Does the kit come with a feeding schedule guide?
Yes, general application rates and feeding schedules are contained within the kit. Or found on our website here.

Is this good for any soil? Is a particular soil best?
Bloom City granular fertilizers are fantastic for any type of soil and will help to improve soil quality and plant health over time.  Soilless mixes like Peat and Coco Coir are ideal to grow in as they allow for ideal drainage and root propagation.

What do I use during the vegetative state?
Bloom City "Grow" nutrients should be used on young and growing plants up until flowering. Make sure to use Boost with every watering to help enrich the soil system and maximize the bio-availability of the minerals present in our fertilizer granules.

What do I use during the flowering stage?
Bloom City "Bloom" nutrients should be used on plants that are in the flower stage, make sure to use Boost with every watering to help enrich the soil system.

Do you need to flush out residual nutrients from the soil before harvest and do you feed right up until that time? 
Flushing is not necessary because the high-quality organic materials found in Bloom City granular fertilizers will not leave chemical salts in the soil. Depending on the type of plant grown, feeding for the last week of its lifespan is generally not necessary.

How should I store the fertilizer?
Store in a cool, dry spot, away from light, humidity, and drastic changes in temperature.

Can I use this in a coco coir soil grow? 
Bloom City granular fertilizers can be used in coco coir based media, and will help build organic content which is healthy for all types of plants.

Is this good for auto-flowering? How do I use?

Bloom City products are non-hazardous, non-toxic, and safe around people, pets, and plants. No special handling or transportation is required.

Can these products be used in conjunction with a fish emulsion concentrate without any harmful effects on plant life?
Bloom City granular fertilizers feature ample amounts of sea-based nutrition, including fish and crab. Fish emulsions can be used in small amounts to supplement nitrogen during the vegetative growth stage of plants that grow rapidly and require extra nitrogen.

Does this clog a soaker hose?
Generally speaking, no, but because Bloom City granular fertilizers are not 100% water soluble, it is a good practice to maintain constant turbidity in water and apply immediately after diluting. The recommended application method is top-dressed soils rather than watering in through drip lines.

Where can I find safety data sheets (sds and msds)?
Please download SDS sheets for each product under the "Our Nutrient System" page.

CleanKelp TM // FAQ

What does CleanKelp do?
Bloom City’s CleanKelp formulation contains seven species of wild harvested sea plants that are loaded with vitamins, minerals, and naturally occurring plant growth hormones. CleanKelp improves root and stem growth, relieves heat and drought stress, and combats predators to ensure plants grow vigorously. Simply put, CleanKelp makes plants happy and healthy.  You can add CleanKelp to your everyday watering routine or use it for root dips, foliar sprays, and compost teas. Bloom City’s proprietary extraction methods are gentle and maximize the nutritional benefits of wild sea plants. CleanKelp is rich in naturally occurring enzymes, amino acids, sugars, minerals, growth hormones and macronutrients.

Where does CleanKelp come from?
We are proud to feature the most nutrient-dense kelp in the world, sustainably grown and processed in the Northeastern United States since the 1970s.

How concentrated is it?
Our kelp is rich in trace minerals and amino acids, and provides over 100 compounds that benefit plant and soil health. Scientific analyses have shown that our kelp contains significantly higher amounts of biotin, beta-carotene, and alpha-tocopherol than any other kelp tested.

Why is CleanKelp more clear than other kelp?
To make CleanKelp we developed a set of proprietary extraction techniques, meant to extract only the most critical components of the seaplants. In this process, the highest concentration of nutritional components is extracted and the non-nutritious fiber is left behind (don’t worry, we compost it!). Other kelps that are commonly sold still have all that pulpy fiber left in them - which makes them thick and brownish green, so most of what you buy is actually just filler material.

How often should I water with this kelp? 
For healthy plants, use CleanKelp twice a week at 5-10 mL per gallon of water. For plants suffering from drought, heat stress, salt stress, or pests and disease, use three times a week.

What’s the difference between this and other kelp products?
Most kelp extracts on the market are simply ground up seaweed. Which is….ok.  90% of the seaweed plant is non-nutritious fibrous material, and the real benefit to your plants comes from the organic acids and natural hormones contained within those fibers.  We cut out all that filler and bottle just the best parts of the extract to give you more bang for your buck and more nutrition for your plant. CleanKelp also contains multiple species of specially selected and extracted sea plants, unlike most other kelps which have just one.  What this means is this kelp has an incredibly rich variety of organic acids and natural hormones.

