Description
A kelp-based tonic to power vegetative growth
Seaweed from Advanced Floriculture is a professional-grade vegetative tonic made from kelp, supplying vitamins, minerals and natural growth-stimulating hormones. It gives plants an extra push through veg before you switch to Seafuel for flowering, and delivers in any growing medium.
Key Benefits
- Kelp-based as a natural source of vitamins and minerals
- Growth-stimulating hormones to drive vegetative development
- Works in any growing medium
- Simple addition to an existing veg feed schedule
Weak or slow vegetative growth?
Sluggish veg growth often comes down to a feed missing the wider range of natural compounds a plant would find in the wild. Seaweed's kelp-derived hormones, vitamins and minerals build a stronger, healthier base before the switch to flower.
How to Use
- Veg feed: add at 0.5ml per litre in soil and in recirculating or DWC systems, or 1ml per litre in run-to-waste, during the vegetative stage.
- Switch to Seafuel once plants move into flower.
| Stage | Per 1 L | Per 10 L |

| Soil, vegetative stage | 0.5 ml | 5 ml |
| Recirculating and DWC, vegetative stage | 0.5 ml | 5 ml |
| Run-to-waste, vegetative stage | 1 ml | 10 ml |
