Whether you’re a novice or an experienced gardener, this nutrient additive ensures your plants achieve their best growth and highest yields, leading to a healthier and more productive garden.
Although this is a relatively new product to us at Greens, the few bits of feedback we have had has been very good, so we'd recommend this to anyone who's looking to push their plants' potential that little bit further.
Highly concentrated for increased value for money, it's designed to be used in weeks 5, 6 and 7 (depending on crop type) of the flowering phase - it can also be used from week 3 (or when plants have fully entered the flowering phase) at 0.2ml/l. When plants are at the business end the idea is to then double the dose in weeks 6 and 7 to 0.4ml/l. As always, keep an eye on your plants - look and listen to them!
NPK - 3-9-19
Available in 250ml and 1l sizes.
