bio365 BIOFLOWER 1.5 cu ft - Happy Hydro

Pre-loaded for flower, built in a controlled-environment facility.

bio365 BIOFLOWER is manufactured 100% indoors in Ithaca, NY using patented bioCHARGE technology. It's compost-free, FSMA-tested batch by batch, and pre-loaded with up to 8 weeks of bioavailable organic nutrients calibrated for the flowering stage.

OMRI Listed CCOF Certified Organic NOFA · NOP · Oregon Tilth FSMA Tested · Pathogen-Free

bio365 is the only soil company whose engineered media has been sent to the International Space Station. In October 2020, a NASA/CASIS-approved Cornell University team selected bio365's BIOALL for the first-ever soil experiment in space. Dr. John Gaunt, bio365's Chief Science Officer and former Cornell adjunct, collaborated with that team. BIOFLOWER runs on the same patented bioCHARGE technology.

How bio365 BIOFLOWER is made and how it works

Why it's different

Conventional soil + bottled nutrients vs. bio365 BIOFLOWER

Conventional Soil + Nutes

Full feeding schedule every watering
Nutrients pushed in regardless of what plant needs
Outdoor composting introduces pathogen and pest risk
Inconsistent batch-to-batch performance
Salt buildup requires flush protocol
Poor air porosity limits root zone oxygen

bio365 BIOFLOWER

Up to 8 weeks of pre-loaded nutrition - significantly reduce or eliminate feeding
Plant signals the biology on-demand - nutrients delivered when and as needed
100% made and stored indoors - FSMA tested, pathogen-free, compost-free
Controlled-environment production - consistent performance bag to bag
Organic inputs - no salt buildup, no flush required
ultimateAIR technology - engineered air-filled porosity throughout

What makes bio365 different: bioCHARGE technology

Think of bioCHARGE like brewing beer. bio365 starts with bioCORE - their patented ultra-pure softwood biochar, produced at high temperature in low-oxygen conditions, with an enormous internal surface area and super low ash content. Then they combine bioCORE with carefully selected beneficial microorganisms and organic nutrient sources, and age the entire batch together indoors under controlled conditions. The result is a pre-activated, biologically alive concentrate that's anchored into the bag before it ever ships.

The key difference from conventional organic soil: the plant signals the microbiology. Rather than flooding the root zone with nutrients on a schedule, the biology in bio365 media responds to what the plant actually requests through root exudates - delivering water, nutrition, and pathogen defense on demand. It works with the plant's natural processes rather than overriding them. The bioCORE biochar matrix provides the permanent structure for this biology to live in and the water-holding capacity to make it work.

What's in it

Built for flower - engineered from the inside out

Up to 8 weeks of pre-loaded, bioavailable organic nutrients Most nutrient-dense bio365 mix

BIOFLOWER contains more nutrition than any other bio365 product - specifically tuned for the elevated phosphorus and potassium demand of the flowering stage, plus silica and key micronutrients often missing from standard mixes. NPK guaranteed analysis: 0.74-1.10-0.50.

bioCORE biochar - softwood only, ultra-pure, multi-patented Extra bioCORE vs. BIOALL

BIOFLOWER contains more bioCORE biochar than BIOALL. The bioCORE matrix holds water in micro-pores and releases it to the plant as needed, raises CEC so nutrients stay in the root zone rather than leaching, and provides permanent habitat for the beneficial biology that drives nutrient delivery.

Compost-free and FSMA tested - indoor production, no pathogen risk

Outdoor composting introduces pathogens, pests, and batch-to-batch inconsistency. bio365 makes everything indoors and FSMA tests each batch before it ships - pathogen-free is tested, not assumed.

Up to 50% water reduction vs. conventional media ultimateAIR porosity

The high-porosity blend of fine coir, coarse peat, and super coarse perlite - combined with bioCORE's water-holding micro-pores - means the root zone stays consistently moist with less frequent watering. The ultimateAIR technology also gives growers flexibility to dry-stress or irrigate frequently depending on their crop-steering strategy.

Works with organic or salt-based feeding programs

BIOFLOWER is designed to carry most plants through flower with no additional inputs - but it's not prescriptive. Growers who prefer to supplement with organic teas or light salt-based programs can do so without disrupting the soil biology. It adapts to how you already work, rather than demanding a complete system change.

