    resivour size

    I use a 10-gallon reservoir for my 4x4 flood drain table. However, I top feed and let gravity drain back to the reservoir. Less water = less nutrients = less $$$. Every 4 hours the pump turns on for 3-mins.

    Jack's 321 or me?

    No. I never had the need to. Funny thing . . . I'm more precise in measuring the Jack's since it's granules and weighted by grams on a scale. I was fairly accurate with the AN but not nearly as precise. I even went and bought a 'scientific' certified scale to ensure Jack's is dead on the $$.

    Jack's 321 or me?

    My 'runoff' gravity drains back to the reservoir. The EC after a fresh nutrient change is 2.4. I check it daily and it doesn't move too much in either direction.

    What do you recommend for my target EC? These were small clones 3-weeks ago.

    I don't think the EC is too low or too high. I would expect too low or too high to be reflected in the attached lab report. Correct? Looking at the tissue sample lab report, there aren't any deficiencies noted. For the most part, everything is within acceptable ranges. I have 2 Ph meters...

    Jack's 321 or me?

    My Ph out of the tap is a little high. However, I adjust and keep it 5.8 - 6.0. Most often, after mixing a fresh reservoir, the Ph settles in right around 6.0. When it fluctuates a little, I will adjust. But not too often. It's pretty stable.

    Jack's 321 or me?

    Just to clarify: I've been feeding plants using this EXACT method (hydroton, Air Pots, top feed, and drain to reservoir) for the last 2 years without problems. The Air Pots drain very well so the roots aren't sitting in water. If the EC is too high, wouldn't the tissue sample report reflect this?

    Jack's 321 or me?

    I'm new to Jack's 321 and have some concerns: I have the sealed grow room dialed in almost perfectly. Humidity, CO2, Ph, PPM's, temps, lights, etc... are ALL well within the recommended range. The nutrient solution is chilled to 65 degrees and the EC/PPM's are EXACTLY as recommended by Jack's...

    12k mini split is it enough?please help

    If it's below zero outside, you may need to heat the room at that point! Gree has an AC/heat combo for both.

    Who REALLY Cures PRIMO?

    And worth EVERY $$ !!! I cannot believe how simple the dry/cure process is now. 100% damn near PERFECT! My very 1st batch was amazing. I took a sample to a local 'OG' and he refuses to believe that I got the bud anywhere but a dispensary. Crisp on the outside yet spongy when squeezed. Not...

    Dehumidifier for an 8x8 room

    I paid $1k for the Q70 shipped. The Q105 is almost $2,500. Those extra 150w cost me about an extra $20 a month. It will take 75+ months before I save $$ with the 105 vs the 70. I made the correct choice. I've also been burned by 'home' versions of the following: dehumidifiers, humidifiers...

    Dehumidifier for an 8x8 room

    I have about $12k in my room. I look at it like this.... at ANY given time, I have about $6-8k worth of medicine in that room. I protect that investment with a mini-split AC and a Quest dehumidifier. The meds are not any good if they have mold/rot, pests, etc... your return on investment is...

    I've been using EXACTLY what I recommended for 15+ YEARS! Still covert. Install the A/C. Then bring over your neighbors and show them your new little workshop for your new hobby. Hobby = whatever bs you make up! Give it a few weeks or a month or two and then start growing.

    Shed grow uk climate

    I would install a 1-ton mini split, no tent, and run the lights at night to offset the temperature drop. A small space heater would work to raise the temps when the lights are off during the day. INSULATE like crazy and install an AC unit and you're READY TO GO !!!!

    Help with Reservoir

    Yes. I top feed and it drains through the roots/Air Pot and is collected in the flood/drain table where it drains out the bottom to the reservoir. Every 3 hours the pump turns on for 3 minutes and top feeds the plants. Watch YouTube videos on flood and drain hydro. I don't flood the table...

    Cool. I was speaking about cutting the amps in half by using 240v versus 120v.
