As a manufacturer of fertilizer, it is sometimes necessary that we address its application on unconventional as well as conventional crops. With the spread of legalization of marijuana for recreational use across the U.S. and the decriminalization of possession of small amounts of plants for personal use, it would be interesting for those backyard and tabletop pot farmers to understand the benefits of using Fish Fertilizer Concentrate and Seaweed & Fish SoilTabs to aid in growing large healthy plants.
Since most recreational farmers are growing for their own use, they would want to produce plants that are free of chemicals, resistant to blight (mold, mildew) and are strong enough to resist high summer temperatures, over-watering, under-watering, bending from the wind, and attack by insects. Most people do their growing in small ceramic or plastic pots or in discreet garden areas. This article is written for you.
Step 1 (before planting): Find the best potting soil available. Typically this can be something like formula 404 or 707. These are organic mixtures that incorporate some peat moss, a little sand, some guano/manure and dirt. To this, add approx. 5-10% Fish Fertilizer Concentrate by volume and thoroughly mix into the soil. This will allow the bacteria in the soil to immediately go to work on breaking down and converting the fish into its individual nutrients to feed your plant.
Step 2 (add seedling): If you have a seedling or a clone with decent root growth, insert the plant into this soil mix, careful not to damage the roots. The container you use should have some small drain holes at the bottom to prevent over-watering and rotting of the roots. Remember that these are weeds and do not require a lot of water.
This initial fertilizing should be sufficient for the first 4-6 weeks of growth. If your container is clear plastic, you likely will see the appearance of many roots growing around the plastic looking for more space. This is a good sign for you to either transplant them into the ground if you are fortunate to have an outside yard. If no yard is available, move them into larger clay pots.
Step 3 (transplanting): Whether you are transplanting into larger pots or directly into the soil, this is now the next opportunity to add more fish to a fresh soil mixture and blend, before carefully inserting the young plant. Marijuana plants are notorious for consuming all the nutrients in the soils. Therefore, having another opportunity to add new fertilizer to the plants is important after 4-6 weeks and at the time of transplanting. You do not need to worry about burning the roots as you might from using commercial chemical-based plant fertilizers or their more convenient plant sticks. Lightly water to allow the fish to begin decomposition.
With good sunlight, not too much water, and in good soil and fertilizer, these small plants should rapidly grow during their vegetative state into large bushy specimens shown below.
Step 4 (Flowering stage): By mid-September, when the amount of sunlight begins to diminish below 12 hours/day, these plants will enter into their final phase called the “flowering” stage. This is the point where they have reached their maximum growth and now devote their energy to producing their buds (also known as flowers). They therefore do not need the high nitrogen content found in the Fish Fertilizer Concentrate. But they do need the high phosphorus and potash found in the seaweed that is available in the Seaweed & Fish SoilTabs. This fertilizer comes in tablet form and can be pressed into the ground around the root structure of these mature plants without damaging their roots. 
This will take you though the final 4-6 weeks, depending upon your location, until the buds (seeds) are ready for harvest.
Please note that Seagate does not operate a marijuana farm … though that might be a lot more lucrative than growing our broccoli and tomatoes. We neither promote nor discourage anyone’s personal choice for using pot or seeking the benefits of medical marijuana. We do however grow hundreds of acres of vegetables, fruits, and trees using our fish and seaweed as the only source of fertilizer. Therefore, we are a very good resource for you for unconventional farming methods.
Seagate has written extensively on the use of our Fish Fertilizer in your garden. For more information, consider reading several of these articles:

