Horticultural Lights

With the onset of cheap, nasty, home made, dangerous lights that have dogged the hydroponics market, we thought it best to say a few words. There are lights and there are proper horticultural, professional grade lights on today's market. The former are quite frankly death traps; they are constructed from the cheapest, obsolete, end of the line components that are usually mismatched and wrongly configured. To think that these poorly built, badly wired, misconfigured lights are gracing people's damp, humid and sometimes wet grow rooms is a scary thought, especially if it's in the home. And all in the name of bargain. Not only do you risk your own life with these tacky lights but everybody that lives with you. So don't do it! Look before you leap!

Our lights all carry CE certifications and have BS approved components. They are made by horticultural lighting companies that have built lights for the hydroponics trade for over a decade. They are professional grade, no hassle lighting units that have all been personally tested, and demonstrated by ourselves. They all carry a two year parts and labour manufacturer's guarantee (except for the lamp). The 250W, 400W, 600W and 1000W are all high pressure sodium and metal halide compliant, so the on light can run either lamp. Lighting is possibly the most important decision for indoor horticulture, cheap normally represents a health risk. For the sake of saving £50 is it worth it? You have been warned!

Standard High Pressure Sodium Range

Industry standard worldwide for horticulture. High Intensity Discharge sold with Plus, Agro or Planta lamps which have enhanced blue spectrum for vegetative growth and red spectrum for flowering growth. Reliable and efficient to run. The approximate cost for a 400W HPS on a daily 18 hour cycle is £35 - £40 per quarter. All lights are CE certified and guaranteed. Made by leading horticultural lighting companies from Holland and England. All thorough testing and approval worldwide. These lights are far from home made, unlike other cheap lights on the market. Buying lights without CE Certification is like buying a car without an MOT.

Finally, please note that the green and white ballasts depicted are of equivelent quality and are supplied across the range of lighting combos. "Standard", "Quality" and "Air Cooled" refer only to the differences in the reflectors supplied.

See our fully equiped and stocked shop and warehouse, as well as our basement and upstairs demonstration grow rooms, fully operating equipment and systems on show. We will be happy to talk you through the systems and equipment. Got any questions - we can answer them.

Typically the more light you give the plant, the better the yield will be. Double the lux, double the yield. Approximate coverage with:

- 400W is 1m²: 5-10 plants
- 600W is 1.5m²: 7-14 plants
- 1000W is 2m²: 15-20 plants

This steadfast light has been available for a decade and in it's most recent incarnation, is as effective as any modern design. This light is used extensively throughout Holland. It is affectionately known as "The Producer" and has a reputation for consistent and abuntant yields. This light is ideal for indoor use and greenhouse use. The unit is designed specifically to be suspended via two chains at either end of the main section. This counterwieghts the sturdy pentagonal reflector. The unit is approximately 66cm long and the widest section of the reflector is approximately 42cm.

Philips Industria SGR200

Click for a larger view

The SGR200 is an extremely popular product, combining the functions of ballast and reflector in on easy to mount unit. Simply connect to the mains via a timer relay for quick and easy plant growing. Although the SGR200 is not waterproof, it is especially suitable for use in greenhouses or indoor growrooms where space is limited. The SGR200 units can be daisy chained via the integrated junction, although in the interests of safety, this practice is discouraged by Esoteric Hydroponics. Please wire lighting seperately wherever possible. The SGR200 is approximately 80cm long.

The Poot and the Industria are typically used in green house type environments. They can be used indoors however were primarily designed for glasshouses. They are heavy and robust and allow the possibility of daisy chaining one light to another, but this has to be carried out by a qualified electrician. These are top end lights built especially narrow so as not to obstruct the sun, but also give a wide spray of light to complement the sun.

All our lights carry a two year no quibble guarantee. If it stops working then we will exchange it for one that does straight away. No waiting for weeks while other companies get it repaired - we give you another ASAP. If you bring the light down to the shop we will exchange it there and then. (This guarantee excludes the lamp).

High Pressure Sodium lamps are predominately used for the fruit or flowering cycle of the plant's life which is normally governed by the photoperiod typically 12 on, 12 off. Where Metal Halide lamps are predominately used for the vegetative cycle of the plants life a typical photoperiod of 18-20 on and 6-4 hours off. Agros or Plantas are High Pressure Sodiums but with a tweaked blue end so you can veg and flower under the one lamp.

Mercury Vapour Lights

Click for a larger view

Phosphorous coated to promote blue and red spectrum so you can veg and bloom, more blue light that red, a cheap way to get started.

However lamp wants replacing every nine months as lamp can become volatile. Costs more to run and maintain compared to HPS, MH or fluorescents.

250W Suitable for cloning L46 £65
500W suitable for cloning / mother L47 £95

Fluorescents

Emit less light than high intensity discharge although can be used throughout plant cycle but due to brightness will produce small yields. Popular for seedlings and cuttings, an excellent way to establish young plants.
