GVGO Seminar Update > Tips to a bigger plant by June 15th
1. If growing in a hoop house supplement in the predawn hours of the early morning with some type of CO2. raise ppm up to 1200 and watch results...At seedling stage, CO2 concentrations in hoop houses can be higher than that of outside, due to the vigorous soil respiration and lower canopy size & photosynthetic rate. However beginning at multi leaf stage, severe CO2 depletion will begin to occur because of stronger canopy photosynthesis....Remedy is to ventilate by adding sources of CO2....