What about the mercury content in fish fertilizer?
Karen – It is negligible. We do not begin to detect levels of heavy metals (mercury,lead arsenic) until we move higher up on the food chain to species such as shark, tuna, swordfish etc. The fish we use for fertilizer are sardines and or anchovies.
I’m interested in growing my own personal medicine. And I’m looking for a super compost tea or fish fertilizer for my Super Soil called Budmud. I want to keep it a simple organic non chemical grow. I’ve got kelpman fertilizer and molasses right now but I feel it’s missing something extra in the super soil. Any information would be greatly appreciated.
Hi Ricky,
What you might do is instead of using the soil-tabs mentioned in this article, since you already have the kelp, I would get the 100% fish fertilizer concentrate. I would pour some either directly into the hole, if you are planting directly into your garden, place the plant on top of it and fill the rest of the space in with a really good soil. If you are using clay pots, do the same thing but at a reduced amount. This product is just ground up and dried sardines. This is a very effective fertilizer. Since it is natural, it will not burn the roots.
Are you able to use fish food when you water to give it nutrients?
Jetter,
We make fertilizer from whole fish that we use on our farm. But it is not fish food. It is fish fertilizer.
Thank you

Cannabis stores heavy metals within its root system and sugar leaves.
Any plant that is exposed to heavy metals, chemicals, or any other contaminants in the soil would absorb and store such contaminants in the structure of the plant.
The trick is not to add anything like that to the soil or to begin growing with soil having a residual level of heavy metal contamination.
If the heavy metals are not present in the soil, water or fertilizer, the plant is not going to manufacture these chemicals and store them.
I keep finding mold on the top of my soil. The only new thing I’ve done is used fish meal
Hello Kendall,
There are many things that can cause mold on top of the soil. One of them is not fish fertilizer.
In order to understand this a little more, here is a question for you –
Since you are growing during the current months, can we assume that this is indoors?
Thank you
Very helpful and useful information here. Thank you
Thankyou this was Wonderful!!!!!
Hi Richard,
I recently purchased the fish and kelp concentrate. I wanted to introduce this to my plants, how often do you recommend in the beginning and how often do you recommend watering outdoor plants? I’m in Southern California. Thanks
Hello Dennys,
Depends upon the size of the plant and its needs for food for the calculation of how much fertilizer to add. However, I would stick to approx. 12 tablets placed into the dirt around the roots. More (24) would not be a problem since this is a natural fertilizer that will not cause root-burn. One application should usually be enough for entire the vegetative phase as it will release slowly and be broken down in stages by the bacteria in the soil.
Regarding watering — Keep in mind that we are only a fertilizer manufacturer, but are not experts for giving advice on how to grow pot plants. Also, Southern California has a lot of different climate zones – coastal (lots of clouds and humidity), inland (hotter and dryer with more sunlight throughout the day), mountains and desert which have very dry air and very dry high winds during the summer. Seagate operates our own (vegetable and fruit, not pot) farms which give us some experience on growing things outdoors in these types of climates. Some vegetables we find better suited to growing closer to the coast. Others (nopal, carrots, olives) do fine inland. So there is no fixed answer on how often you water outdoor plants other than to say that you water them when they need watering. If it is hot and dry or you are having Santa Ana winds, you need to check daily on the dryness of the soil and the plants and see if you need an extra watering on certain days or longer waterings to keep the plants from drying out. If it has been cool and cloudy, too much water can cause root rot and kill the plants. This is something you need to observe on a daily basis in farming. You might want to spend some time reviewing YouTube videosYouTube videos that go over these concepts for beginners.
Thank you

Hi Richard (founder)
I use fish fertilizer now and want to boost my asiatuc lilies and tomatoes. What will promote bloom and fruit growth?
Asiatic Lillies*
If you are already using the fish fertilizer, then that would have been my recommendation. We use this all by itself to fertilize on our commercial farm for all of our fruits and vegetables. I also use it in my home garden for our vegetables, trees, and roses. It helps the bloom and the growth. I personally do not use anything else.
Regards,
Richard
i use it a a special fish sauce when cooking my home caught trout.
Hi Geoffrey,
I really hope that our are joking. The fish fertilizer is FERTILIZAR BECAUSE IT IS NOT FOR HUMAN CONSUMPTION. We have been producing this product for over 20 years and you are the first person we have ever from that is actually eating it. Unless you are trying to kill yourself on purpose … I strongly recommend that you stop eating it.
Thank you
