Steering WC & EC at the start of the cultivation
Managing the root begins from the start of the cultivation. Do not underestimate the importance of cutting the drain holes, it’s a mundane task but once cut they cannot be uncut, so do it correctly first time. Having a plan from the start and knowing the lower limits for WC% for your chosen slab type and upper limits for EC of your crop will help you make informed decisions during the ‘steering phase’ of the cultivation.
