Indoor Autos in Organic Soil with Tap Water

Growing a few of my oldest seeds:

  • (CC) Humboldt Seed Company’s Caramel Cream F2 feminized autoflower
  • (LMZ) Dessert Seeds’ Lemonz feminized autoflower
  • (SH) Dessert Seeds’ Sour Headz feminized autoflower

Used the paper towel method, two germinated in <24hrs (the third will likely be one more day) and then:

  • Roots Organics Lush soil

  • 3 x 5 gallon food-safe buckets with GroBucket inserts

  • 7w 254gph aerator pump (to keep the water reservoirs from stagnating, and the roots seem to love it).

  • Tap water as needed (that doesn’t appear to have chromium, based on local water quality reports), but aired-out ~24-48hrs for chlorine reasons, and roughly PH’d to the mid 6s based on the periodic testing color/using GH drops.

  • 2’x4’x6’ tent

  • 4 inch inline extraction fan and carbon filter, 6” clip fan, and 6” oscillating fan (all off to start, to help with environment)

  • 300w LED: 24/7, ~25%, ~20” from the soil to start, until there are leaves and the humidity domes come off (then 18/6 and % as appropriate):

The CC, LMZ, and SH have been above soil for 1 day now. Domes come off, light going to 18/6, ~25%, ~20” from the seedlings. Temp/RH are ~mid 70sF/% :pop::

Day 3 and folks are a little leggy, so I moved the light a few clicks up to keep it ~20” from the seedlings, and increased the dimmer to ~38%, so the middle should be getting ~400 PPFD/25 DLI. I also have the upper fan at ~20% and the extraction fan on ~10-20%, 24/7 now :popcorn:

SIPs are a game changer for successfully watering soil grows sufficiently, and with a lot less effort :blush:

Day 14, top-watered 1 gallon between the three with 1 tblsp of unsulphured Molasses mixed in for the soil microbes; and adjusted the light so the middle guy should be getting ~620 ppfd/ ~40 DLI…
