hi does anyone use the 1meter trays with rockwool slabs and 3inch cubes on top

how many plants do you have in each tray i was going to lay the trays next to each other then do 3 4 3 4 3 4 with 15 trays would that bew ok or to much under 3 600watt lights what kinda pump would i need i was gonna run to waste and lay the trays on and old door with a gutter on onw side i'd use these spuike drippers that u insert in to the slabs

I use 1m trays with 3 plants to a slab. I have six slabs under 2x600w. How big is your growspace? 15 trays sounds a hell of a lot for 3x 600w lights to deal with.

my space is 2.5 x 2m was just gona do them in a row 10 tray is 1.5meteres so 15 should be 2.25m mights add a 600 or get dimond reflectors

can any of you helpful folk point me in the direction of a thread on actually building a diy dripper system?

lots of people here seem to use em and i've seen some really good results (nice one burns!) but searches have got me not very far on building one.

cheers people

anyone help on this? i've read arai's, loveweed's and burn's threads but could do with more help

its simple mate

get some 13mm tubing, some 4mm tubing, 13mm 't' peices, 4mm nipples & drippers.

Make a ring out of the 13mm, connect both ends to a 13mm 'T' piece.

punch holes all around ring, fit the nipples into holes, then add the 4mm piping to these nipples. Then attach the drippers.

connect another peice of pipe from the 13mm t peice to your pump and bobs your uncle.

heres my old dripper system...





or you can make ring square by using 13mm corner peices ('L' peice)
