Air 
The device measures temperature and humidity and logs it so you can download the data via a USB connection. Internal memory holds 32,000 records, internal sensors


There are four thermometers in the room, one above, one at the plant canopy, one in the plants and the other at the floor measure temperature at different levels. 

 

 

 


The horizontal bars in the grow tent add structure so the walls do not bow in from negative pressure created by the extractor fan. This is a room full of Kalashnikova under a 600-watt HPS flowering 48 days.

 

 


600-watt HPS + 300-watt LEDs – is optimized with a CO2 generator and analyzer from Ecotechnics. He has found that adding CO2 during vegetative growth increases growth10-20%. At the same time Toni advises that CO2 is the last thing to add to optimize garden production.

 

Sulfur Burner
He turns on the sulfur burner as a preventative measure against diseases and pests with a weekly application during vegetative growth only. Vaporized sulfur lands on foliage killing diseases and pests – botrytis, spider mites and thrips. Remember that sulfur burners have a small cover-age area; the sulfur tends to fall closely to where it was vaporized. Sulfur sublimes (changes from a solid to a gas) between 291-311ºF (144-155ºC). At 320ºF (160ºC) toxic sulfuric acid forms. This is why it is super important to maintain and use quality equipment.

Water and Fertilizer
This is Toni´s base fertilizer and additive schedule. He also adds for experiments with other BioBiz fertilizers at the time of my visits to his garden. Water comes out of the tap with 1,100 ppm of dissolved solids (salts). A reverse osmosis filter is used to purify raw water before adding fertilizer.

Soil mix = Coco-Mix BioBizz + one finger deep of arlita and leave a space at top of container BioBizz AllMix and Light-Mix
