@420autoflower another couple of quick questions m8 if you don't mind.. I assume they're on 2 floods per day now?? Do you flood your tray only during lights on? Lots of 'info' suggests only flood during lights on? Would your plants ever need to go to 3 floods per day? How far 'up' the blocks do you flood?? If that makes sense.. like on these girls.. would you flood higher than the slab and into the block or maybe only part way up the slab?? Wow.. only had 2 questions when I started typing there.. mind u I'd only just put out a smashing Lecter doob hahaha anyway.. I digress.. appreciate your assistance as always
