GREEN MIND SA

Hydroponic crop test report under L.E.D lighting
Our evaluation will aim to determine the gram per watt yield on three grow box crops, for an area of 1.5 m by 1.5 m, or 2.25m2.
Each box contains 49 plants in 7-liter pots on a hydroponic coco substrate.

Open circuit percolation irrigation from the same mineral nutrient solution reservoir.
We will opt for the CRYSTAL TOP fertilization range.
In order not to distort the test, all parameters will be identical on the three boxes.

Details of the cultivation protocol

Genetics and techniques used:
‍
LIMONCELLO CRM phenotype from Green Mind SA, identical in all three growing areas.
49 plants placed in each box, each pot with a capacity of 7l of substrate and a size of 18x18cm.

For the first test, we opted for a hydroponic substrate in COCO. (Plagron)
Irrigation is carried out by open circuit percolation, controlled by a TROLLMASTER AQUA-X cyclic timer, on a cycle of 30 seconds every hour for the daytime periods.
With regard to the night periods, the cycles were set at 3 x 1 min per period of 12 hours of night.
The electro-conductivity levels will be kept higher than on a crop under 1,000w HPS lamps. EC from 1.5 to 1.9 in the vegetative period, going up to 2.9 in flowering without any signs of burning or over-fertilization.

The Ph kept in a range between 5.5 to 6.0.

Course of cultivation
The three growing areas showed distinct signs of evolution on the plants.
‍
The transit, adaptation and rooting period is faster on the model:
600W AIR GROW PRO III HYPER RED
‍
The vegetation period is slightly faster on the models:
F.O.G 600W AIR GROW PRO II and Osram by fluence 660w Spydr x
‍
The stretch over the pre-flowering period is more pronounced on the luminaire:
Osram by fluence 660w Spydr x
‍
For the 3rd, 4th and 5th week of flowering following:
the 3 luminaires are equivalent.
‍
For the last 2 weeks of flowering:
1. The fluence 660w Spydr x lamp, seems to give fruits of a larger caliber but less compact than the F.O.G, the tint is light green and start to turn yellow.
‍
2. The F.O.G 600W AIR GROW PRO III HYPER RED and F.O.G 600W AIR GROW PRO II luminaires brought to the plants, a purple, violet hue and very compact and hard fruits.
‍
The F.O.G AIR GROW PRO III HYPER RED version brought more flavor and terpenes to the fruits.


‍
Conclusion and yield

‍
In 1st position
F.O.G 600W AIR GROW PRO III HYPER REDResult for 600w on 2.25m2  = 808 gr = 1.35 g/w
‍
In 2nd position
F.O.G 600W AIR GROW PRO IIResult for 600w on 2.25m2  = 693 gr = 1.15 g/w
‍
In 3rd position
Osram by fluence Spydr x Results for 660w on 2.25m2 = 733 gr = 1.1 g/w
‍
The F.O.G 600w AIR GROW PRO HYPER RED luminaire was ranked best luminaire of the test by the company Green Mind S.A
Its grams produced/watt consumed yield and the quality of the final product, are unanimous and position it as the best luminaire tested to date.
