Natural and Organic amendments, inputs, fertilizers – Whatever you call them are by far the very best and most healthy way to grow any plant which will soon be eaten, juiced, rubbed on you (salves), smoked or ingested in any way. Considering you are what you eat, your health should be very important to you, eating all naturally and organic should be every Body’s goal.

Our organic fertilizer line is very extensive and mostly OMRI Listed amendments. Sometimes very good all natural products are not OMRI Listed as maintaining an OMRI listing is very expensive and on-going fees yearly. That said, we have some excellent all-natural amendments which don’t carry that listing but are nonetheless great products.

Listed below are all of our products and a brief description of each:

Kelp Meal

Kelp is grown completely submerged and in salt water – do you know of other plants that can do that? Kelp contains serious growth hormones! It has high amounts of iodine, potassium, magnesium, calcium and iron, as well as vitamins, antioxidants, phytonutrients, amino acids, Omega 3 fats, etc. Kelp also contains cytokinins (growth hormones responsible for cell division in plants). Kelp, with all its minerals, trace elements, growth hormones, enzymes, and proteins is beneficial at several stages of a plant’s growth – root development, veg growth and bud set. It can be mixed into soil or used as a foliar spray (early in the morning is best), or a meal mixed into the soil. Both methods used together is by far the best method. Kelp liquid in teas is also very important!

Bat Guanos

We carry two different guano varieties sourced from two different Indonesian and far east locations. Our 8•3•1 guano is a high nitro, fast acting natural source of nitrogen, while also providing phosphorus and potassium in good amounts. Our 0•12•0 guano is a great source of phosphorus , and being fast acting and very finely ground, is an excellent mid-July topdress just before flower and bud time begins. With a texture of baby powder, it is water soluble and can be poured around the root zone before and during flower time. Great for big, hearty buds.

Bat Guano 0•12•055# Bag @ $61.00

Crab Meal/Powder

We have both a powder (fast acting) and a meal (slower release). Both are high in calcium 25% and also magnesium 2.2%. The N-P-K (Nitrogen – Phosphorus – Potassium) is 3.1•2.7•0.3, so it provides moderate amounts of nitrogen and phosphorus, and exceptional amounts of calcium. We use it a lot in our coco based cannabis mixes for the above reasons, and especially the 2.2% of magnesium, which coco based mixes need. It also aids in nematode destruction and prevention.

Crab Meal 3.1•2.7•0.340# Bag @ $49.00
Crab Powder 3.1•2.7•0.340# Bag @ $49.00

Neem Cake

Neem Cake is an excellent slow release (N) Nitrogen which also increases organic matter in the soil and all the while beefing up the plants resistance to many pest and plant maladies.  Neem contains Azadirachtin, which is a natural compound which affects some bugs hormonally. It messes with their egg production, sometimes causes them to “forget” to eat or mate. Think about that – serious mind control. We love Neem as an excellent natural fertilizer and soil conditioner. It creates, nourishes and promotes plant growth and resistance to pests while improving soil quality. Typical N•P•K for Neem is about 4•1•2 but ours sourced from India has an N•P•K of 6•1•2 and an Azadirachtin amount about 1/3 stronger than other good Neem products we have lab tested. It is very high quality Neem. Neem is great for Vegan gardening. It works very well in tandem with other organic amendments such as Crustacean Meals, Kelp, Bone Meals, Guanos and a lot more. We love it.

Neem Oil

Neem Oil, which many people have heard of, is derived from intense squeezing or pressuring of Neem Seed Kernals – think pressing grapes to make wine. The oil drops down to a container and the residue left over is Neem Cake mentioned above. Of the two, Neem Cake and Neem Oil, the oil has the most Azadirachtin thus why the oil is sold in most garden centers. It really is effective in greatly reducing pest populations. Also promising results with mites. Neem Cake and Oil is not a poison! It is in fact used in body lotions, shampoos and toothpaste – Safe for humans! Bugs, not so much.

Our Neem Oil is Cold pressed with no solvents used and nothing extracted from it. Simply cold pressed and put into 55 gallon drums which we import straight from India. Much Neem Oil found in some garden centers has been cut (stuff extracted out of it) one substance extracted from it is used in the rubber industry to create very thin rubber. Ours is uncut and unprocessed cold-pressed Neem Oil. Top shelf stuff!

Fish Bone Meal

Fish Bone Meal is a great source of Phosphorus (root development and fruit, flower and bud development). Ours is OMRI listed organic and thus a great Phosphorus source. Fish Bone Meal is a slower release Phosphorus, so it typically lasts longer in soils than would say a 0•12•0 Bat Guano which is fast acting. Fish Bone N•P•K is 4•17•0. It is also a great source of calcium and trace minerals and nitrogen.

