HYDROPONICS COMPARISON GROW WITH 4 DIFFERENT NUTRIENTS
This month we've started a comparison grow featured in our shop grow tent with three different tomatoes, testing out a total of 4 nutrient brands on the market. This includes the following brands:
- Professor's Nutrient (indoors at shop)
- Rock Nutrients (indoors at shop)
- General Hydroponics (indoors at shop)
- Grow Candy (outdoors)
Indoor Lighting in the comparison grow
The light we are using is Hi-Par 315W LEC ballast fitted into a Hi-Par SunStorm Reflector. The Hi-Par 315w LEC Digital Ballast is a state of the art, highly efficient ballast which uses high end components. Combining the Hi Par 315w with the Philips L.E.C 315w lamps gives far greater canopy light penetration than conventional 600w HPS Kits. This is achieved due to the Lamps 92% likeness to the sun. These lamps give a better spectrum and intensity of light, both important factors in a successful garden. If you want higher yields with lower running costs, Hi-Par 315W is the go. We have reverted back to the 315W LEC after a few attempts at trialling a new brand of LED.
The December Brisbane Sun is giving us about 8 hours a day direct on the plants. The plants were planted in Hy-Gen coco on the 7th December 2016 and are fed with Grow Candy nutrient. Photo taken on December 19.
Indoor Comparison Grow
Indoors, the tomatoes are growing in Autopot 12L Single Hydrotrays, with perlite & vermiculite. They are fed with individual reservoirs (20L Black Pails) for each plant. The plants were transplanted on the 9th December 2016. Photos taken on December 19.
