more. Maybe you are a very good grower and you can manage your growroom or pH better or maybe you are a shitty grower and fuck up other things and then...

    What political party do you lean?

    I never understood why a country so diverse as the US, did not change their political system along the way. More like the German, Dutch and Scandinavian system with more different parties, a prime minister and a more ceremonial head of state. In any case, it prevents you from getting "but...

    First time making Bubble Hash - 74G total yield!

    Totally understand, but keep in mind I'm also just a recreational home grower with a 12 plant limit. My flower room is 8 plants at a time and a large harvest can be anywhere from 8 - 14 pounds, with a quite a bit of trim. The hash process shortens my dry time from 14 to 7 days and virtually...

    Fast fit flood table alternative

    Which ones did you buy for heatsinks? Do you have a link? And what size of the extrusions would be needed you think, to build the tables? Walmart sells many different folding tables. Do you have a link? @budman410 There are also these corner joints. Then you can get started with aluminum or...

    Co2 usage 2x 16kw 25x25 625 sqft rooms? 50lb bottles/tanks

    You will probably suck the CO2 right out. It could raise the ppm of course, but way less then with a sealed room.

    First time making Bubble Hash - 74G total yield!

    @SuperiorBuds Wow, nice setup! did you buy all the equipment specially for making hash? Or are you using your partner's stuff that is normally used for dry-freezing vegetables and doing laundry? So, do you use ice? Or do you tap off ice-cold water from melting ice cubes? I think you can...

    First time making Bubble Hash - 74G total yield!

    There are several methods and they all have their supporters and their 'proof' to make the best hash. :) One says: You need ice cubes with sharp edges. The other guru says: Make sure to use crushed ice, or even better, only ice cold water. One says: Heat it up once dried and process it further...

    Co2 usage 2x 16kw 25x25 625 sqft rooms? 50lb bottles/tanks

    I'm not always so convinced what equipment manufacturers say. Often they only understand half of what they do themselves. I've read the documents. The story about warm CO2 could be true. But when I also see in the same descriptions that they reduce the heat in the room by applying heatsinks...

    Co2 usage 2x 16kw 25x25 625 sqft rooms? 50lb bottles/tanks

    I do have also a question. It is always stated "CO2 is heavier then air". And this is true. But if you grow on the 5th floor and you would measure the amount of CO2 there, or you grow in the basement and measure it there, you would probably not see a huge difference. So even it is heavier then...

    Co2 usage 2x 16kw 25x25 625 sqft rooms? 50lb bottles/tanks

    Ah, I misunderstood. Sorry. The video is interesting. Although I would have no clue how much Carbon my plant needs. Most plants - as I understand - all contain the same percentage of Carbon anyway. Also I think it is not that important. You just put CO2 in your room and you hope it does not...

    Co2 usage 2x 16kw 25x25 625 sqft rooms? 50lb bottles/tanks

    My calculations were not off. It is just another way to calculate. In my calculation it became clear that 60 lbs of bottled CO2 = 20 Lbs of LPG turning into 60 lbs of CO2. So that is 1:3 The 20 lbs CO2 in bottles contains 27% of Carbon as the video shows. The 20 lbs of LPG (a mix of butane and...

    First time making Bubble Hash - 74G total yield!

    So the right order for bags is 120 - 73 - 25. An the right order for work is Putting bags in bucket - wash - smoke. And not 'smoke - Putting bags in bucket - wash' :)

    First time making Bubble Hash - 74G total yield!

    What some people do: They buy extra buckets and cut off the top part. So that you are left with a ring of about 20 cm. They fold 1 bag over 1 ring. In the bucket you first place a loose bag (with the smallest mess, for example 25). Then you put the ring + bag (with a slightly larger mess, for...

    Control odor & sterilize your room air + surfaces 24/7 + eliminate PM

    I do think that Powdry Mildew is a mold. It is a funghi. https://en.wikipedia.org/wiki/Powdery_mildew There is no simple sollution to prevent or beat PM. The winegrowers in France suffer millions of damage every year thanks to PM. If there was a simple solution, they would use it every time. PM...

    UV-C to prevent Bud rot and mildew

    I agree that a good filter will help a lot. Also being more careful of what you touch before you go into your room. But as OldMedUser already said: You have to get into your room. Not many of us have lab-type chambers.

    UV-C to prevent Bud rot and mildew

    What is this pic about. It looks like UV light, but what were you doing? And how (if) would you work with UV light to prevent bud rot? I know handheld devices exist. But with something that can stick around 24/7.

    UV-C to prevent Bud rot and mildew

    I don't know. The fact is that in hospitals it does seem to work. But which bacteria, spores, viruses exactly ... I don't know. In my country, we have an agricultural university that does research on it. But their results are not yet very clear or unanimous.

    UV-C to prevent Bud rot and mildew

    Very interesting! I also tried to find research papers about the subject, but there are not that many. Most reports come from companies that manufacture UV-C and ozone devices for greenhouses. But what most of the time is lacking, is good scientific research.

    UV-C to prevent Bud rot and mildew

    The product that I showed, the UVPro 50 is not a ozone generator as far as I know. Because then they probably would have said so. On their website is also not detailed info about the bulb or about a spare lamp. Fuckers :) A little bit on ozone in the room where you work is also no problem. But...
