Comparison of Peat–Perlite-based and Peat–Biochar-based Substrates with Varying Rates of Calcium Silicate on Growth and Cannabinoid Production of Cannabis sativa ‘BaOx’

Growers have been searching for alternative horticultural growing media components because of their desire to use sustainable resources. Biochar is a carbon-based material that has evaluated as an aggregate in peat-based soilless substrates. Additionally, silicon (Si) examined beneficial element promote plant growth and quality variety crops. However, there limited research regarding the interaction biochar Si This study aimed determine impact on nutrient uptake greenhouse-cultivated hemp ( Cannabis sativa L.). Hemp plants were grown one 12 different substrate blends: with two rates calcium silicate (CaSiO 3 ), types (medium or coarse) perlite, percentages 85% peat + 15% 70% 30% aggregate. The cannabinoid concentration, height, diameter, total biomass similar across all blends after weeks growth. CaSiO amendment increased foliar concentrations, addition mixes did not limit availability uptake. amendments biomass. suggests tested during this suitable substrates C. ‘BaOx’ production at up (by volume) amendments.
