PH OF SOIL = 6.6/6.7 (Taken with a ph tester)

Not using any extra nutes yet (just normal soil)

Its about an inch away from the bulb

and the spec of the bulb is 20W

also im basiclly just using the bulb thats the normal one for the room (hence the high cabinet) and am unable to use more than one bulb in the one socket.
