Organic Veg & Bloom Bundle UK | Cal-Mag + Mycorrhizal Kit

Overview What's Included How to Use FAQ Veg & Bloom Bundle — everything you need for a complete grow, from planting to harvest Complete Grow Kit Choose Your Bloom NPK Cal-Mag Included Mycorrhizal Fungi 16 Organic Inputs Made in Stockport This bundle is a complete organic feeding programme in one order. It contains everything you need to take a plant from transplant through vegetative growth, into flower, and all the way to harvest — with no separate purchases, no gaps in nutrition, and no guesswork. Choose your bloom ratio, choose your veg size, and you are ready to grow. Every product in this bundle is formulated to work together. The Veg and Bloom fertilisers share the same 16 premium organic inputs. The Cal-Mag fills the calcium and magnesium gap that those formulas leave by design. The mycorrhizal fungi colonise the root system at transplanting and massively extend nutrient and water reach for the entire grow. This is not a random collection of products — it is an integrated system built on the same soil science. 4Products 16Organic Inputs 3Bloom Options +Mineral Mix Add-on What this bundle covers Vegetative stage — Veg 4-4-4 — balanced NPK dry amendment with 16 organic inputs including diastatic malted barley, 2.5× the humic acid and double the seaweed of the Premium range; mix into substrate before planting or top dress throughout veg Flowering stage — your choice of Bloom — choose Bloom 2-8-4 (high phosphorus, bestseller), Bloom 2-4-8 (high potassium for sugar loading), or Bloom 2-8-10 (maximum P+K for heavy feeders); same 16 inputs, different proportions Calcium and magnesium — Cal-Mag — powdered supplement with micronised gypsum, pharmaceutical-grade Epsom salt, boron, and fulvic acid; recommended alongside all Veg and Bloom feeds because those formulas are packed with premium biostimulant ingredients rather than bulked up on Ca/Mg Root colonisation — Mycorrhizal Fungi — premium endo and ecto inoculant applied once at transplanting; the fungal network extends the root system by up to 700×, dramatically improving nutrient and water uptake for the entire grow Optional add-on — Mineral Mix — volcanic rock dust, seashell meal, gypsum, and clay minerals for extra calcium, trace elements, and CEC capacity; especially useful in coco substrates or depleted soil Why buy the bundle? The Bundle Approach One order — complete programme from transplant to harvest Every product sized to work together Cal-Mag and mycorrhizal fungi matched to your bloom size Choose your veg size separately — substrate mixers need more veg than bloom No gaps in nutrition, no forgotten products mid-grow All 16 premium organic inputs across both stages Buying Individually Work out which products you need and what sizes Risk ordering the wrong Cal-Mag size for your grow Easy to forget mycorrhizal fungi until transplant day Multiple orders, multiple deliveries, higher shipping cost No guarantee everything arrives before grow day Choose your bloom NPK All three blooms use the same 16 premium ingredients in different proportions. Choose the one that matches your growing philosophy. 01Bloom 2-8-4 — High Phosphorus (Bestseller) Phosphorus-dominant — 8% P drives flower initiation, bud site development, and ATP production. Moderate potassium at 4% supports sugar transport and enzyme activation. The most popular choice with growers new to dry amendments. If in doubt, start here. 02Bloom 2-4-8 — High Potassium (Finishing & Flavour) Potassium-dominant — 8% K drives sugar loading, terpene production, and ripening. Moderate phosphorus at 4% sustains continued flower development. Preferred by growers who prioritise flavour, aroma, and aromatic intensity. Works as a standalone bloom or finishing feed after running 2-8-4 in early flower. 03Bloom 2-8-10 — Maximum P+K (Heavy Feeders) High phosphorus and high potassium — 18% combined P+K, the highest in the range. Built for heavy-feeding varieties that deplete standard bloom feeds. No need to switch formulas mid-flower or add a separate PK booster. One product carries the entire flowering stage. Handcrafted in Stockport. Every product in this bundle is blended by hand using British ingredients where possible — including Scottish seaweed, Yorkshire polyhalite, and British-produced nitrogen and phosphorus sources. No slaughterhouse waste. No synthetic chemistry. Organic ingredients throughout. What's in the bundle: four products, one complete programme 01Veg 4-4-4 — Vegetative Stage Fertiliser A 16-input organic dry amendment with balanced 4-4-4 NPK for the vegetative growth phase. Contains diastatic malted barley (exclusive to Veg and Bloom), 2.5× the humic acid and double the Scottish seaweed of the Premium range. Five nitrogen sources at different release speeds deliver a staggered supply curve — no spike, no crash. Mix into substrate at 5–10 ml per litre or top dress at 2–5 ml per litre every 2–4 weeks. Choose your Veg size separately — if mixing into substrate, you will need roughly double the Veg compared to Bloom. 