Why Choose Microbe Life Photosynthesis Plus

Photosynthesis Plus is designed to address a specific gap that many growers encounter: establishing and sustaining a productive microbial population in growing media that starts with little or no biology — such as rockwool, coco coir, or cleaned-out recirculating systems. Here is what sets it apart from generic microbial inoculants:

• Dual-zone action. The microorganism consortium in Photosynthesis Plus is formulated to be active at both the root zone and the leaf surface (foliar level). Most biological additives focus exclusively on the rhizosphere. The foliar component means the product can support the plant’s photosynthetic machinery directly, not just via nutrient uptake at the roots.
• Stable microorganisms. The cultures in Photosynthesis Plus are described by the manufacturer as stable, meaning they maintain viability through normal storage and handling conditions — an important practical consideration when using liquid microbial products in a commercial or semi-commercial grow environment.
• Effective in media void of organisms. Because Photosynthesis Plus rapidly establishes essential plant-supporting biology even when starting from a biologically clean medium, it is particularly useful in systems where growers deliberately avoid uncontrolled microbial populations (e.g., deep water culture, NFT, aeroponics).
• Supports CO2 conversion. The core mechanism described by Microbe Life Hydroponics is improving plant conversion of carbon dioxide into available carbon to fuel plant requirements. This is distinct from typical microbial supplements that focus on nitrogen fixation or phosphorus solubilization alone.
• Broad compatibility with nutrient programs. Photosynthesis Plus is positioned as an additive that works alongside existing base nutrient regimens. It does not replace a full nutrient program but is intended to optimize the plant’s ability to use what is already present in the feeding solution.

Best Uses for Microbe Life Photosynthesis Plus

Photosynthesis Plus is categorized under Growth & Bloom Boosters in the Nutrients & Additives section. Based on the manufacturer’s description, the following scenarios represent its most practical applications:

• Hydroponic systems starting from clean media. When setting up a new reservoir or beginning a fresh run in rockwool, clay pebbles, or another inert substrate, Photosynthesis Plus introduces a functional microbial community from the first watering rather than waiting for beneficial organisms to establish naturally.
• Recirculating systems (DWC, NFT, RDWC). In recirculating setups where the nutrient solution is regularly replaced or sterile conditions are partially maintained, a stable microbial supplement like Photosynthesis Plus can support plant biology without introducing pathogens or unstable cultures.
• Foliar feeding programs. Because Photosynthesis Plus is formulated for foliar application as well as root-zone use, it fits naturally into spray programs during vegetative growth when rapid canopy establishment is a priority.
• Soil and coco coir grows. In organic or semi-organic growing programs, Photosynthesis Plus can be added to the root zone to accelerate microbial activity and support the plant’s own biological processes alongside organic inputs such as molasses or kelp. Growers using Earth Juice Hi-Brix Molasses as a carbohydrate feed often layer in a microbial activator like Photosynthesis Plus to support colony development.
• Recovery and vigor restoration. When plants show signs of stress — slow growth, pale coloration, sluggish response to nutrient adjustments — adding Photosynthesis Plus to the irrigation schedule can help re-establish healthy root-zone biology and restore normal metabolic function.
• Early-stage seedling and clone establishment. Introducing beneficial microorganisms at transplant or during early root development can reduce transplant shock and promote faster establishment in the new growing medium.

Microbe Life Photosynthesis Plus vs Similar Products

Photosynthesis Plus occupies the biological supplement segment of the additives market, sharing shelf space with a range of microbial inoculants and biological activators. Here is how it compares at a general level to the category:

Photosynthesis Plus vs mycorrhizal inoculants. Products like Advanced Nutrients Tarantula deliver mycorrhizal fungi and beneficial bacteria focused primarily on root colonization and phosphorus availability. Photosynthesis Plus takes a different approach: its stated mechanism is the improvement of CO2-to-carbon conversion and support for the plant’s own photosynthetic machinery, and it applies this at both the root zone and the foliar level. The two product types are not direct substitutes and are often used in combination within the same nutrient schedule.

Photosynthesis Plus vs carbohydrate supplements. Carbohydrate additives (such as molasses-based supplements) feed existing microbial populations but do not themselves introduce microorganisms. Photosynthesis Plus introduces a stable microbial consortium directly, making it the more appropriate choice when the growing medium starts biologically empty or when building a specific population from scratch. Carbohydrate supplements serve as complementary inputs once an active microbial community is in place.

Size and cost considerations. At the 1 Quart (32 fl oz) size, Photosynthesis Plus is suitable for small-to-medium grow operations and growers who want to evaluate the product before committing to a larger container. Microbe Life Hydroponics also offers larger sizes (1 gallon and above) for commercial-scale use where per-gallon cost becomes a more significant factor.

Compatibility

Photosynthesis Plus is designed as a broad-spectrum microbial additive compatible with the main growing methods used in controlled-environment agriculture:

• Growing media: Inert substrates (rockwool, clay pebbles, perlite, coco coir), soil-based mixes, and hybrid media blends. The manufacturer specifically notes its effectiveness in media void of organisms, indicating it is intended for sterile or near-sterile substrates.
• System types: Compatible with drain-to-waste and recirculating hydroponic systems, including deep water culture, nutrient film technique, ebb and flow, and drip irrigation. Also suitable for hand-watered soil and coco coir programs.
• Foliar spray compatibility: Can be used as a foliar spray during vegetative and early flowering stages. When using as a foliar application, apply during lights-out or in low-light conditions to minimize evaporation and potential leaf stress from wet foliage under intense lighting.
• Nutrient line compatibility: Photosynthesis Plus is positioned as an additive supplement compatible with most hydroponic nutrient programs. It does not contain NPK salts that would significantly alter EC readings when used at normal additive doses. Growers running root-zone conditioning products alongside biological supplements should monitor overall EC and adjust base nutrient quantities accordingly.
• Organic and conventional programs: The microbial nature of the product makes it a natural fit for organic or biological growing programs, but it is not incompatible with conventional synthetic nutrient schedules provided strong oxidizing agents (high-dose hydrogen peroxide treatments) are not applied simultaneously.

Usage Guidelines

Photosynthesis Plus is a liquid concentrate applied as a root drench or foliar spray. The following guidelines are derived from the manufacturer’s category documentation for biological nutrient supplements and the product description. Always consult the current Microbe Life Hydroponics label for exact dose rates, as formulation updates may change recommended amounts.

1. Shake the bottle thoroughly before each use. Liquid microbial products can settle during storage; agitating the concentrate ensures an even distribution of organisms in the measured dose.
2. Measure the recommended dose using a calibrated syringe or measuring cup. For additive-tier biological supplements in this category, typical starting rates are 2–5 mL per gallon of water for root applications and 1–2 mL per gallon for foliar sprays — refer to the current product label for Microbe Life’s specific recommendations for Photosynthesis Plus.
3. Mix into pH-adjusted water first. Prepare your irrigation or spray solution by adjusting base water to the appropriate pH for your growing method (typically 5.8–6.2 for hydroponic systems; 6.0–6.8 for soil). Add Photosynthesis Plus after pH adjustment and stir or shake gently.
4. Apply at regular intervals. Biological supplements are most effective when applied consistently throughout the grow cycle rather than as one-time treatments. Incorporate Photosynthesis Plus into every watering or on a weekly schedule depending on your system and feeding frequency.
5. Do not combine with strong oxidizing agents. Avoid applying Photosynthesis Plus in the same solution as high-concentration hydrogen peroxide, chlorine-based sanitizers, or other oxidizing additives, as these will kill the live microorganism cultures.
6. Store in a cool, dark location. Keep the bottle out of direct sunlight and away from temperature extremes. Refrigeration is not required but storing in a stable, cool environment extends shelf life of the live cultures.
