Engineered seed-starting mix with bioCHARGE biology for faster germination and stronger transplants
bio365 BIOSTART is a propagation-specific blend of fine peat, coco coir, and perlite built on the same bioCHARGE platform as BIOFLOWER and BIOALL. The fine particle size maximizes seed-to-soil contact for high germination rates, while the dual biochemical buffer gives you a wide margin of error on watering and feeding. Contains a light starter charge of organic nutrients (0.20-0.06-0.26) but is designed for growers who want to control their own feeding program. Made indoors in bio365's controlled-environment facility in Ithaca, NY, FSMA tested, pathogen-free, and ready to use straight from the bag.

Inconsistent texture bag to bag, clumps and dry pockets
No biochar, no engineered biology
Narrow pH tolerance, easy to over or under water
May need rehydrating, sifting, or mixing before use
Often too coarse for small seeds or propagation trays
bio365 BIOSTART
Made 100% indoors in a controlled-environment facility, FSMA tested, pathogen-free
Consistent texture every bag, evenly hydrated, uncompressed
bioCHARGE biology and bioCORE biochar create active microbial life
Dual biochemical buffer gives a wide sweet spot on pH and watering

Fine particle size optimized for seed contact and propagation trays
Features
What BIOSTART does for your seedlings
Engineered for Germination
Fine peat and perlite particle size maximizes seed-to-soil contact. The texture flows evenly through propagation trays, cell inserts, and automated potting equipment including Ellepot machines.
Dual Biochemical Buffer
Two buffering systems work together to keep pH stable and forgive watering mistakes. New growers get a wide margin of error. Experienced growers get consistent, predictable results.
bioCHARGE Biology, Active from Day One
The same bioCORE biochar and microbial inoculant used in BIOFLOWER and BIOALL. Beneficial biology is pre-loaded and active in the bag, colonizing root zones as soon as seeds germinate.
Starter Charge, Not a Full Feed 0.20-0.06-0.26
Light organic nutrition gets seedlings going without risk of burning tender roots. Designed for growers who want to control their own feeding schedule from the start.
ultimateAIR Porosity
Engineered air-filled porosity throughout the mix prevents waterlogging and gives roots the oxygen they need to develop strong, fibrous systems before transplant.
Pathogen-Free, Bag to Bag Consistency
Every batch is made indoors in Ithaca, NY and FSMA tested before shipping. No outdoor composting, no weather exposure, no variability between bags.
Derived From: Pasteurized Poultry Litter, Feather Meal, Dolomite, Bone Meal, Bone Char, Sulfate of Potash
How to use BIOSTART
1
Fill your trays or pots
BIOSTART is ready to use from the bag. Fill cell trays, small pots, or soil blocks. No rehydrating or sifting needed. The fine texture flows evenly into tight spaces.
2
Plant seeds or insert clones
Make a small hole or dibble and place your seed or cutting. Use a seed-starting mix like BIOSTART rather than seeding directly into a hot, fully amended soil, which can burn tender roots.
3
Water lightly and maintain moisture
The dual biochemical buffer makes overwatering harder to do than with standard peat mixes. Keep evenly moist, not saturated. The bioCHARGE biology activates with moisture.
4
Transplant into final medium
Once roots fill the cell or pot, transplant into BIOFLOWER for flowering, BIOALL for veg, or any soil or soilless medium you prefer.

Questions
Frequently asked questions
BIOSTART is designed for propagation: seeds, clones, and early seedling growth. It contains a light starter charge (0.20-0.06-0.26) that will get a seedling going but won't carry a plant through a full grow cycle. Once roots fill the cell or pot, transplant into a full-nutrition medium like BIOFLOWER or BIOALL.
BIOALL has significantly more nutrition (up to 5 weeks) and a coarser texture designed for containers, not propagation trays. BIOSTART has a fine particle size optimized for seed contact, a light nutrient charge that won't burn tender roots, and flows evenly through cell trays and potting machines. If you're starting from seed, BIOSTART is the right choice. If you're potting up a transplant that's already established, BIOALL works.
For the first 1-2 weeks of seedling life, no. The starter charge handles early growth. After that, it depends on how long you plan to keep plants in BIOSTART before transplanting. If you're moving to a final medium within 2-3 weeks, no supplemental feeding is usually needed. For longer propagation holds, begin light feeding with your preferred nutrient program. BIOSTART works with both organic and salt-based nutrients.
Yes. BIOSTART works for clones, cuttings, and tissue culture transplants. The fine texture provides good contact around the stem base, and the light nutrient charge won't overwhelm unrooted cuttings. The bioCHARGE biology helps colonize new root growth as it develops.
Two main differences. First, BIOSTART includes bioCHARGE biology and bioCORE biochar, which means the mix has active beneficial microbes from the moment you plant. Most seed-starting mixes are sterile or near-sterile. Second, bio365 manufactures everything indoors in a controlled facility, so every bag is identical. Outdoor-composted mixes vary batch to batch in texture, moisture, and biological activity.
No. BIOSTART ships uncompressed and evenly hydrated. Open the bag and use it directly. No soaking, no sifting, no mixing required. This is a significant practical advantage over compressed peat or coco blocks that require rehydration and breaking apart.