02Bloom — Flowering Stage Fertiliser (Choose Your Ratio) The same 16 organic inputs as Veg 4-4-4, blended in proportions optimised for flower production. Choose the ratio that matches your growing philosophy: Bloom 2-8-4 — high phosphorus, moderate potassium. Bestseller. Ideal as a standalone bloom or for early-to-mid flower. Phosphorus drives ATP production for bud initiation and development. Bloom 2-4-8 — moderate phosphorus, high potassium. The potassium-forward option for sugar loading, ripening, and aromatic intensity. Preferred for mid-to-late flower finishing. Bloom 2-8-10 — high phosphorus and high potassium. Maximum combined P+K (18%) for heavy-feeding varieties. No need to switch mid-flower or add a separate PK booster. 03Powdered Cal-Mag — Calcium & Magnesium Supplement Micronised gypsum (15% Ca), pharmaceutical-grade Epsom salt (3% Mg), sodium borate (boron for calcium transport), and fulvic acid (natural chelation for improved uptake). pH-neutral — delivers calcium and sulphur (16% S) without shifting soil pH. Zero nitrogen — unlike liquid cal-mag products that use calcium nitrate. We recommend using Cal-Mag alongside all Veg and Bloom feeds because we packed those formulas with the premium biostimulant ingredients rather than bulking up on calcium and magnesium. Use as a root drench (1.5–4 ml per litre), top dress, or soil mix amendment. 04Mycorrhizal Fungi — Endo & Ecto Root Inoculant A balanced blend of endomycorrhizal and ectomycorrhizal fungi species. Applied once at transplanting — dust the root ball or sprinkle into the planting hole so the spores contact the roots directly. The fungi form a symbiotic network that extends the effective root system by up to 700×, dramatically improving water uptake, phosphorus access, and drought tolerance. One application lasts the entire grow — the fungi colonise and persist as long as the root system is active. Optional add-on: Mineral Mix Mineral Mix — Trace Elements & Soil ConditionerVolcanic basalt rock dust, seashell meal, gypsum, and clay minerals. Adds extra calcium, over 60 trace elements, and CEC capacity to your substrate. Particularly valuable in coco substrates (which contain zero minerals), in depleted or reused soil, and for heavy-feeding crops. Mix into substrate at 10–35 ml per litre of soil (1 tablespoon = 15 ml). Use the fertiliser calculator to work out how much you need, and the measurement converter to switch between units. This is an optional add-on — not included in the base bundle price.

Equal amounts of Veg and Bloom is fine The pre-charged soil provides the initial nutrient load Choose the same Veg size as your Bloom size Example: Medium Bloom (1.5 kg) → Medium Veg (1.5 kg) How to use the bundle: complete grow guide from transplant to harvest The full programme in six stepsThis guide covers a complete grow cycle using every product in the bundle in the correct order and at the right time. For detailed application rates and troubleshooting for each individual product, see the product pages for Veg 4-4-4, your chosen Bloom, and Cal-Mag. Prepare your substrate. Mix Veg 4-4-4 into soil or coco at 5–10 ml per litre. If using the Mineral Mix add-on, mix it in at 10–35 ml per litre (1 tablespoon = 15 ml). If growing in coco, add worm castings or compost at 20–30% of the mix for biology, and pre-buffer the coco with Cal-Mag solution (4 ml per litre of water, soaked 8+ hours). Allow 7–14 days for the biology to activate if time permits. Transplant with mycorrhizal fungi. Dust the root ball with Mycorrhizal Fungi powder or sprinkle it directly into the planting hole so the spores contact the roots. This is a one-time application — the fungi colonise and persist for the entire grow. Water in thoroughly with a Cal-Mag drench (1.5–4 ml per litre). Vegetative stage — Veg + Cal-Mag. Top dress with Veg 4-4-4 at 2–5 ml per litre every 2–4 weeks. Apply Cal-Mag as a root drench (1.5–4 ml per litre) every 1–2 weeks in soil, weekly in coco. Use dechlorinated water for all watering — chlorine kills the biology that makes organic growing work. Transition to flower — 50:50 mix. For the first bloom top dress, combine equal parts Veg 4-4-4 and your chosen Bloom. The plant still needs some nitrogen for the initial flower stretch. Continue Cal-Mag at the same frequency. Flowering stage — Bloom + Cal-Mag. Top dress with Bloom only at 2–5 ml per litre every 2–4 weeks. Continue Cal-Mag throughout flower — calcium demand actually increases during bud development. Do not stop Cal-Mag when you switch to Bloom. Stop feeding 2–3 weeks before harvest. Cease all top dressing and Cal-Mag. Organic growing does not require a synthetic-style flush — simply allow the plant to draw down remaining nutrients from the substrate naturally. Water with plain dechlorinated water until harvest. Water quality mattersUse dechlorinated water for all watering and Cal-Mag drenches. Leave tap water to stand for 24 hours, use a carbon filter, or add a dechlorinator. This single step makes the biggest difference to how well the entire programme performs. Water thoroughly but not to heavy runoff — excessive drainage flushes your dry amendments and Cal-Mag out of the root zone.

