1. Light Coverage Formula (C = A/(N x S))
C stands for the total Coverage area needed to light up your grow room effectively.
A represents the Area of your plant canopy that needs light.
N is the Number of lights you have in your grow room.
S refers to the coverage Size or area that each individual light can illuminate.
Purpose: This formula helps you calculate how to evenly light your entire grow area, ensuring every plant gets the light it needs. By adjusting the number of lights (N) or the coverage area of each light (S), you can achieve the perfect lighting setup for your plants.
Example: If your canopy area (A) is 100 square feet and each light (S) covers 25 square feet, with 4 lights (N), your total coverage area (C) will be 100 sq ft, perfectly matching your canopy area.
2. Temperature Control Formula (T = (H x F)/R)
T represents the Temperature control effort required to maintain optimal conditions.
H is the Heat output from your grow lights.
F stands for the heat dissipation Factor, which is how well your cooling and ventilation systems remove heat.
R is the Room size and insulation factor, affecting how heat is managed in the space.
Purpose: This formula calculates the effort needed to keep your grow room at the ideal temperature, factoring in the heat produced by your lights, the efficiency of your heat management systems, and the characteristics of your grow space.
Example: If your lights produce a lot of heat (H), but you have effective cooling (high F) in a well-insulated room (small R), your temperature control effort (T) will be lower, making it easier to maintain optimal growing conditions.
3. Distance Formula (D = k x (sqrt P))
D stands for the Distance between your lights and the plants.
k is a constant that adjusts the formula based on specific grow room conditions and plant needs.
P represents the Power output of the light source, in watts.
Purpose: This formula helps you find the ideal distance to place your lights from your plants, ensuring they receive the right amount of light without damage. The constant (k) allows for adjustments based on plant stage, light intensity, and type.
Example: For seedlings needing less intense light (lower P), you'd increase the distance (D) by choosing a higher k value. Conversely, for flowering plants requiring more light, you'd decrease D by selecting a smaller k value.
4. Light Intensity Formula (I = P/D²)
I is the Light Intensity at a given point, measured in lumens or lux.
P stands for the power of the light source.
D is the Distance from the light to the plant.
Purpose: This formula shows how light intensity decreases as the distance (D) from the light source increases. It helps you understand the distribution of light across your grow area, ensuring plants are neither under nor over-lit.
Example: If you move a light twice as far away from the plants (increasing D), the intensity (I) at the plant level drops to a quarter of what it was, emphasizing the need for careful placement of your lights.
5. Light Intensity/Distance Formula (I = (P x k²)/D²)
I again represents Light Intensity.
P is the Power of the light at the source.
k is the constant, as in the Distance Formula, adjusted for specific conditions.
D is the Distance, with the formula now incorporating the constant (k) to adjust for power and distance simultaneously.
Purpose: This advanced formula integrates the constant (k) to fine-tune the light intensity calculation, allowing for precise adjustments based on light power, plant needs, and distance. It's especially useful in scenarios where light power is fixed and cannot be adjusted.
Example: By adjusting k based on your plant's growth stage and the specific power of your lights, you can calculate the ideal light intensity (I) to promote healthy growth without wasting energy.
It appears the the 1st comment on here that's pinned by the cannabis experts explains the formulas. It definitely would've been better if they had just explained it in the video instead of trying to get everyone do some homework
These formulas are very interesting but you dont tell us what the range should be for the answers. What good is knowing those answers if we dont know what they should be?
Just shortly before Christmas in my city the law busted some pretty big crops and a lot of it was destined for my city and the surrounding areas, crops here having the meaning of ganja. This crew had a wider reach than most having a chain of big grows covering a multi city area but they got had by the coppers. So I started getting sick of the steady decline of both the availability and the quality of weed and I took steps and bought a tent and as of tonight in about half an hour I will be ordering either Spiderfarmer, Mars Hydro, Telos, or Omega ĺed lighting aswell as fem seeds. The time for wasting my money is over and the time of growing my own has come I can't be arsed with the headache ffs all I wanna do is get lit and kick back with some nice weed that does what its supposed to do im not asking for the fricking secrets to the universe and im not expecting gold ffs all I wanna do is manage to get stoned and be happy with what I've put in my lungs but you would think im asking for a kidney or a heart transplant.

You need to identify all the letters and what they symbolize
You should watch Dr Bruce Bugbee, if you want to learn something about lights, and growing 🌲
Say theory don't mean sh*t without experience with one short video..🤯🤯..this is mind grinding…any scholarship available??
Wtf, how about jist par levels??
That seriously hurt my brain. lol
All I learned is that I am not a mathematician…
So can someone help me? There is a 400 Watt LED inside the 2×4 tent. How high should the height be?

I have to say Dr. Yates has forget about the Planet rotation, i'm very disapointed 😅😂😅
Huh? Sounds too complicated. I prefer the dispensary.
Didn’t explain the formulas correctly , thanks for trying
I just use, what I have ☺️💚🌿
Thanks for making that clear.
Nonsensical video. Sorry. Zero knowledge was passed here.
I think I just got dumer😅
Would have been nice to include a key for the formula my guy.
Cool 😎
I might be to high for this.
This video was very vague, it would be better to make a video for each formula with examples and applications for each of them.
I have 2 Mars Hydro TS1000 in an AC Infinity 4×4. I learned nothing here.
Only got a 400w light tbh😂😂
