    What you think about mixing a bunch of ~1x1x1" or smaller chunks of Rockwood mixed in with a soil? (Like at 2:53, but mixed maybe 1:4 rockwool to soil)

    When you get a larger plant, cut off a clone, cut the bottom tip at a angle, then just poke it right into the top, just let you did with your water squirter… never having to transplant. 6x6x4 is prefect size

    Do anyone know the the Rockwool to Pot equivalent rate on the Gro-Blocks? what I mean by that is if using a 2×2 Grow Block is that the same as having the plant in a 1gal Pot & that big block thats in the video, believe I heard him say a plant can go from seed to harvest in a Big Block if thats the case what is that Big Block equivalent to in POT GALLONS as far as Root Growth? Hope thats makes sense & Thanks for any & all Help

  24. Properganda Live on June 12, 2022 at 6:37 pm

    Rockwool is shit and is bad for the environment..



  25. Torrie Landsman on June 12, 2022 at 6:39 pm

    You should not have your drip line discharging directly on the trunk of your plant, but good info otherwise.
