I have 120cm x 190cm closet wich I use for cultivating. Got quite nicely working hydro with 800 litres per hour pump and small air pump. I currently have 4 young ladies growing in 18litre pots. Have 10litre upper pot and 18litre lower pot for maxium room for roots. Upper pot is filled with leca-gravel and has little touch of coco-fibers mixed in it for keeping the pots little moisturized. For lighting I got 600w HPS in cooltube and 2 x 200w nurturelite PURple ESL-lights. I'm using also 130cm x 120cm screen its bended slightly from middle to fit in closet properly and also for keeping same distance from hps light on sides too. Believe it or not, this is my first garden ever. Time for few questions. 1. Is it good/bad to keep water flowing through system during night? 2. Got garden going with kinda funny light routine 12/12 ESLs up and 9,5/14,5 HPS up (I'm kinda simulating dawn and dusk.) could this be worth testing? 3. Could someone gimme proper exsample of how much I need to cut leaves off from top of screen/under the screen? Thanks in advance! Isennah, Smoking weed since 1994. p.s. Theres 2 pictures of my current garden in my gallery.
