Heath Tree Grow Couple of Questions

Hi peeps, I was wondering if someone could answer these couple of questions which iv been struggling to understand, been doing a water farm for a while and wanted to improve it.

To my understanding Heath tree grow consists of recirculating the bottom bucket which i understand, does he pour in the top bucket also at any point, i figured the rockwell would dry up if he is not pouring on the rockwell 3 inches cube, only pouring via second bucket recirculated?

I have set it up exactly the same using 5, only problem is i am not sure if i need a second pump to pour in the top, or just a pump pouring in the second pot, pouring 3 inches above the water level of the second bucket, water level touching top bucket (large holes drilled slightly bigger than pebbles.

Also plan on using a airmaster venturi in a separate tank, apparently there is no other better aeration of a tank, hoping for guidance on that, want lots of small bubbles, apparently this is the dogs nuts.

Been growing for 2 years now, getting half what heath gets on average, with stagnant water, did not use air stones in bottom bucket or tank and poured on the top bucket every 15 minutes (waterfall), total cock up on my part, surprised it worked so well.

Any help would be great, the pdf heath had iv lost and all the bloody decent threads have been wiped, gutted.

Would really like to reel this one in this time. :mrgreen:

Sorry for constant edit, slightly bolloxed
