    Drying Questions

    Hi all, I cut up my girls and hung them upside down inside the grow box. They are totally dark, they have two 16w fans that move the air inside but do not point directly at the flowers but move them slightly, maybe the air bounces off the wall but it is really delicate the jet, the extractor set...

    PERFECT Res Temp without approximation?

    Hey Growers! I wanted to ask a simple question trying to figure out what the perfect temperature for water in hydro would be, within maybe 2 F. (I got a new tool that allows me to regulate it without approximation) Let's say i have a DWC - RDWC system, i use h202 to sterilize the water and...

    Power went out while drying harvest

    Power went out and has been out for 2 days now. They are in a sealed dark room and temp is 73 with humidity also around 73. I go in there and it doesn't feel hot or humid. Colder if anything. I have a gas generator and could run the dehu but that will raise the temp and lower the humidity...

    W9 Flower - Temp and/or Humidity trade off?

    For the last couple days I was having trouble managing the high humidity. It was high 74-79% RH and temps at about 77-80 deg. I bought in a dehumidifier to drop the RH to about 50% but it gives off a heat load into my tent. bringing it up to 85-89 degrees. Since I'm towards the end of flower I'm...

    Why do people recommend such low water temperatures for hydroponic root zones?

    I have no experience with hydroponics. According to most of the information I have gathered, the ideal root zone temperature for cannabis is between 26-30 C, which is higher than word of mouth recommendations that I have seen for hydroponics, and is around 18-24 C. Certainly, high temperature...

    How much cold will she handle ? Haha

    Ive been lowering temps steady and Im at 70day , 60 nighttime . I’m doing 36 hours darkness before harvest like I always do, but this time I’m thinking about making the whole last dark period 50degrees. Soil is dried out as always before harvest. What do you guys think? I don’t think it could...

    Best compromise between temperature and light power?

    Long story short. I finally put a proper temperature/humidity sensor in my grow tent and noticed that the temps go a bit over the recommended maximum (~30C/86F) from time to time, specially towards the end of the light phase. I have an 35 litre Aquasystem with 4 plants in a 1,2m x 1,2m x 2m...

    RDWC success - without a chiller

    Hey all. I’m curious to know about those of you that have built/ran RDWC setups and did not have a water chiller, yet were still able to have successful grows. Also, what arrangements did you make to keep your reservoir water temperatures cool in lieu of having a chiller? The idea of throwing...

    Recovering from stunted growth

    I believe due to my daytime-night temperature fluctuations in my indoor garden, I’ve stunted the growth of my two Magic Melons. I’m in the process of adjusting my ac unit to try and correct this but does anyone else know if it is to late? Can and will these plants recover? I’m on day 22 of veg...

    Introducing cold for color. Yield?

    Hey everyone I’ve got some purple haze in a grow box that’s 3 weeks into flowering. I’m introducing cold temps at night low 40s (outside temps from open window) With its genetics, cold temps should change her to purple colors. Would this effect my yield? This is the first time I’m trying this...

    Transplant shock day 1? (Leaf edges curling up/shrunk)

    Transplanted from a 3 gal pot to about an 18 gallon shopping bag, which I’m sure I will receive plenty of criticism for, since it was already over potted in its original container. (Want to grow a massive plant for as long as possible.) Notice how even though there’s more leaves in the first...

    Please help chose AC unit

    Hi all! First of all sorry for the long post, but my grow setup/situation is a little unusual I think so it requires an explanation. My conditions: I grow inside a small grow tent (80x80cm/2,5x2,5 feet), which is inside a spare bathroom that I repurposed for growing only. The bathroom is pretty...

    How can root temps of 18 Celcius (64 F) affect grow?

    I am curious about the effects of cold temperatures on my plants. I am growing a 70% indica 30% sativa hybrid, and I would like to hear anecdotal evidence of possible problems if the temperature during flowering stays at 18 C the entire flowering time. If I yielded 10 ounces in my grow space...
