thanks Tevfik..i appreciate the response....i thought a fan was needed also...didn't wanna hurry into it,been reading about "wind burn" from fans,so was a little leary...gonna start that this morning...i been reading alot about "PH" control,as a small grower should i be major concerned about it? i use purified water,and in a month(or less)i'm transplanting to 5 gal. buckets,with all new soils,they should only be in the last stage(buckets) 1-2 months before harvest(right?)Do i need to get a "ph"moniter? i'm not ready to produce"techno-weed(yet)i wanna make sure that i have the basics down pat before i start dumping money into it,(us old timers,on a budget,can't really afford the,500$ light setup,the timers,the monitering systems,expensive wiring,)so we babysit them...AND,i know i said it before,but,is it ...TOPPING before LST...or LST before TOPPING?,you see my plants are only,4-7 inches tall...thanks guys......:smokin:
