Frequently Asked Questions:

Q:  When germinating my seeds, can I use the Stonington Blend Grower’s Mix in a solo cup and transplant, or do I need to use the seed starter?

A:      We have heard from growers that they have had success with germination in Stonington Blend, but we really don’t recommend it.  Seeds are very sensitive to nutrients, and germinating them in a nutrient-rich environment can actually cause them damage.  Our seed starter (Sprout Island Blend) was specifically designed for germination and rooting plant cuttings. It has only a mild starter charge from the worm castings, mycorrhizae and kelp, so the seeds won’t get overwhelmed.

 

Q: Do I have to pH my water?

A:      In most cases, no, you don’t have to pH the water. But, it is helpful to know if it is at least in the target range, because the pH level outside of the preferred range can adversely affect how your plants take on nutrients/minerals, and how easily they are made available to the roots. Cannabis likes slightly acidic soil. (preferably 6.0-6.8 – We target Stonington Blend to be a 6.5 pH)  Ideally you would want your water to be in that range too. That way you can confidently know your plant is getting all of the nutrition it needs from our mix.

A more useful way to gauge what is actually going on in the soil is to test the pH of your run-off rather than the pH of the water you put in. The run-off will contain any salts that might be building up in the soil and alert you to possible problems before they occur.

Tip If you are using tapwater, let it sit in a bucket or reservoir for a few days to allow it to dechlorinate, then check the pH to make sure it is within the required range.

 

Q: Is this a “hot soil” for the base of the plant?

A:      No. Because of Coast of Maine’s composting techniques and the way we allow the amendments to settle before we bag the soil, Stonington Blend Grower’s Mix is gentle enough to be right up against the plant.

 

 

Q: Can you ship Stonington to Canada?

A:      At this time we do not ship outside of the US.

    What PH level is best for watering? I see target PH is 6.3. What PH water should be used going in?

      Hi Andrew,

    Great product! What is your best advice when switching over indoor plants to flower? I have heard some growers use the Quoddy Blend Lobster Compost, scratch in two inches into the top and water. When would be the best time to do this and is there anything else I should add for better results?

      • comadmin

      • August 14, 2020

      Hi, we recommend our fishbone meal for that. As for the timing, it would depend on your container size. Follow the feeding schedule on the chart and you should be all set.

    What is your advice when flowering Cannabis? Any additional products that need to be used alongside the Stonington Blend?

      • comadmin

      • August 14, 2020

      Hi, again, it depends on your container size. For an extended flowering stage, we recommend fishbone meal.

          I see in the comment above you say your stonington blend is ph to 6.5 and say ideally you want to water with a ph of around 6.5. What is the best ph down for this organic system if any is needed at all? I use tap water and typically it is between 7.2-7.4 ph. I plan on using coast of maine organic plant food as well as earthworm castings and fish bone meal

    • Ricky Rivera

    Good afternoon. If I can’t find your Stonington Blend but found Bar Harbor potting mix and your lobster compost can I mix those 2 and then your seed starter for Photo and autoflower seedlings

      • comadmin

      • August 24, 2020

      Hi Ricky, While we don’t have a specific recipe for that combination you should be fine. For additional information please send at email to cameronb@coastofmaine.com.

      This is what I was told.”Order these three. Blend the Quoddy and Bar Harbor 50/50 with a tablespoon of the STPF. Top dress with the STPF every 30 days.” (STPF=stonington plant food)

    • September 18, 2020

    Hello,

    I am planning on buying your STONINGTON BLEND Premium Grower’s Mix and using a 25 gallon living soil fabric container for indoor cannabis tent grow. Would I need to increase the amount from your chart to 3/4 cup of Stonington Plant food and 3/4 cup of fish meal if I end up needing to add nutrients? Can this soil also be used as a base for no-till living soil like your organic raised bed mix?

    Thanks!

      • Jimmy

      • September 18, 2020

      Hi again,

      This is Jimmy from the comment above. Can I just plant my cannabis seed directly into my 25 gallon container of STONINGTON BLEND Premium Grower’s Mix?

      Should I water until I get run off with this soil?

        • comadmin

        • September 21, 2020

        Hi Jimmy,
        Technically, you can plant the seed directly into 25 gal pots, but it would be better to start in 1-3 gallon pots and then transplant as the plant grows. (Seeds are very sensitive to nutrients, and germinating them in a nutrient-rich environment can actually cause them damage. Our seed starter, Sprout Island Blend, was specifically designed for germination and rooting plant cuttings. It has only a mild starter charge from the worm castings, mycorrhizae and kelp, so the seeds won’t get overwhelmed. Best if you start your seeds in that, then transplant into the Stonington)

      • comadmin

      • September 21, 2020

      Hi Jimmy,
      Yes. 3/4 cup per feed would be correct.

    • Kathy

    • October 1, 2020

    I have 3 plants I am growing in pro- mix mixed with 1/2 cup of Stonington Blend mix. When 2 weeks are up do I feed it again, it is in veg. Can I over feed them.

      • comadmin

      • October 1, 2020

      HI Kathy, We are assuming you are using Stonington Blend Plant Food, correct? (not Stonington Grower’s mix soil) What size container are you using?

    • Dan

    • October 5, 2020

    Curious about re-ammending soil with your EWC and dry amendments to use for another grow cycle. My desire is to run one bag’s worth in containers, pull root balls after harvest and then re-ammend the soil with Coast of Maine kelp, alfalfa, and lobster meals as well as earth worm castings and compost. Could you provide advice on this? amounts of each amendment to add to one-bags worth of the stonington blend? and how long to allow it to sit and “cook” before planting fresh seedlings? any info would be great!

      • comadmin

      • October 7, 2020

      Hi Dan,
      (assuming these are ~1.5-2cf pots)
      1. Don’t let the soil ever dry all the way out between plantings (decreases your microbial population. Also, it is hard to rewet when it completely dries out)
      2. To each pot, add 4-5 cups of worm castings with 1 cup of Stonington Plant Food (could also sub for a combo of lobster and kelp meal @ ½ cup each)
      3. Mix it well and add a little water if it is really dry. Let it sit for 7-10 days keeping it as moist as you would if a plant was growing in it.
      4. Transplant. (If growing from seed in these pots, cut ½ the fertilizer listed above) Or you can use our Sprout Island Seed starter to germinate your seeds, and transplant the seedlings.

  1. Good product! I have seen a lot of reviews about this one and I am convinced that it is effective. I’ll try to use this one soon and i’ll give a review here. Thank you for sharing.

    • JAKE

    • November 21, 2020

    Hi I’m confused. I’ve read all about your product but in one place it says that this product will feed the plant throught the whole life cycle but then you have the chart lower on the page that gives instructions for adding nurtients. I just don’t want to add too much if I don’t have to. Can you clear this up? I’m in 5gal smart pots

      • comadmin

      • November 23, 2020

      Hi Jake, in a 15gallon pot, Stonington on its own is enough to feed a single cannabis plant through a full grow cycle. When smaller containers are used, there just isn’t enough nutrition available, so supplemental feedings are needed. That is why we provide the feeding schedule/nutrient chart. Hope that makes sense. 🙂