Can CleanKelp be used in hydroponic systems?
Yes, in fact it’s the best kelp on the market for hydro and aquaponic systems. This is due to the high potency and clean filler-free formulation.

Can this be used as a foliar spray?
Yes, CleanKelp is a great addition to your foliar lineup. Once to twice a week at 20-40 ml per gallon is a great way to help plants ease out of stress and keep growing quickly.

Is the kelp used for this product organic?
Yes, each species of sea plant used is organic and grown right in the ocean. CleanKelp is made with only the highest purity sea plants that meet strict quality requirements for mercury, lead, and other heavy metal levels.

Cal-Mag FAQ

What does Cal-Mag do?
Bloom City’s Cal-Mag formulation contains calcium, magnesium, and a wide array of micro-nutrients. Using 100% organic fulvic acid to naturally chelate minerals results in compounds that plants absorb easily and quickly. Cal-Mag improves stalk and leaf growth and prevents common deficiencies. Fully compatible with all growth mediums and can even be applied as a foliar spray for rapid uptake. Add Cal-Mag to every watering for a lush green canopy.

What’s the difference between this and other Cal-Mag products? 
Other brands are often filled with diluted industrial grade chemicals. Bloom City’s approach sources only the highest grade minerals and plant nutrients to ensure the highest bio-availability possible and healthy plant growth. Bloom City Cal-Mag is rich in the widest array of micro-nutrients on the market, including: magnesium, boron, copper, iron, manganese, and zinc. We are the only brand that is fully and organically chelated for superior uptake and bioavailability.

Where is Cal-Mag made?
Bloom City’s products are made in America from the highest quality sources by a small team of passionate plant scientists. All our ingredients are better for plants, better for you, and better for the planet. Bloom City is simply the best choice for the conscientious grower.

Should I use this with coco coir based growth mediums?
Yes, CalMag should be used frequently with coco coir based mediums. Coco coir has a tendency to remove calcium and magnesium from feed water, so using the higher end of the dosing spectrum is best for this medium.

Can Cal-Mag be used in hydroponic systems?
Yes, it was designed to be used in either soil or hydro systems.  The 100% organic acid binding complex helps Bloom City CalMag stay stable and effective in a hydro system.

Does this product contain synthetic chelates like EDTA?  
No, Bloom City’s CalMag does not contain EDTA. We would never use EDTA, it’s horrible stuff.  But check the labels of other brands, you’ll be surprised what they use.  Bloom City’s CalMag contains organic acid chelated micronutrients. This results in better bioavailability and lower toxicity to plants and microorganisms.

Can this be used as a foliar spray?
Yes, the high purity calcium and magnesium sources will quickly correct deficiencies during the vegetative stage of growth. Use at the rate of 5 mL per gallon of water, no more than twice per week.

Silica Boost // FAQ

What does Silica Boost do?
Bloom City’s Silica Boost formulation delivers water-soluble silica directly to the plant’s roots. It improves heat and drought tolerance, increases resistance to environmental and pathogen stressors, and improves water uptake in the root zone. Silica Boost builds strong plant cells and increases growth. Add Silica Boost to every watering to keep plants healthy.

What’s the difference between this and other Silica products? 
Other brands use un-available forms of silica, which will sit locked-up in your root-zone for weeks before roots can breakdown the minerals for uptake. Slow uptake times mean much less effective results. Bloom City’s proprietary 100% organic acid complexed Silica Boost increases bioactivation, which means much faster uptake times and stronger plants.

How long does this silica take to break down?
Silica Boost is already in a bioavailable form and is 100% water-soluble. Unlike other forms of silica, our product is fully available to plants immediately when you apply it.

Can this product be used as a pH Up adjusting formula?
Yes, Silica Boost can be used to adjust the pH of feed water up prior to applying it to plants. Make sure to do a jar test before application to test for any incompatibilities.

Can Silica Boost be used in hydroponic systems?
Yes, it was designed for both soil and hydro systems. It is the only formula available on the market that is 100% water soluble and will remain stable in a hydro system for over a week. Make sure to add it to your reservoir before other fertilizers.

Can I spray this on my plants?
Yes, Silica Boost can be foliar fed at the rate of 5 mL per gallon of water, no more than twice a week.

Can I use this with other nutrients?
Yes, Silica Boost can be used with most other nutrients, it is best applied to feed water before adding other nutrients. If you are unsure of compatibility, you can feed silica with plain water during a watering when you are not adding other nutrients.

Where is it made?
Bloom City Silica Boost is made in America by a small team of passionate plant scientists and uses a 100% organic acid to increase bio-availability.
