A One-Bottle Base Feed That Behaves Like a Three-Part System
Solo-tek Grow is Grotek's one-part vegetative base nutrient, built to give growers the immediate responsiveness of a multi-part mineral feed alongside the steadier, biology-friendly release of an organic one. Rather than splitting macro and micronutrients across separate bottles, the formula blends mineral salts with organically-derived plant nutrients, amino acids, vitamins, enzymes and kelp-derived compounds into a single concentrated suspension.
The thinking behind combining the two nutrient types is cation exchange. In recirculating hydroponic systems, mineral nutrients react quickly and let growers correct feed on the fly, but in coco or soil that same mineral nutrient binds to the substrate and takes longer to reach the roots, creating a lag. Solo-tek Grow's organic fraction is designed to keep feeding the plant through that lag, so the crop gets consistent nutrition regardless of which medium it's growing in.
Because the formula is heavily concentrated and carries a high level of humic acid, only small volumes are needed per litre of feed water, and the humic content also supports beneficial biology in the root zone. It's built to be used from the seedling and clone stage through to the point the plant is switched over to a flowering formula.
- Single-bottle simplicity - one product instead of managing multiple grow-stage bottles
- Mineral and organic nutrition combined - fast mineral response plus steady organic release
- Formulated for vigorous vegetative growth - supports canopy development from an early stage
- High calcium content - backs strong plant structure through the vegetative phase
- Works across media types - suited to hydroponics, NFT, aeroponics, coco and soil
- Highly concentrated - low application rates keep a bottle going further
Technical Specifications
NPK: 6-3-7.
Growth stage: seedling/clone through to pre-flower.
Application rate: 1-2ml per litre of feed water (approx. 1 litre yields up to 500 litres of nutrient solution).
Suitability: hydroponics, NFT, aeroponics, coco and soil.
Note: this is a nutrient suspension, not a solution - agitate/shake well before use.

FREE Express Delivery on orders over £60. We aim to post same day for next-working-day arrival — order by 3pm Mon–Fri. Delivery is 1–2 working days. A few harder-to-stock or large, bulky items can take a little longer — we'll tell you if that applies to your order.
