   [00:04:35] We’ve spent the last 2 hours prepping the hydroponic system, transplanting the 3” rockwool cubes with the rooted seedlings into the system and backfilling them with pebbles and we’ve evenly spaced them so they’ve all got exactly  the same amount of space to grow in.  We’ve  also   then  employed  the

  prohibitors will stop stuff like pythium and fusillarium wilt and any other type of nasty lurgy that you don’t actually want in your tank or in your root system. So, we’ve used a mixture of House and Garden Grow A and B, and Roots Excelurator and then  we’ve lowered  the  pH  to  the  right level. We’ve then transplanted them, now

propagation domes in order to carry on the propagation process within the pod system itself in order to ensure that we break these plants in gently as I extensively went into previously. Now the tank itself we’ve raised the CF to 14, we’ve lowered the pH to 6, which we believe will be a nice gentle amount of nutrients and the right level of pH to persuade these to break into the system quickly. We’ve also used Roots Excelurator by House and Garden which is known to develop extensive rootballs rather rapidly, it also has all sorts of pathogen prohibitors built into it, pathogen

we’ve set the system, because the roots were emerging and they were good looking, established roots coming through the 3” cubes, we’ve got the system flooding, 1 flood every 3 hours and it’s a ¾ flood and then a ¾ drain if you will. You still end up with an inch of water in the bottom of all these pods and capillary action will work the moisture through the pebbles. It was a built-in safety feature; what we’ve done to utilise it is put an aeration system in the bottom of it, so we’ve got an air compressor wired to a network of air stones built into the bottom, bubbling air in and we’ve got a flood every 3 hours...
