Grow Light Introduction

 

Lamp size & type

The lamps size (wattage) and type (spectrum) is essential for ensuring plants receive adequate light. When using HID or fluorescent lamps, lux* meters are useful for checking if all foliage is receiving the correct amount of light . Ensure to check both high and low:

Clones /seedlings: 5,000–7,000 lux. Use fluorescent.
Vegetative growth: 15,000–50,000 lux. Use MH lamp.
Flowering: 45,000–70,000 lux. Use HPS lamp.

*PAR meters are more accurate and can also be used to test LED lights, however they are very expensive.

Too little light?
Can be caused by foliage being too far from the lamp i.e. lamp is too high, or plants are too tall, or area of coverage is inadequate (see below). May also be due to shading from over-planting, inadequate plant shaping/ training, incorrect lamp size/type, or due to a faulty lamp or incompatible ballast. Insufficient light will produce sparse foliage, spindly branches and poor flowering.

Too much light?
Can be caused by the lamp being too close to foliage or incorrect lamp size. Symptoms will be evident on upper most foliage and may include stunted growth, and folding, bleaching or burning of leaves.

Area of coverage
The lamps wattage will largely determine the size of the ‘effective’ growing area – see Fig 3.3 and Table 3, “Area of coverage”. However, to unleash the lamp’s full potential, it is critical to also choose a lamp shade that provides maximum reflection efficiency and focuses the light evenly (without hot spots) and with the correct amount of spread i.e. not too wide or narrow. The use of reflective material on walls and other large surfaces helps ensure that light is not wasted through absorption.

Plant height
Light intensity diminishes rapidly as distance from the lamp increases. Therefore, along with choosing the correct wattage, it is important to ensure the majority of foliage is positioned within lamp’s “sweet-zone”. This is best achieved by training plants into a low, wide and flat canopy (Fig 3.2) – see section on Topping and LST (Fig 8.1).

Lamp height
To best utilize lamp output, position the lamp as close as possible to the top of plants without causing photo-respiration or burning of foliage (see Table 3 for “minimum gap” guidelines). Air cooled lights should be used because they enable lamps to be positioned closer to the foliage. These are particularly beneficial for 1,000W lamps (Fig 7.2). Ensure lamps are hung so that their height can be easily adjusted as the plants grow.

Plant density / shading
Shading becomes an issue when plants are positioned too close to one another. It is generally more productive to plant fewer plants, rather than more.

Topping and LST training by Floramax

How to prune and train plants to achieve higher yields

Indoor grow lightsTo obtain higher yields, the most productive indoor growers manipulate their plants into a low, wide and flat canopy with multiple flowering sites at the ‘same’ vertical height. This allows a larger proportion of your plant to bask in the “sweet zone” enjoying optimum light levels within a temperature range that is ideal for photosynthesis.
This ‘form’ can be achieved through a combination of “topping” followed by Low Stress Training (LST):
1. Topping is effectively used to obtain multiple, even-sized floral sites.
2. LST is then used to bring these floral sites to the same height to maximize grow lamp efficiency.

STEP 1. Topping. When and how to ‘top’?

topping a plantTopping is best done when the plant is very young (less than 2-3 weeks old) and has only 2-5 nodes in total. Topping is the removal of the plants ‘top’ growth just above a node (fig 2). Once topped, the two axillary buds immediately below the cut will then grow out into two new branches. Once these new branches grow out to 1 or 2 leaf sets (or nodes) they can be topped again (Fig 3a). This second round of topping will grow out to form four even-sized branches (potential bud sites – see fig 3b).

Important points for topping:

1. Topping can be done more than twice however doing so will increase time in vegetative phase. Test to see what is most productive. Some experienced growers will top up to 5 times (or more) to obtain 32 branches and can be well rewarded for their efforts.Topping & LST

2. Healthy plants usually take 2-3 days to recover from topping. After topping, do not remove the leaves from that node as these are needed to power growth of the branches from that node.  Never top during flowering as it causes too much stress – which slows growth and inhibits yield. Do not top unhealthy plants. Also, avoid topping older, thicker growth as this takes longer to heal.

STEP 2. Low Stress Training (LST)

After topping (done twice in the scenario above – Fig 3b) there are four quality branches (or bud sites) growing vertically from what was originally the top node. LST involves pulling these branches downwards (to horizontal) and outwards (i.e. “star” configuration) so that all four branches are spread apart from one another, horizontal and at the same height (Fig 4). The lower branches from the nodes ‘below’ where topping occurred are now also closer and more exposed to the light. As these grow up they can be topped and manipulated using LST.

Important points for LST:

low stress training (LST) plants1. When to start and finish LST?  LST should be started as soon as possible during the vegetative phase. Flowering phase can commence once all major branches are horizontal and level with each other. Budding can be triggered by switching lights to 12-on, 12-off. LST should continue during early flowering as vegetative growth continues. Maintain a flat, level branch structure. Vegetative growth will eventually stop when the plant is putting most of its energy into flowering.  Minimal adjustment is required after this point – apart from keeping shade away from key areas.  It can be beneficial to remove small, lower growth as this helps improve ventilation through the canopy and prevents infestations or infections due to foliage being in contact with soil.

