verry nice n clean. how far away are the lights from the plants? they look like you can go closer which will produce much shorter compact plants but they look like there doing verry well without the lights being closer, as i dont know the lights, best wait for comfermation on the distance from plants.
keep it up, growing is the easy part mind you, its when it comes to flowering that the problems realy start, but as long as you keep it clean, change res nutes offten and keep a close eye on them for any problems that may occur, you should be good. keep it up gogo
