Halo Powder

£26.50
HALO is the first product of an entirely new class of plant growth additives utilising the Harpin Alpha Beta protein, a powerful new plant technology. HALO is foliar applied or used as a seed or tuba pre-treatment. Halo’s unique natural protein leads the plant to believe it is under attack, this ‘tricks’ the plant and naturally forces the plant to ‘defend itself’ turning on stress-defence and growth systems and reproducing very rapidly. If a plant ‘believes’ it is under attack, it will grow and reproduce at rapid rates as a means of ensuring it’s survival. This results in a healthier and more productive plant with an increase in crop vigor, stamina, nutrient uptake and reproductive growth (depending on time of application). Both laboratory and field studies have shown that HALO treated plants exhibit accelerated growth, earlier flowering and early/increased fruit sets. These observed effects on growth and development will lead to a stronger, healthier plant, that is less susceptible to disease with increased yields and a shortened time to harvest.

Hesi Boost

£10.00£18.00
Many plants need a trigger to switch from their growth phase to start their blooming phase. This can be external stimuli such as light, temperature or simply after the passage of time, but also nutritional enhancement. Boost contains a large number of natural sugars, minerals, enzymes and fruit acids from plant extracts and fruit extracts that have a strong effect on flowering. We start to give Boost at the end of the growth phase to stimulate our green friends to flower. The process that the plant goes through, in order to start this flowering phase, is quite intense. A lot of things are happening inside the plant, which requires regular use of Hesi Boost. During the flowering phase, we use Boost continuously to keep the flowers in top shape. It increases leaf density and improves the overall plant condition. • Boost is a very efficient foliar fertiliser. • Induces and strengthens flowering. • Long lasting fruits with high sugar content.