Store all products sealed in a cool, dry place. Frequently asked questions about the Veg & Bloom Bundle Why can I choose the Veg size separately from the Bloom size?Because growers who mix Veg into their substrate before planting need roughly double the Veg compared to Bloom. The Veg amendment is used in bulk at the soil-mix stage and then again for top dressing during the growth phase. If you are using pre-charged soil and only top dressing, equal amounts of Veg and Bloom works fine — choose the same size for both. Which bloom should I choose — 2-8-4, 2-4-8, or 2-8-10?All three use the same 16 premium ingredients in different proportions. Bloom 2-8-4 is the bestseller — high phosphorus, moderate potassium, ideal as a standalone bloom. Bloom 2-4-8 shifts the balance toward potassium — preferred for sugar loading, ripening, and finishing. Bloom 2-8-10 delivers maximum P+K for heavy feeders. If you are new to dry amendments, start with 2-8-4. Why is Cal-Mag included — don't the fertilisers contain calcium?The Veg and Bloom fertilisers do contain calcium from polyhalite, rock phosphate, and basalt. But those formulas are packed with the premium biostimulant ingredients that drive results — biochar, humic acid, seaweed, malted barley — which left limited room for the full Ca and Mg that fast-growing plants demand. The Cal-Mag fills that gap with a pH-neutral, zero-nitrogen powder that includes boron for calcium transport and fulvic acid for chelation. When do I apply the mycorrhizal fungi?Once, at transplanting. Dust the root ball or sprinkle the powder directly into the planting hole so the spores make contact with the roots. The fungi colonise and persist for the entire grow — you do not need to reapply. For best results, apply before the roots are established so the fungi colonise early and extend the root network from the start. Does this work in coco coir?Yes. Add worm castings or compost at 20–30% of the coco mix to introduce the microbial life that breaks down organic matter. Pre-buffer the coco with Cal-Mag solution (4 ml per litre, soaked 8+ hours) before amending with Veg 4-4-4. Use the upper end of the dosage ranges and apply Cal-Mag weekly rather than fortnightly. Do not water to heavy runoff. Can I use this with autoflowers?Yes. Use the lower end of the Veg dosage range (5 ml per litre soil mix, 2 ml per litre top dress) as autoflowers have a shorter vegetative stage. When pre-flowers appear, use a 50:50 Veg/Bloom mix for the first bloom top dress, then switch to Bloom only. Apply Cal-Mag and mycorrhizal fungi exactly as described for photoperiod plants. Do I need to flush before harvest?No. Organic dry amendments do not leave synthetic salt residues. Stop all feeding 2–3 weeks before harvest and allow the plant to draw down remaining nutrients naturally. Water with plain dechlorinated water until harvest. Do I need the Mineral Mix add-on?It is not essential but it is recommended — especially in coco (which contains zero minerals), in depleted or reused substrate, and for heavy-feeding crops. The Mineral Mix adds extra calcium, over 60 trace elements, and clay CEC capacity that helps the substrate hold nutrients instead of losing them to drainage. Mix into substrate at 10–35 ml per litre (1 tablespoon = 15 ml). Use the fertiliser calculator to work out how much you need. Do I need to pH my water?No. Microbial activity in healthy living soil naturally buffers pH into the optimal range. The clay minerals, biochar, and humic acid in Veg and Bloom all contribute to this buffering capacity. Simply water with clean, dechlorinated water. Can I reuse my soil after harvest?Yes — this is one of the primary advantages of organic dry amendments. After harvest, remove old roots, break up the substrate, and re-amend with Veg 4-4-4. You do not need to add more mycorrhizal fungi — the existing colony will persist as long as the substrate has not been sterilised. Top up Cal-Mag and Mineral Mix if desired. The soil improves with each cycle. How long will the bundle last?It depends on pot size, plant count, and whether you are mixing into substrate or only top dressing. As a rough guide: the Small bundle (750g Bloom) covers 1–3 plants in 10–20 litre pots for a single cycle. The Medium bundle (1.5 kg Bloom) covers 3–6 plants. The Large bundle (3 kg Bloom) covers 6–12 plants or multiple cycles with fewer plants. Use the fertiliser calculator to work out exact quantities. What is the difference between this and the Premium Tomato or Rose fertiliser?The Premium range (Tomato, Rose & Flower, Fruit & Veg) is designed as a single product to carry the entire grow with crop-tuned NPK ratios. This bundle splits the grow into veg and bloom stages with separate, stage-specific fertilisers — each loaded with more of the premium biostimulant ingredients (2.5× humic acid, double seaweed, exclusive malted barley) because growers who split stages expect the best at each phase. The bundle approach gives you more control and higher input quality per stage. Does anything contain slaughterhouse products?No. No bone meal, blood meal, feather meal, or slaughterhouse by-products anywhere in the bundle. The only animal-derived ingredient is mealworm frass (insect castings) in the Veg and Bloom fertilisers. All other inputs are plant-based or mineral. How should I store everything?Store all products sealed in a cool, dry place away from moisture and direct sunlight. Shelf life is several years for the fertilisers, Cal-Mag, and Mineral Mix when kept dry. The mycorrhizal fungi should be stored in a cool, dark place and used within 12 months for best viability — the spores are living organisms.
