Monday.... I will carry on dipping just the bottom half of the rockwool block to get the roots coming on...I don't want the roots growing into anything yet as im Air prunning the roots. Which means the root when it hits daylight it will trim and stop growing but further back on that root system it branches off until the next root reaches the edge of the block and so on til the rockwool is full of roots....I I will then put on spreader Matt for the roots to grow into and water once a day... Saturday... Have fim'd these now and Lst them with plant bends. These are not tall growing it says in the write up so I'm going for maximum yeild I can achieve by training them
