When using the plastic glasshouse, best yields were obtained with 5 cm casing thickness and a substrate mass of 60 kg/m2; being the BE and MP they obtained around 32% and 12%, respectively. Nogueira de Andrade et al. (2007) and Kopytowski Filho and Minhoni (2004), also reported BE’s around 30% with similar based materials substrate to the abovementioned study.
