    Happy to announce my 2nd grow journal, for this run of:

    "Barney's Farm" LSD auto
    LSDauto-1.jpg LSDauto-2.jpg
    This will be my 2nd indoor growing attempt with autoflowers. My first grow can be found here:

    - 2x4x6 grow tent
    - HLG Elite 360 LED fixture (2 x QB96 V2 boards)
    - 6" AC Infinity exhaust fan w/ carbon filter

    I'll also be using an 24" Sunblaster LED and an 24" Sunblaster T5HO, both 6400K, for supplemental lighting during early veg stage.

    I'll be using a very similar soil mixture to my last run, with a few small changes...
    Fox Farms Ocean Forest - 50%
    Black Gold Container Mix - 40%
    Perlite - 5%
    Permier manure compost - 3-5%
    Vermiculite - 3%
    Gaia Green 4-4-4 dry amendment fertilizer - 1 tbsp/gallon of soil
    Gaia Green 2-8-4 dry amendment fertilizer - 1 tbsp/gallon of soil
    Myke Herb & Vegetable mycorrhizae - 2-3 tbsp/gallon of soil

  4. Each QB96 board is rated to 180 max watts, hence the name of the fixture: "Elite 360"

    I have 2 probes for monitoring environment, my Cloudline T6's probe stays close to the canopy of the plants, my other probe sits 1-2ft above my light fixture during veg but once i start cranking up the lights i move the probe close to my driver.

  12. No worries dude, ya those boards are fantastic and can really pump!
    I'm currently looking at supplementary lighting options so i can run them a bit lower and to try to even out the PPFD across the whole 2x4 space.

    I'm looking at the HLG Saber 100, QB288 V2 Rspec, Atreum Ara-40, or even a couple more QB96's...

  16. "LSD auto" week 2:

    Day 8:
    - no water
    - Temp: 74-80F
    - RH: 68-71%

    Day 9:
    Outside temperatures have dropped a little bit. My outside air intake is controlled by the negative pressure my exhaust fan creates. Last night the tent went down to 72F so i turned my exhaust fan all the way down until later in the morning, reducing the cold air coming in.

    I'm working on a way that i can better manually balance the amount of cold, outside air that's being drawn into the tent, with the warmer air of the room itself.
    Currently, i stuff a small cotton-filled pillow into whichever intake duct i don't want to use.
    I've got the one 4" intake from outside and one 4" intake connected to my portable air conditioner. If the air conditioner isn't on (which it won't be until later in veg/flower), it will just draw air from the room itself.
    I've got these wild dreams of a thermostat, connected to a motorized valve/damper... mmmm...automation! :ey:

    - watered lightly
    - Temp: 72-79F
    - RH: 64-69%

    Day 10:
    - Lightly watered
    - assigned ID to each plant, based on robustness of each plant throughout germination and first week as a seedling.

    - Temp: 72-80F
    - RH: 64-68%

    Day 11:

    My girl has orchids growing in our front hallway. We discovered that one of them has a major fungus gnat affliction. We immediately quarantined it and i've been laying sticky traps all over the house.

    I figured the tent was safe since it's in a different area of the house but i threw down some sticky traps anyways.
    In 24hrs there were 2 of the little bastards that got stuck.

    We use BTI (Bacillus thuringiensis israelensis) to treat the orchids... Should be safe for use on cannabis too, right?
    I'll do a bit more research before i apply it but the reason my girl likes it for the orchids is that it's non-toxic.

    - Temp: 69-76F
    - RH: 62-67%
    - No water

  18. BT won't help the gnat thing. Maybe Cucumeris will help. Can get them from Niagra falls for $1.50 a pack.
    *neem oil spray and drench can help.
  19. I'm not familiar with Cucumeris, i'll have to look into it.
    I'm pretty sure it's BTI that my girl uses for the orchids, which usually works pretty well for her, although i'm not sure exactly how to apply it, how often and the necessary duration.

    I went to a couple of local shops yesterday to look for neem oil but so far haven't had any luck tracking it down.
    Amazon is always a last resort for me... i always prefer to support my local, independently owned shops.

    Luckily, the problem doesn't appear to be too bad right now, but i know how quickly things can get out of control.
