Master Grower

  • This Candidate has over 25 years of Cannabis Cultivation experience
  • He's a self-taught cannabis horticulturalist specializing in controlled environment, soilless culture; a tinkerer who is fond of designing, building, and experimenting with various equipment configurations and cultural methodologies
  • He has extensive experience using various substrates (perlite, rock wool, hydroton, coconut coir); various lamps (high pressure sodium, metal halide, plasma, T5 fluorescent); and, various feed systems (flood and drain, top feed, aeroponics)
  • Apart from cultivation, he knows how to correctly cure, trim, and package flower for long term shelf life; many growers do not

 

"I place much attention to detail with the view of improving performance and efficiencies. In order to consistently produce superior results, an indoor grower must have the ability to juggle multiple variables and make appropriate adjustments as required by circumstance. I have that ability and the knowledge required for systems design for controlled horticultural environments."

Forthcoming Project
Aeroponic horticulture has much potential to streamline efficiencies. While yield and quality may not improve, some of the advantages are outlined below:

  • First, aeroponic horticulture does not require the purchasing, handling, and disposal of planting substrate nor their associated costs.
  • Second, aeroponic horticulture facilitates early detection of macroscopic pathogens which inhabit the rhizosphere (i.e. root aphids).
  • Third, aeroponically grown plants have shorter internodal spacing as compared with any other cultural method. This feature will increase the ratio of top-grade flower to off grade flower, thereby increasing the crop value of cultivars which have wide internodal spacing.
