  1. Hello All,

    I'm Todd, A newbie cannabis cultivator.......

    I Have a 5x5x8 grow tent with a 900w marshydro LED, charcoal filter with inline fan.(albeit, 12x48" Phresh filter-vertical mount. Just need to reduce ventilation ducting from 12-10-6" . Many of the top of the line advanced nutrients. I'm also planning to go FOX FARM soil. I want to use organic mostly. I've heard for feeding a rule of thumbs is once a week. Soil ph as close to 6. A little sketchy on the ppm, any advice there. & I want to use an organic pest control product, I found "green cleaner".

    I intend to even take cuttings for a clone grow, but I'm planning to use a tall portable greenhouse for that. And another for drying & curing. Anything I'm missing? I am also intending to top, and lollipop my plants for more yield.

    I plan on transplanting clones into 3 gallon containers then one more time to 5 gallon containers.


    Would 4 large plants of medium grow height "work" under a 900w mars hydro!(56-60 weeks of flowering and decent yields. )
    Thinking of these strains:


    Sour OG


    Skunk #1

    Any thoughts?!!!!


  2. I would check with Mars to see what the TRUE Wattage Draw is..900w equiv in "Mars Speak" might be 400w true..

  3. That light pulls 364 watts out of the wall and only covers a flower footprint of 3.5 x 3.5. Two plants but not 4 large plants under that light. If you want to maximize your light and yield, I suggest a scrog.
