      Great video straight to the point.
      How does CO2 affect the optimal temperature? Since the most efficient way is to slowly increase CO2 EC and PAR... would be optimal to do the same with temperature or keep it at some point?
      Thanks!

      I think the technical aspects,was ott,as to contemplate reaching that levle of technical pro-ess with a grow,you should have alot of grows under your belt,and if you don't know by this time about your plants,rather than seeking this level of technical input,I'd stop growing! I think your optimum audience is better aimed at novice grower's,with a lower technical aspects,

    I love that youre usimg a pier reviewed paper. I took 4 mycelium and coco bags and opened them and put them in a tote. Now i just feed my mycelium oatmeal. The co2 stays at 1750 as suggested by utah state Bruce bugbee and harvey from npk university videos. The relative humidity is in the high 80s and so i need to vent the humidity off while retaining the co2. So enter the dehumidifier. Now i have a terarium powered by led only light and mycelium farmed co2.

      MIGRO all the led lights I have seen say that they need to be switched off after 5or6 hours off use & need to cool down for 20 mins are they all like that ??? so for a 600watt bulb I would need 4 300watt 3leds lights and alternate so some can rest is that the idea or can u name a led lights to replace my 600watt 😎🌲

      Hello. You don't need to switch off LED lights to cool them down and you can switch them on and off quickly.

    Co2 is heavy therefore falls to the floor. If you have your exhale co2 bag above a fan , it will be spread throughout your grow tent BEFORE being sucked through your exhaust , therefore it does not need to be closed circuit.

    Hi Shane. You do great work. I totally find your videos comprehensive and easy to understand. The heat gun trick, awesome! I grow my garden outside for almost 4 months. I start my plants in early June and bring them inside when the Autumn rains come. The plants are 5-6 feet tall. This year 13 plants! I grow them in 8 gallon grow bags so they are movable. Going from real sunlight to LED. I have 5-6 years of this method, Always successful. But I always worried about light burn and setting distance. You just provided me with the tools to set this variable, thank you, thank you, thank you.

  • @NinjaRastaMon
    @NinjaRastaMon 2 года назад +1

    A hard to answer question for me is the optimum 850 max par study and if it was done on a 12-12, or an 18-6? Also if 12-12 is max 850 par than can I run 8 on 16 off at a higher par for the same DLI level? (est 1100-1250 par). For now I just leave it at 11 on and raise it to 850, then taper down to 10hrs in the last two weeks for natures DLI curve to preserve terpenes. I use 12-1 and it recommends 8 hr flowering as cannabis is a short day flowering plant. But then DLI and this max 850 par has me wondering if its possible without co2, as cannabis grows at night and can benefit from longer nights, while studies show it's done taking up light after 8 hours.

    I will have a tent setup indoors but there is no way to do ducting and getting the external air in or out directly from the tent. So my question is would it be ok to just circulate the air in and out of the tent indoors? The house itself is big and the people living in it providing co2 with additionaly multiple daily opening of the windows with fresh air should work right?

Indeed, a doubling in CO2 concentration increases crop yield by 30% or more, in experiments conducted under close environmental conditions such as green houses and growth chambers (Kimball, 1983a, b; 1986; Cure, 1985; Poorter, 1993; Idso and Idso, 1994)."

    Do you have any advice on maintaining these relatively high temperatures in cool climates? It seems impossible to heat air (cost)effectively when you're expelling it once a minute.
    When you do recirculate air, say your intake and output are connected to the same indoors and heated room, would that not cause harm or stress to the plants by lack of actual fresh air?

    • @MIGROLIGHT
      @MIGROLIGHT  6 лет назад +2

      Even the most efficient grow lights emmit 50% heat. There is plenty of heat can be used to keep the temperature up during cold periods. Extracting low in winter with a high inlet will help. However during cold periods you are correct you must lower the extraction rate to maintain temperatures.

    Intaking air from inside an occupied building might be good during light time but sure it is bad during dark time. The best balance comes to intake from outside no matter what the outside conditions are. If you you have your room/tent set up properly it will autoregulate easily.

      Why is the air bad at night?

      @@MIGROLIGHT During light time more CO2 is needed thus intaking from a room might be better than outside. During dark time more O2 is needed thus intaking from outside would be better.
      Usually its better to intake from outside as O2/CO2 balance during day/night is better for the plant than inside air balance.

      @@arnauvizcarramiserachs6318 It depends a lot on the outside. Your breathing create a lot of co², 1000 ppm is not rare especially on winter with windows rarely opens. So intraction from a livingroom is the most effective way (except co² bottles in closed room/tent).
      But even in that situation, 1000 ppm = 0.1% while O² is about 20%, so I think the plant has plenty O² at night.. I will check this to be sure.

    A question: In a closed environment with plants, does raised levels of CO2, in itself, lower air temperature? This provided the input light energy is constant. Thanks!

      Co2 isnt necessary unless the light is hot which would be from high par. It will heat the leaf and bud regardless. You want to add co2 in buding stage if you have a nice high par light. Check leaf temp and keep your leaf temp about 80 humidity 70. As long as your leaves arent stressing your golden. Keep your pots between 68/72f at all times.

    I'm pretty sure you can fill a 10x10' room with CO2 and it would take a good 8 hours for the plants to lower those levels to atmospheric. You don't NEED to remove entire room volume every minute... thats required in a lab/clean room maybe... not around some plants I don't think. Mine seem to grow fine anyway with just a few full exchanges of air per day... then I can keep CO2 high in that area for a good 8 hours a day.

    I think you forgot about humidity because that along with temperature control the rate of transpiration. You can have everything else perfect but if you mess up too bad on the VPD you will fail to succeed with your grow.

    Funny you should say about bringing natural higher levels of co2 from people sleeping in the same building as a place in london out performs a place in the suburbs both same set up and same plants except, suburbs = 1800 to 2000g london one 2000 to 2400g all ways breaking records down there ,and I put it down to higher co2 levels as london is highly populated

    From an HVAC point of view 1 air change per min makes no sense. What about lights off when plants dont use CO2? Or the humidity or temp outside are highly out of spec?
