    Res/Nutes Change Frequency

    Ah, I think I misunderstood your earlier reply.

    Res/Nutes Change Frequency

    Why is that? Because you want your EC to slowly increase during your bloom?

    Res/Nutes Change Frequency

    Perhaps you also have the answer to this then: Dr. Daniel states this: In a normal recirculating setup the EC of the solution in the main tank will tend to increase with every irrigation while the total volume of the solution will decrease. This happens because healthy plants always absorb more...

    Res/Nutes Change Frequency

    This is what Dr. Daniel Fernandez said about the subject: Add in-line UV filters and carbon filters. It is fundamental to ensure no microorganisms contaminate your nutrient solution. For this reason, online UV-filters are necessary to keep the nutrient solution as sterile as possible. Carbon...

    40+ lbs with 12 Plants in 2 Rooms on a Flip

    He also disappeared. If such people don't get the credits and applause they hope for, they often vanish. You can see that happen on many forums.

    Small industrial de-humidifier?.

    I assume these are the numbers listed in the manual. These are usually based on ideal circumstances. How many liters do you actually get from the air per day?

    Still no independent review of the GeekBeast Pro???

    A difference of just 1 or 2 degrees under led is not very common. These numbers you will have with HPS. Under LED, it will rather be a difference of 3 or 4 degrees Celsius, and this only if you manage not to extract all the heat directly. Otherwise, the difference could be even higher.

    HLG 550v2 - VS - Alibaba light

    @thewinston never came up with anything to back up his story. So probably all BS.

    Perfect mother plant

    My big fear is that if you have a pump failure or something like that, your motherplants are gone. With a motherplant on soil you have more work, dirt, chance of underwatering or overwatering, and other things, but it feels more safe.

    Res/Nutes Change Frequency

    My English sucks, so does my Chemistry :) I meant more something that you can compare CO to CO2. The first one is very poisonous. I thought perhaps something could also happen to an element in the nutes. But again: I have no clue at all.

    Perfect mother plant

    Do you run your motherplants also on flood & drain?

    24/0 lighting & temps question

    Why did you want 24/0 in the first place? Your numbers are jibberish to most of us (at least to me)

    Who runs Bloom temps over 79F regularly?

    I think you are doing great. It now comes down to fine tuning. Getting more and more info. Not only from this forum, but also from commercial growers who grow other crops and scientists. The knowledge is there.

    24/0 lighting & temps question

    No. It does not work that way. It would still take the same amount of time. And it would cost you also the same amount of electricity. At least... if you do it right. Perhaps that is what is also wrong with the TO. Maybe he gives them to much light, or at least to much heat. Let's say you have...

    24/0 lighting & temps question

    24/0 can really help if you want to have a stable climate. It can be easier to maintain. But when that reason is gone, I wonder what is another reason to keep your plants on 24/0. Marihuana is a C3 plant (like 95% of plants) and it doesn't need darkness to grow.

    First time trying a 3000w LED

    The UK, the country that still uses Stone, Pint, UK Gallon... that kind of progression?

    First time trying a 3000w LED

    Don't you think it has to do with how the dates are set? Is it month-day-year or day-month-year? You 2 are in the movie "dumb & dumber 3"?

    24/0 lighting & temps question

    Why do you want your lights on for 24/0? Most people who do that, do it because it gives them a more stable climate. But you apparently do not have a stable climate with it at all. so why continue with it? What are the benefits of 24/0?

    Res/Nutes Change Frequency

    There is also something that is called the build-up of plant exudates, which can be toxic. I do not really understand this. Are they the same elements that were already in the nutes, but now disproportional? Or are it new elements, created by chemical reactions inside the roots or plants? I suck...
