Vital Garden Supply and Bloom
Vital Garden Supply builds living-soil programs: compost, tea, inoculants and organic feeds. Bloom brings liquid tonics and stage timing. Some bottles share a job. Here’s the full line-up.

Living soil from Vital, stage timing from Bloom.
Vital’s chart is simple on purpose: a veg feed, a bloom feed, Cal-Mag and humus, 1–2 times a week, with kelp and compost tea in the advanced version. What it doesn’t have is a week-by-week stage plan. Bloom’s Pre, Ultra, Phat, Ooze and Final are built for exactly that, and they sit on top of a soil program that already runs.
- Stays as is: Vitality soils, compost, Vital Tea, Vital Plus, mycorrhizae and Vital Defender.
- Both have one: cal-mag, humus and humic, kelp, and fish. Run one, or test them side by side.
- Not on their list: stage additives, sea minerals, a carbohydrate input, PK and silica.

Timing from Vital’s simple and advanced feeding charts, which split the grow into vegetative and bloom and fruiting. Vital Veg carries into the first 2 weeks of bloom, so it’s pale at the flip. Vital Tea’s page says weekly in veg and 1–2 weeks into flower. Humus can go on up to a day before harvest. Their chart doesn’t mention a flush, so other bars stop at week 6 (our read). Bloom’s bars follow its weekly feed charts; pale Bloom bars are as-needed bottles.
Why each one fits
What the Bloom product does, the research behind that kind of input, and where it sits in a program that already runs.
A bottle for each part of flower
What it does. Ultra at the flip (flower weeks 1–2, 1 ml/L), Phat in weeks 3 and 4 (2.5 ml/L), Ooze from week 5 through the flush (2.5 ml/L), and Final for the last two weeks alongside Ooze (1 ml/L). All weekly. These are timing tools, so there’s no study cited for them here.
How it stacks. Vital’s chart runs Vital Bloom 1–2 times a week through bloom with no week split. Bloom’s stage bottles drop into those same weeks without changing the base (our read: watch runoff when you add anything).
Carbs and sea minerals
What it does. SWTNR brings carbohydrates and potassium at 1 ml/L weekly, veg week 2 to the flush. Sea Minerals is trace minerals from sea water at 0.13 ml/L weekly, veg to bloom. Feed tools, so no study cited.
How it stacks. Vital’s range leans on compost, humus and teas for the soil side. SWTNR and Sea Minerals are small liquid doses that ride along in the same weekly water (our read).
Two kelps, two jobs
What it does. Seaweed is southern bull kelp at 1 ml/L weekly, seedling through the flush.
A 2021 review of seaweed extracts reports effects on root growth, nutrient uptake, flowering and stress tolerance across many crops. It doesn’t compare kelp species or test either company’s product.
How it stacks. Vital Kelp is a dry Ascophyllum powder used 1×/week and in their foliar mix. Bloom’s Seaweed is a liquid bull kelp. A grower could run one in the drench and keep Vital’s in the foliar, or test one against the other (our read).
Their line, Bloom’s fit at a glance
Matched on job, not NPK. Vital prints rates per US gallon, 1–2 times a week; Bloom prints ml per litre on a weekly feed chart. Tap a tag to filter.
Keep the organic feed. Bloom’s additives go in alongside it.
Media is Vital’s space. Bloom works in soil, coco and hydro.
Soil biology stays on Vital’s schedule.
A fungal inoculant at planting. Bloom’s Roots is a liquid feed additive, a different job.
Both are crop protection with different labels. Follow each label; no feed overlap.
Both are calcium and magnesium. Vital’s carries soy protein; Bloom’s lists iron and zinc. Pick one.
Both put humic material in the root zone. Vital’s is peat humus; Humate is 10% humic acid.
Both are kelp. Vital’s is a dry Atlantic kelp; Bloom’s is liquid southern bull kelp.
Both bring a fish input. Seafuel is tuna and kelp, run weekly.
One additive for mid veg, one for the flip, one for the last two weeks.
Phat in flower weeks 3 and 4; Ooze from week 5 right through the flush, alongside Final.
Carbohydrates and potassium from veg week 2; trace minerals from sea water.
Silica added first in veg; PK an as-needed bottle around flower week 5.
Put it side by side
Where both ranges have a product for the same job, the fair answer is a test in your own room. Here’s what to watch and how to keep it fair.
Keeping it fair
- Same plants. Clones off the same mother, same cultivar, same age.
- Same room. Same light, climate, media, pot size and watering.
- Same base. Keep the base feed and EC the same on both sides.
- One change. Change only the product being tested, and write down what you see each week.
Where the programs complement each other
Vital’s soil, Bloom’s stage plan
Vital’s chart is veg and bloom, 1–2 times a week. Pre, Ultra, Phat, Ooze and Final add a week-by-week plan on top of it at 1–2.5 ml/L weekly.
Cal-Mag, humus, kelp and fish
Four jobs where both ranges have a bottle. Fair tests in a grower’s room show which one stays, or whether both earn a spot (our read).
Silica, PK and SWTNR
Vital has no silica, liquid PK or carbohydrate input on its list. These three slot in without touching their feed, teas or media.
Already covered
- Organic feed. Vital Veg, Vital Bloom and dry options like Bat Guano and Bloom Powder.
- Calcium and humus. Vital Cal-Mag and Baseline Liquid Humus.
- Soil biology. Vital Tea, Vital Plus, mycorrhizae, compost and soils.
- Pest control. Vital Defender.
Stays exactly as is
- Soils, compost and media. Bloom has no growing media.
- Teas and inoculants. Bloom has no microbial product.
- Vital Veg and Vital Bloom. Bloom’s additives go in around them.
- Cal-Mag, humus, kelp and fish. If they’re working, keep them, or test Bloom’s next to them.
Background, science and sources

