    Overall I thought this was a great medium during my grow for two kush strains by 00 Seeds.

    I initiating pre charged the medium, made balls for the seeds to germ in, and then made space in the pots. Using a multi feed DTW system I started the first week from 1-4 feeds a day then from there the plants took off eventually being fed 8x a day around 1200 ppm.

    In hindsight I would have used hydroton to top dress because my drip emitters were wetting the sim mix and creating algae but it never got out of hand. I would also use 3 gallon pots next time as I believe 1 gallons were too small, dried out too quickly, and caused problems.
  • First Impressions:
    Felt nice in my hands

    Easy to pre charge

    Makes nice germination balls

    Pest resistant
    Actual Benefits Provided:
    The water reduction was noticeable saving me 10 gallons a week. Several times I set my timer wrong or the power went out and a few days later my pots(1 gallon smart pots) were still hydrated. Root development was insane constantly growing out the sides and bottom of the pots.
    Who should use this product/service?:
    Anyone wanting to preserve water, get away from other hydroponic mediums, go on vacations, or that uses flood and drain.
    User Friendly?:
    Had I not spoken with @coalminer prior to using it I would have made more mistakes. Easier than coco once the set up is done right and preferably hydroton balls used as a top dressing.
    Who should NOT use this product/service?:
    Comparable Products/Services:
    How long have you used this product/service?:
    Four months
  • Positives/Benefits:
    High water retention

    Better root growth


    Easy to charge
    Prone to algae without top dressing

    3 gallon pot or larger - I don't think 1 gallon was large enough
    Able to overcome negatives?:
    I top dressed the pots with dry sim mix but I believe hydroton would have been better.

    I had yellowing leaves in flower and what seemed like calmag or ph issues early on but getting the ph to 6.0 seemed best.

    • High Quality
    Would You Purchase This Product Again?:
    Absolutely if I had to.
    Would you recommend this product/service to another grower?:
    Conclusion/Final Thoughts:
    This is a great inert hydroponic medium with many benefits and no real downsides plus it's infinitely reusable with the addition of enzymes. This will be my exclusive growing medium going forward.

    How hard is it too get roots out for a second run with it? Seems like it went through the medium instead of around it.

      Growpito has bennies to help break down the old roots. My only issue were the roots closet to the stem but I'll be reusing the medium plus the roots in my Malawi grow with the bennies/mega crop.

      For the time being though I have the entire bag of sim mix in a cooler soaking waiting for the next grow
