Far-Red Lamps

In the summer of 2015, I decided to design an experiment with a few far-red lamps I had been waiting to use. The purpose of this experiment was to test and record the changes, if any, of adding far-red lamps to a controlled indoor grow. I hoped the far-red light would induce early flowering in the few plants placed directly under the added light.

Lighting

As another year draws to a close, now is a good time to reflect on how our gardens have performed over the last 12 months. How have they developed and what – if anything – did we learn? As, I’m sure, many of you will be winding down to enjoy the festive period, take a few minutes out from devouring masses of food and – hopefully – your recently harvested green and start planning for the New Year.

First there was light!

Light is the most important aspect in our grow space. There are other aspects that are required in order to have a successful grow, light however is the single most important aspect as without it nothing else can function.

A crash course into LED growing

Despite LEDs (Light Emitting Diodes) being around from the 60s and indoor growing being practiced quite extensively the past decades, a successful marriage of the two doesn't seem to have happened yet. As a technology, it failed to grasp the imagination of growers and most see it as an inferior lighting that at best can be used as supplement. But do LEDs produce inferior lighting conditions than traditional HID lamps, or is it that the technology...

The People Speak!

About a month back I found myself down in London, partaking in one of my favourite past times; wandering into a local grow shop and having a good old chinwag with the bloke behind the counter. It fascinates me how different areas of the UK prefer different growing styles, nutrients, lights and strains, plus - if they're not too busy with customers - the owners generally like to have a natter.

SEALED A/C ENVIRONMENT

I am building a closed system garden that will be lit by 6000 watts of HPS and the canopy will cover an 11 M2 space. It will be cooled using a 24,500 BTU window-style a/c venting the heat outdoors.

LIGHT HEIGHT

My garden is lit by a 600-watt lamp that is at its top height, 165 cm. Two of the three plants are 110 cm, so the plant tops are only 55 cm from the lamp. I am worried that the tops will burn if they get too close to the lamp.

LED Trial with Critical Jack

Light emitting diodes (LEDs) are used to take a plant from seed to bud.Light emitting diodes are electroluminescenct, they use small doped semiconductors to emit light. They have two leads, a positive and a negative. When current is applied from positive to negative, they produce light. The individual diodes are usually 1 to 5 watts each, with several wired together to make a single light fixture. For example, a single 30 watt LED light might be manufactured...

UVC LIGHTS

Do germicidal UVC lights have any place in an indoor garden? Are they as harmful to plants as they are to humans? I am looking for ways to provide a cleaner environment for the plants.

HARDWARE STORE EQUIPMENT

Can I use the HPS, MH and CFL lights that are for sale at hardware stores or should I just go to the hydro store and buy them. I don't trust that the hydro store is safe because of all the stories I hear about the police.

INDOOR-OUTDOOR CULTIVATION

Where I live, I get full sun all year long and the winters are extremely mild. The minimum temperature is 150.If I germinate indoors and grow the plants vegetatively to 75cm under HPS and place the plants outside during the "winter„ period will the short light period induce flowering? If they get full sun will they finish off in 6 to 8 weeks, just like indoors?
