Just a little more info I'd like to share. the pots are 25l in size and I drilled out 16 2in holes around the pots and 5 in the base, covered with spreader matting to stop the soil coming out. this promotes air pruning which will result in stronger root growth and and overall bigger plant. I have compared my plants veg time to other growers here and they are much bigger so it shows its working. The compost teas are doing wonders and the white mustard plants are great nitrogen fixers and keeping pests at bay. no burning tips so they aren't over fed. I will post am update with pictures this evening.
Day 5:Successful Germination, all tap roots coming out of the blocks so I have prewashed some Biobizz allmix as it's a bit strong in nutes and popped the blocks on top of the pots.