Fish Bone Meal 4•17•050# Bag @ $64.00

Bone Meal

Bone Meal, like Fish Bone Meal, is a great source of Phosphorus in a slow release form. Ours is OMRI listed organic with an N•P•K of 3•15•0. Sourced from Organic slaughter houses (sounds harsh) but if you eat steak, fish or chicken, your dinner probably passed through one of those places. We like Bone Meal a lot as it generally does not have the sodium and salts as does Fish Bone Meal. That said, Fish Bone Meal has some benefits over regular bone meal. It is also an excellent source of calcium and trace minerals. In our mixes we use both in tandem usually.

Bone Meal 3•15•050# Bag @ $64.00

Blood Meal

Blood Meal is a great, strong and fast acting N (Nitrogen) fertilizer. If you have plants in dire need of food this stuff works quickly. Blood meal is a nitrogen source that you do need to be careful with because under the right conditions, it can burn. Used intelligently (which we like to think we are) it is a great fertilizer for fast N coupled with other slower release N sources. Blood Meal ushers in dark rich green foliage and huge vegetative growth. It’s N•P•K in 13•0•0.

Blood Meal 13•0•040# Bag @ $85.00

Feather Meal

Feather Meal is the opposite of Blood Meal in that it is a pretty slow release N (Nitrogen) fertilizer. Feather Meal like Blood Meal are both very high N sources, but Blood Meal is very fast and feather meal is slow. Our feather meal is OMRI listed organic with N•P•K of 12•0•0.

Feather Meal 12•0•040# Bag @ $58.00

Cottonseed Meal

Cottonseed Meal is a more balanced source of N (Nitrogen) and P (Phosphorus) and K (Potassium). It’s N•P•K is 5•2•1 which is a fairly balanced combination. It has not an OMRI listing and is one of the very few fertilizers which has an acidic P.H. and tends to make soils more acidic overtime. In alkaline situations this is good news. Acid lovin’ plants dig it!

Cottonseed Meal 5•2•150# Bag @ $69.00

Alfalfa Meal

Alfalfa Meal is another fairly well balanced mellow fertilizer. It is rich in trace minerals and natural growth stimulants like Triacontanal. The more growth stimulants in the soil, the better off you are. Alfalfa Meal feeds the soil 1-4 months of gradual feeding depending on other conditions in your situation. Further, it really aids in improvement of soil structure, retains water, and propels beneficial soil orgasms – hold on, I mean organisms. It’s N•P•K is 2.3•0.29•2.4. Also, if you are a composter at home, Alfalfa Meal jump starts any compost pile with the right microbes to kick it off fast.

Alfalfa Meal 2.3•0.29•2.440# Bag @ $42.95

Crustacean Meal

Crustacean Meal is an excellent source of N (Nitrogen) in a slow release form with an abundance of trace minerals as well as a good boost of calcium. Crustacean Meal also contains Chitin. Chitin is a main component of the exoskeletons of nematodes, insects, grubs, and some fungi. Why does this matter? When a lot of Chitin is in the soil, it promotes Chitin eating bacteria, which in turn, eat the nematodes, insects, and grubs, etc. that you don’t want, need, or desire. Go Chitin! Remember the Chitins.

Crustacean Meal 4•0•040# Bag @ $59.00


We have 20% vinegar, which has two major uses. It is a great natural way to pH water from any source where the water is above pH 7. If you wish to veg at pH 6.2 and then later flower at pH 6.8, then natural vinegar is an excellent way. Most people water 3-5 times a week so that an ongoing pH regimen with this natural pH adjuster is both inexpensive, natural, and can be done during each watering.

The second use for 20% vinegar is weed control. This product is very acidic, even if diluted 2 to 1, it will burn any plant. Multiple applications over several weeks will kill roots of very tall weeds.

“Hot Stuff”

All of the above amendments we call the “Hot Stuff” in that they provide most of the N•P•K in soils. They provide the Macronutrients all plants need – Those being the N•P•K. Equally important are the Micronutrients which are very important and often forgotten. We don’t forget because your plants are only as strong as their weakest link, and that could be minerals.

