Growing Media - Hydroponics

Growing media is a mixture of nutrients, water, and air that aids plant growth.

The Media offers much-needed support to the plants, while added fertilisers supply the nutrients. Water and air are contained within the media's pore spaces.

CANNA, EcoThrive, BioBizz, Gold Label, Jiffy, Mills Nutrients and House and Garden are just a handful of the brands available at Green Spirit.

If you require any assistance or advice, our personnel in our shops in Sheffield and Barnsley are always willing to assist because they are knowledgeable and love what they do.

Growing with added UVA and Far Red.

Photosynthetic Active Radiation or PAR refers to the spectrum of electromagnetic radiation that is visible as light. Plants use this light energy to drive photosynthesis, grow and reproduce. The spectrum is measured in nanometers (nm) and for many years it was agreed that the range of visible light (PAR) sits between 400nm and 700nm. At the low end of the PAR range is blue light and at the upper end is red light.

Recent plant research suggests that expanding the spectrum of light outside of the “traditional” PAR range has significant effects on plant behaviour and that usable range is 380nm to 780nm.

The Dio-Tech UVA/FR Light Bars does just that. It extends the spectrum to include not only visible light, but also UVA and Far Red, for optimal plant performance.

What are the benefits of UVA?

Electromagnetic radiation with a wavelength between 315nm and 400nm is classed as UVA. This wavelength induces a stress response within the plants, much as it does in humans, to develop compounds that will protect its cells from being damaged by prolonged exposure.

Receiving UVA radiation stimulates the plants natural defences and encourages it to develop thicker, waxier leaves. This helps protect the plant against biotic stress factors, like pests, fungal and bacterial pathogens. Research also suggests that UVA deters certain species of sucking insects.

Most importantly, exposure to UVA during the flowering period stimulates the production of resin, terpene and flavonoid compounds, and increases biomass.

We are currently nursing back to health some Mint herbs which were virtually deceased around a fortnight ago. With some TLC and the correct conditions, they are thriving. We replanted them into our air pots for maximum aeration. Using the new LEC reflector for maximum light dispersal,  the mint, along with some chillies and tomatoes are coming along nicely. In our other grow tent, we are using the new Revolution Deva to give our tomato plants the best chance of producing healthy, juicy tomatoes.
