Under lighting

[sir-scrogalot]

My biggest issue right now is how I'm going to mount/suspend the lights from underneath

Ive side bolted mine to my Ish150 so all hanging from one light can send you pic for a laugh if you lik
mrnice handy work lol

Yeah post it in here

Hey sir-scrogalot

Heres my dodgy handy work lol





DR8 is on in the pic the otherside is the FR8

Nice set up. Is that in a 60x60?

Yh the tent is 60x60x140

So you guys wanting to try this... Might want to watch this video and pay close attention to which way the leaves and stems want to grow....

Plants can sense gravity. Just saying

"The Side Lighting
In so many situations, supplemental lighting is an excellent choice. However, it is sure not similar to side lighting, which is not as useful to a cannabis grow room much of the time.

When do you use side lighting?

It is generally used with fluorescent grow lights, an example being T5 grow lights and compact fluorescent lights (CFL). These are used on younger marijuana plants that are not yet trained. Why use these lights in conjunction with the side lighting?

It is because they aren’t powerful enough to get far down into the marijuana plant, which is not ideal, if you want the best bud growth.

Fluorescent lighting is weak enough to only cover a few inches of the plant’s canopy. So, by the time that the marijuana plant is about one foot from this lighting, it is not as useful, but with side lighting, it increases the potential to reach the marijuana buds within a few inches.

Side lighting may also be used by cannabis growers that grow plants in very cramped growing spaces. In these small spaces, the light from above isn’t able to effectively bounce from reflective walls to reach the lower branches of the canopy.

In this case, side lighting may be beneficial to stimulate photosynthesis in the lower part of the plants.


On the flip side, very large grow rooms can have certain areas that don’t receive the right amount of lighting. In these large-scale facilities, plants that don’t receive enough light aren’t able to metabolize the correct amount of nutrients from its heavy feeding schedule.

Side lighting can help plants stimulate growth, absorb nutrients, and prevent nutrient disorders.

If the cannabis plants are trained to grow shorter and flatter, you will be able to increase the yields using the same amount of lighting since all the main marijuana buds can be shifted to the top while receiving full levels of light.

In other words, although, you may have a weak grow light using fluorescent lighting, you will be able to get more yields by growing the marijuana plants that are flatter and wider in comparison to using side lighting.

When the marijuana buds are close to the top, even a T5 grow light can result in better yields since each bud at the top is closer to the light and because the plant has been trained to lay flat along with the screen."

interesting stuff , For me side lighting must help to some degree

[KD]

Yeah I'd agree side lighting is beneficial as it gets light to the tops of the leaves, but from the side. Under lighting though is just going to be a waste of money.

I mean side lighting has some possible benefits , after all the sun isn't directly over plants all day but I'm struggling with the concept of under lighting tbh. Seems like spending money for no reason to me but will be interested to see what u do.

I heard of a French geezer growing vertically using side lighting to supplement the whole light schedule.

Very interesting.
