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 10; slowly top-watered about a quart each with a sprayer, around the outer rim:

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…

Day 29…didn’t get a chance to tend to these guys for a while due to family things but they were still alive, and a little thirsty with the SH looking the roughest of the three. I topped off the water reservoirs last night and raised the light a few clicks:


Trying to keep the plants small this grow so I did some significant pruning of the lower stuff touching the soil, as well as ~4 large fan leaves each that blocked a lot of flowering sites, and the bottom 2 branches of the LMZ.
After which I added enough new soil to help stabilize trunks, and top-watered in with the sprayer a pint or two of water each with some molasses to get the new topsoil involved:

Thanks! Hoping to keep them small this time to figure out a way to get 4 to healthily fit in my environment for future cycles (for strain variety).

Reminds me of the quote: “Bravery is not the absence of fear. Bravery is feeling the fear, the doubt, the insecurity, and deciding that something else is more important.”

Last grow, I had to supercrop the main cola on one in the middle, at 53 days above ground, when it was 40”+ from the soil and creeping on the light. Moving things around in the tent didn’t make sense due to airflow/humidity concerns, but

You can see that it didn’t hurt too much, from this picture a couple weeks after:

Day 31, adjusted the light for height and increased the dimmer so they should be getting ~750 PPFD/49 DLI max and ~650/42 average:
