Optic Foliar

Optic Foliar Transport

Optic Foliar Transport is a premium foliar spreader, penetrant, and uptake enhancer engineered to maximise the efficiency and impact of foliar-applied products. Its innovative formula allows growers to spray safely with lights on or in full sun without the risk of burning, bleaching, or leaving unwanted residues. Unlike conventional foliar sprays that require underside application, Transport’s advanced surfactant technology evenly coats and penetrates both sides of the leaf, reaching the mesophyll layer for rapid nutrient or treatment absorption. By enhancing the movement of active ingredients directly into plant tissue, Transport accelerates visible plant responses, optimises the performance of foliar feeds, and significantly improves pest and disease treatments. Its efficiency means growers can reduce pesticide use by up to 70%, lower application frequency, and skip pH adjustments, all while achieving superior results. Suitable for all growth stages and plant types, Transport is compatible with a wide range of foliar-applied nutrients, biological controls, and natural pest agents, making it a versatile solution for preventative and corrective care.

Green Planet Karbo Boost

Karbo Boost is Green Planet’s premium powdered carbohydrate supplement designed to fuel beneficial microbial activity during the flowering stage. By supplying a balanced source of simple carbohydrates, it energises the rhizosphere, encouraging microbes to expand and break down nutrients into more plant-available forms. This results in healthier roots, improved nutrient absorption, and more vigorous flower development. With a stronger microbial population, plants are able to maximise nutrient uptake, water efficiency, and oxygen exchange, key factors for maintaining growth momentum during the demanding bloom cycle. The outcome is denser buds, richer aromas, and superior flavour expression in the finished harvest. Karbo Boost is clean, pH-neutral, and easy to use across soil, coco, and hydroponic systems. Its dry powder formulation dissolves rapidly, leaving no residue, and integrates seamlessly into any nutrient program. Growers can rely on it as a consistent energy source that supports both plant vitality and microbial diversity throughout bloom. Regular use of Karbo Boost helps deliver bigger yields with enhanced aroma and taste, making it a go-to supplement for anyone seeking both quality and quantity in their harvests.

Green Planet Back Country Blend Boost

Back Country Blend Boost is a granular bloom additive formulated to deliver a powerful, targeted nutrient punch at the exact time plants need it most, during flowering. Designed as a companion to Back Country Blend Bloom, this booster increases phosphorus (P), potassium (K), calcium (Ca), and humic acid availability, ensuring explosive flower formation, enhanced aroma, and vivid colour expression. Its unique slow‑release profile makes it ideal for outdoor growers seeking simplicity and consistency, just one top dress provides weeks of dependable feeding. What sets Boost apart is its ability to strengthen both the plant and the soil simultaneously. The elevated levels of phosphorus and potassium fuel dense, heavy flowers, while calcium reinforces plant structure and cell walls. Added humic acid improves soil structure, boosts microbial activity, and enhances nutrient mobility, ensuring minerals flow efficiently to where plants need them. This synergy not only drives floral performance but also improves the overall health of the soil environment for future cycles. Unlike liquid bloom additives that require constant reapplication, Back Country Blend Boost offers a clean, dust‑free, and easy‑to‑use granular format. Its controlled‑release delivery makes it a true set‑and‑forget solution, perfect for large outdoor gardens or growers who prefer a low‑maintenance, high‑return approach. By combining ease of use with professional‑grade performance, Boost helps growers achieve bountiful, flavourful harvests with less effort. From backyard growers to large‑scale outdoor cultivators, Back Country Blend Boost is the simple, effective way to supercharge flowering while building healthier soil.

Green Planet Root Builder

Root Builder is Green Planet’s powerful root‑zone inoculant, formulated with two highly active beneficial bacteria, Bacillus licheniformis and Bacillus subtilis. These microbes colonise the rhizosphere to enhance nutrient availability, improve soil structure, and strengthen natural plant defences. B. licheniformis rapidly breaks down nutrients into bioavailable forms, while B. subtilis produces antifungal compounds that protect roots against harmful pathogens. Together, they drive vigorous root growth, improve moisture retention, and stabilise pH, creating a stronger foundation for plant development. By promoting a healthy, living root zone, Root Builder reduces stress, supports nutrient efficiency, and allows plants to dedicate more energy to growth and flower production. The result is a more resilient crop with stronger roots, healthier foliage, and higher yields. Safe and effective across hydroponics, coco, and soil, it integrates seamlessly into any nutrient program. Root Builder contains no synthetic additives and is designed to work naturally in harmony with your existing feed schedule, providing consistent results from veg through bloom.

Green Planet PK Spike

PK Spike is Green Planet’s concentrated bloom-phase accelerator, delivering a clean 0‑14‑15 ratio to push phosphorus and potassium exactly when flowers need it most. This highly soluble formula shifts plant energy toward flower building, driving rapid bud initiation, increased floral density, and a stronger finish. It’s engineered to stack neatly on top of any base program (GP3, Dual Fuel, etc.) without unnecessary fillers, just precision P and K for serious bloom performance. During mid‑flower, plants demand large amounts of phosphorus for energy transfer and potassium for carbohydrate production, cell strength, and oil synthesis. PK Spike answers that demand with a potent shot of both, helping crops set heavier sites, ripen uniformly, and maintain quality under high-light or heavy-feeding conditions. Its low‑residue inputs keep reservoirs and lines clean while delivering fast plant availability. Use PK Spike as a targeted tool from early‑ to mid‑bloom to amplify yield and quality. With correct timing and rate, you’ll see tighter stacking, improved resin output, and a confident, consistent finish across cultivars and environments.

Green Planet Plant Guard

Plant Guard is Green Planet’s premium potassium silicate supplement designed to fortify plant structure and resilience. By depositing silica directly into cell walls and epidermal layers, it strengthens stems and branches, enabling plants to carry the weight of heavy flowers without bending or breaking. This added structural support is invaluable during the flowering stage when blooms demand maximum stability, but also during vigorous vegetative growth to prepare plants for training and canopy management. Beyond physical reinforcement, Plant Guard enhances a plant’s natural defences against stress. Thicker cell walls reduce moisture loss and improve tolerance to temperature swings, drought, and high VPD conditions. They also act as a defensive barrier against pests and fungal pathogens such as powdery mildew and grey mould, helping crops remain healthier throughout their lifecycle. Stronger internal structure also improves nutrient and water transport, ensuring plants feed efficiently and consistently. This leads to faster growth rates, increased vitality, and higher overall productivity, especially under high‑intensity lighting or heavy‑feeding programs. Plant Guard is clean, fully soluble, and low‑residue, making it ideal for hydroponic and recirculating systems as well as soil and coco. It integrates seamlessly into any nutrient program, including GP3 and Dual Fuel, ensuring easy adoption for growers of all scales. With regular use, expect sturdier frames, improved stress resistance, and reliable harvests with superior crop quality.
