We drink coffee too but we boil the water in a kettle before we add it to instant coffee, same with tea! Your right, you cant move them at all but can easily see the roots under the cover. 1.2x1.2 is allll most 1.5m2 but with nft you get absoutly explosive growth if you haven't tried it.. do. If you want some ideas give me a shout. You do need them in a tight space when they are mature because they will fall over otherwise. lack of support is the only problem. canna aqua nutes until I went ro (they put chloride in our water here that does not evaporate off also pesticides from the local farm land and lots of estrogen tooo yuk..) Now vitalink max 2 part soft water (very clean nutes MJ specific for ro), and pk 13/14 for 1 week 3/4 strenght as soon as you see the buds spiral, if they have formed a cola its too late. I had a giggle at your "hot hallway" statement! Scaley kettle AND a hot hallway! fucking stroll on! whats he gonna do???? :stoned: We had kettles in canada too. oh yea agro bulbs produce about 430watts each new so we are pdc, yes i put them about 8 inches apart side by side in reflectors not cooltubes. They dont like you growing in germany! have a look at some uk hydro sites, things have really come along way in the last couple of years. oh and the mats i am refering to is like a thin layer of fiberglass before you put the resin on, (i'm guessing you still have surfboards in cali dont ya?!)

Sorry bert, we'z a bit off track here now.

Peace.