What each company brings
Vital Garden Supply: Organic liquid and dry feeds, cal-mag, liquid humus, kelp and fish, compost tea, inoculants, mycorrhizae, a plant-based pest control, soils and bulk media, and a simple two-stage feeding chart.
Bloom: one additive for each stage of the crop, seaweed, humic and sea mineral inputs, foliar sprays, and weekly feed charts for soil, coco and hydro. Rates and timing are on every product page.
Cropping Solutions, the other brand under Agricultural Organics, isn’t part of this report.
Dose basis: how each side counts
Vital prints rates per US gallon, mostly 1–2 times a week. At 3.785 L to the gallon, Vital Cal-Mag’s 10 ml/gal is about 2.6 ml/L, Baseline’s 5–15 ml/gal is about 1.3–4 ml/L, and Vital Kelp’s 5 ml/gal is about 1.3 ml/L. Bloom’s Cal-Mag and Seaweed are 1 ml/L, Humate 2.5 ml/L, all weekly.
Vital’s rates can run twice a week; Bloom’s sit on a weekly chart, so the same number on each side isn’t the same weekly amount. The analyses differ too.
Mix calculator
Rates as printed on each company’s page (1 US gallon is 3.785 L). Bloom’s rates are per litre of nutrient solution, dosed weekly per its feed charts. Pick a product and your tank size.
Humic substances and rootsWell supported
Canellas and colleagues (2015) review humic and fulvic acids in horticulture and link them to changes in root structure, including more lateral roots, and to nutrient uptake.
Why it matters here: Baseline Liquid Humus and Bloom’s Humate both bring humic material to the root zone. The review doesn’t test either product.
Fish and other protein hydrolysatesEmerging
Malécange and colleagues (2023) review protein hydrolysates as biostimulants, including their links to nitrogen and mineral uptake. Much of the work is recent and mostly under stress conditions.
Why it matters here: Vital’s fish products and Bloom’s Seafuel are both in this group. The review doesn’t test either one.