Glacial Rock Dust

Glacial Rock Dust (R.D.) is a fairly broad spectrum range of minerals and trace elements which were gathered up in Glaciers in the last Ice Age. Your gardens and flower beds need remineralization every year or so. Lots of folks don’t do it because everybody is always talking about N•P•K. If N•P•K is gyhugic and it is, then mineralization is huge. Glacial Rock Dust helps the soil recreate the colloids (minerals and humas) which are needed to improve nutrient and bacterial availability, moisture holding properties and for sure improve soil structure. When a better balance is achieved, organic matter is more easily converted into humas and the soil becomes a more favorable to earthworms, fungi,and bacteria. Glacial R.D. is also high in silica which is important for cell wall strength (strong stems) while also being a great source of calcium, iron, magnesium and potassium and trace elements and micronutrients. It also aids in CEC (Cation Exchange Capacity). It doesn’t break the bank so use it yearly in container plants, flower beds and gardens. Full PDF available at

Basalt Rock Dust

Basalt R.D. is also made by Gaia Green out of Canada, a top shelf company. It is very similar to Glacial R.D. with some small differences in minerals and their amounts. We like to blend several of these mineral packages for the broad spectrum of mineralization that they provide.

Basalt Rock Dust50# Bag @ $47.00


Azomite differs somewhat from Glacial R.D. and Basalt R.D. in the fact that its origins rather than being mainly glacial from glaciers that traveled in some cases many miles accumulating various different minerals from the surface of mountains as they scraped along. Azomite is more Volcanic in that it came from beneath the surface. We like it in tandem with one or two of the other 4 mineralization products we carry. It seems to improve the CEC as well or better than the glacial R.D. and contains some minerals in larger amounts. As I’ve said, we use a spread of at least three products in our Soiless Mile High Mixes.

Azomite50# Bag @ $47.00

Volcanic Rock Dust

Volcanic R.D. is also volcanic in nature and we secure it from Indonesia. We like ti as its real high in magnesium at over 3% and calcium at 3.3%. When we make Soiless Mixes containing a larger percentages of CoCo Coir, we use lots of it as CoCo in larger amounts requires additional magnesium and calcium.

Volcanic Rock Dust55# Bag @ $52.00


Gypsum is a soft sulfate mineral composed of calcium sulfate dehydrate. Gypsum is a great source of sulfur (which tends to acidify soil) and calcium, which plants require. Gypsum also helps break up heavy clay soils making clay soil more tolerable.

Earth Worm Castings

95-100% Pure Organic Earth Worm Castings:

Worm castings (a.k.a. worm manure, vermicompost, or worm excreta) are rich in plant nutrients, trace minerals and growth enhancers, and incorporating castings into the soil significantly increases microbial life in the root zone. Worm castings are extremely beneficial in that they stimulate plant growth more than any other natural product, enhance the ability of your soil to retain water, and also inhibit root diseases such as root rot. The humus in worm castings removes toxins and harmful fungi and bacteria from the soil. Worm Castings therefore have the ability to fight off plant diseases.​

Slowly release the finest
nutrients into your soil.
earth worm castings for organic fertilizer use

One of the best features of worm castings is you can use as much as you want without the fear of burning tender young plants as other fertilizers could do. Unlike other animal manure and artificial fertilizers it is absorbed very easily and almost instantaneously by plants. The amazing thing is, that while the nutrients are easily available they are at the same time naturally endowed with a slow release feature, causing the nutrient benefits to last up to 2 months! This benefit is put in place during the digestion process of the earthworm. As the organic matter passes through the alimentary canal of the worm, a thin layer of oil coats the material, later eroding over a period of 2 months. The best of both worlds, immediate and long-lasting benefits! Ordinary composts do not have this benefit, they are placed in the garden to enrich the soil and plants, the available nutrients are quickly leached into the soil as soon as rainfall occurs or irrigation systems are turned on. Vermicompost provides a time-released benefit, slowly nurturing the plants over a greater length of time!

Another natural benefit of worm castings is the ability to fix heavy metals in organic waste, which prevents plants from absorbing more of these chemical compounds than they need. The compounds can then be released later when the plants need them. A natural protection for plants set in place by the Creator!

You need only use a small amount in or around your house plants, vegetables and flowers, as the humic acid in worm castings are able to stimulate plant growth, even in low concentrations. Humic acid also stimulates the development of micro flora populations in the soil. The miracles of the earthworm are easily seen in the beautiful growth and yields of your plants. Extremely dark and rich in texture, tests on worm castings have shown the nitrogen content to be 5 times greater than ordinary topsoil, the phosphate 7 times greater, potash 11 times, and magnesium 3 times. Castings will not burn even when applied directly to the most delicate plants. Definitely the finest soil conditioner available. Great for use in your entire garden! Completely odor-free and 100% organic! Use for indoor plants, and container gardening, as well.