Consistent bag to bag - standardized SOPs for commercial grows

Because every variable is controlled indoors, each bag performs the same as the last. Commercial growers use BIOFLOWER specifically because it enables repeatable SOPs across multiple rooms and cycles.

Two ways to use it - standalone or as Part 2 of a two-part system

1

Standalone: fill and plant, start to finish

Fill your container, plant directly, and water. The pre-loaded biology and nutrition carry most plants through the full cycle without a feeding schedule.

2

Two-part system: BIOALL for veg, BIOFLOWER for flower

Start seedlings or clones in BIOALL (up to 5 weeks of veg-tuned nutrition), then transplant into BIOFLOWER at the flip. Each medium is calibrated for its stage.

3

Water consistently - let the biology do the work

The bioCHARGE biology responds to plant signals - deliver nutrients when and as needed, without a feeding schedule. The high-porosity structure suits both frequent irrigation and dry-stress approaches.

4

Supplement if needed - it won't disrupt the biology

BIOFLOWER supports both organic and salt-based feeding programs alongside its pre-loaded nutrition. Running organic inputs means no salt accumulation and no flush protocol needed.

Questions

Frequently asked questions

Do I still need to feed my plants if I'm using BIOFLOWER?

For most plants in a 10-gallon or larger container, no - the pre-loaded nutrition carries through the full flower cycle without supplemental feeding. The "up to 8 weeks" claim is real: the bioCHARGE biology delivers nutrients on demand as the plant needs them, rather than exhausting everything at once. If you're in a smaller container or running a heavy-feeding variety, you can supplement lightly. BIOFLOWER supports both organic and salt-based programs if you choose to add them.

What's the difference between BIOFLOWER and BIOALL?

BIOALL is bio365's all-purpose substrate - up to 5 weeks of nutrition, tuned for vegetative growth and early flower, and the most forgiving of the two. BIOFLOWER is their most nutrient-dense mix, carrying more bioCORE biochar, and specifically calibrated for the elevated phosphorus, potassium, and micronutrient demand of the flowering stage with up to 8 weeks of bioavailable nutrition. Many growers use them together: BIOALL for veg, transplant into BIOFLOWER at the flip.

Why does it matter that it's made 100% indoors?

Outdoor composting - even high-quality compost - exposes raw materials to pathogens, pests, and environmental variability. Every bag of conventionally composted soil is slightly different from the last. bio365's controlled-environment facility in Ithaca, NY operates under near-lab conditions: all materials are brought indoors, the bioCHARGE process is run in controlled batches, and every batch is FSMA tested for pathogens before it ships. You get the same performance from bag to bag, grow to grow.

I heard bio365 sent soil to the International Space Station - what is that about?

In October 2020, bio365's BIOALL became the first commercially engineered soil ever sent to the ISS - approved by NASA and CASIS (the organization managing the ISS U.S. Lab). The experiment was led by Cornell University researcher Morgan Irons alongside Dr. Johannes Lehman, one of the world's leading biochar scientists. bio365's Chief Science Officer, Dr. John Gaunt, is a former Cornell adjunct professor and collaborator with that team. The ISS mission was BIOALL specifically - not BIOFLOWER - but both products are built on the same patented bioCHARGE technology. The research was focused on how biochar-based engineered soils perform in the extreme controlled environment of space.

Can I use BIOFLOWER for a full cycle, or is it only for the flowering stage?

Both. BIOFLOWER works as a standalone full-cycle medium from seedling to harvest - it contains enough nitrogen to support vegetative growth in addition to its elevated P and K for flower. The "optimized for flowering" designation means it's calibrated for plants with peak flower nutrient demand, but it won't hurt plants in veg. Growers who want to use a two-part system (more precise stage-by-stage tuning) start in BIOALL and transplant into BIOFLOWER at the flip.

Does BIOFLOWER work for vegetables, herbs, and other crops - or just flowering plants?

Yes - BIOFLOWER works for any crop with elevated nutrient demand during its productive stage. Tomatoes, peppers, cucumbers, herbs, and fruiting vegetables all benefit from the same high-P, high-K profile that makes BIOFLOWER effective for flowering crops. bio365's media is used in commercial leafy green and culinary herb operations as well. If you're growing something with a lighter nutrient demand, BIOALL may be the better fit - call us and we'll help you decide.
