Bonzo your system looks so great you have inspired me to build somthing simular when I get some free time and my Nirvana-Papaya strain going :wink: But what I have in mind is same thing your doing but with Perlite insted of clay like you have done and setting it up on a watering cycle of about 15 minutes a day 8 times a day with gravity return feed . Was going to use clay but iam told perlite heaps better for devolping root systems as it doz'nt retain as much moister as clay and the motion of a quick draing medium like perlite draws more oxgen to the root system . Iam going to call my setup the Bonzo bucket