2. Bending branches: Young growth is easier to bend than older growth. Also some species/ strains are easier than others. Do not rush to get branches horizontal, do this in stages. When a branch is first bent, growth will be slowed. Foliage will re-orientate towards the light then eventually start to grow. LST again once it grows another 3 inches or so.

How to secure branches for LST?

Adopt a method that is strong enough to support the plant during flowering and allows access to manage the growing plants, conduct cleaning and other maintenance:

screen or netting for LST1. Gardening wire or landscape stakes: This method is effective during the early growth stages soon after topping.  Branches can be held in place with wire that is anchored to screws in the pot, or some other structure.  As the plant grows the wires need to be tightened however ensure the main stem remains vertical.

2. Screen or netting:  A square or rectangular frame needs to be securely erected with either netting stretched over it or create a grid pattern using string woven through eyelets that are screwed into the frame.  The holes in the grid or netting need to be at least 2×2” or 5x5cm.  Depending upon the species, the screen is normally mounted low enough (approx 1-1 ½ ft / 30-45cm) from the plant’s base so all the lower branches can grow up to the screen and gain access to direct light (Fig 5). As the plant grows, the growing tips need to be lowered back under the netting and directed into the next empty space in the screen.

GOT SHINGLES? USE CANNABIS!

If it could happen to anyone, it usually does to me. In this case, I am one of those people who had chickenpox as a child and the varicella-zoster virus didn’t want to stay dormant in my adult nerves, giving me shingles… three separate times.

Ask those who have experienced it and they will tell you, shingles is excruciatingly painful. Treatments include skin patches with painkillers put directly on the area and nerve-affecting drugs such as gabapentin or lyrica; but, most people need opiates to deal with the level of pain that it causes and doctors are happy to prescribe them.

Lucky for me, I know an incredible secret; cannabis and its effects make it one of the best and most effective options when it comes to shingles. The level of relief that it brings it unfathomable and if it ever happens to you, this is what you need to know.

What is shingles?

Shingles is a viral infection of a sensory nerve connected to an area of skin. It is characterized by the rash that appears and the painful symptoms it causes. It can cause a great deal of pain as well as other symptoms such as fatigue, nausea, severe muscle aches and flu like symptoms. The pain is pretty intense and I like to describe it as coming in a few forms.

What does shingles feel like?

Essentially, I have narrowed down the three different types of pain that you experience when you have a shingles rash:

1, You know the feeling that you get when you take a bad burn off of ice or cold water? The surface of your skin feels that way wherever you have the rash. I would rate this pain level at a solid 9 out of 10.

2, It comes with severe muscle pain. I have had it both times on my neck and shoulder and it felt like I broke my collarbone. I could hardly lift my arm and it caused some seriously weird shooting pains down my arm.

3, You can feel the length of your entire nerves themselves, right from the edge of your skin down to the bone; the rash sends lightning shocks through each one. It is a very bizarre and stressful sensation and the worst part is that you never know when it is coming.

How could cannabis help?

Topical Cannabis

If you have had chickenpox, then you could get shingles and it would be wise to go out right now and make sure you are fully stocked with topical products. The amount of pain relief that a cannabis cream can give is miraculously effective and instantaneous; the second its on the rash, the bad burn pain excruciating drops from a level 9 to a 2.

Edibles

I don’t think I would ever be able handle a shingles outbreak without high THC, edible cannabis. The type of pain I described as electric shocks throughout the nerves can literally cause severe anxiety because its so weird and uncomfortable. Like hitting a mute button, the moment I felt the effects of the edible starting to take effect, it was like it sent all the shocks and pain far away to someplace else.

With such a large concentration of pain receptors residing in the intestines, using edible cannabis to effectively treat the pain caused by shingles, makes sense and it works.

I can’t explain this but it’s true

I swear that using cannabis to deal with the symptoms of my shingles outbreak made me heal faster; I can’t tell you exactly why but I imagine it has something to do with the neuroprotective properties of cannabis.

In most cases, you can expect shingles to last between 3 to 5 weeks. The longest it has ever taken my body to fully heal, start to finish was 10 days… I really believe I healed faster thanks to cannabis.

For me, the onset has always been rapid but I noticed that the second I saturate the area in THC, it slowed right down. Yes, I started taking antiviral medication immediately all three times but the effect that cannabis had on the area was instantaneous. Taking the antiviral medication was nowhere near as quick or obvious in taking effect.

Cannabis plays a huge role in promoting proper nerve function for conditions such as Epilepsy and MS so it makes sense to me that it could make a big impact in treating an infected nerve.

What to do if you have shingles right now

  • Go to your local dispensary and overstock yourself on edible and topical products. Despite whatever legal status they might be operating under, you will need to go to a dispensary because licensed producers don’t sell either of these life saving products.
  • Try to relax and de-stress as much as possible. The more you sleep and relax, the easier it is for your body to regenerate.
  • Drink lots of fluid and eat food that provides your body with benefits, not takes them from it.

1 in 3 people are going to experience shingles. If there was one thing I could say to everyone who is or is about to get a shingles outbreak, it would be that for me, having shingles three times was easy, not really painful and no big deal…as long as I had enough cannabis.
