General Cultivation Q&A

So I am looking to put together one of these PPK systems popular on icmag at the moment and am looking to avoid the issues inherent in coco(bugs mainly) so is there anything out there that will work like what the yanks use known as Turface which is just calcined clay in the right sizing to be good for a growing media as far as the reading I have done has told me. Only thing I can think of that is similar is clay kitty litter but fuck that shit is 80% dust.

setting up my new tent 1m square 2m high with the carbon filter 6" the inlet fan is a 4" inch which thinking about buying combo is this fan set up good i was reading about negative pressure inside tent will this combo be enough or do i go to 6" for both inlet and outlet thanks boarderliner

For those of you who maybe interested I received an email this morning offering a course in Cannabis as medicine. I am in no way affiliated with Green Flower but am merely a member who receives their newsletters and thought others here may like to investigate. Admittedly there is a cost being $197US or $261AUS, but for those who want the info it maybe a valuable resource.

Hi guys Is it ok to used a small battery power airpump for a small amount of time i have two home made 40 liter dwc will this be enough to keep plants going for a short time if there is a blackout i think it will but any advice is welcome thanks boarderliner.

ok..so I poked my head in the room to check if the lights were on yet and saw that at some point ive left the normal light globe room light on meaning that during the 12 hour lights off period the girls have had the glow of a small light globe on instead of complete darkness...there only two weeks in and are still showing some little pre-flowers...they seem to have stretched more than usual but my question is....should i leave them in complete darkness for 24 hours to try and make up for lost dark periods or just keep the usuall 12/12 going...any suggestions? p.s im not too concerned about them going hermi or back to veg as little flowers are looking normal.

hi guys has anyone use led and cfl lights together i been doing a bit of studys on different light spectrum on internet . with the cfl light you can get red 2700k for flowering and 6400k blue for veggy . Can i used the red light spectrum for a little while during night cycle to increase flowing size and faster time to havarst thanks boarderliner

Hello again i using a led clf combo when the plant is in veg cycle can i use blue spectrum light in day cycle with led and when i start the flower stage can i use red spectrum with led or one blue one red with led all the time though both cycles thanks boarderliner .

hey guys and gals, its my first time using this "rock" product called "burst" ...its about a week and half into flower and so far it seems to have just increased stretch and internode length and ammount. Im just really hoping the stretch stops..I will know by the end of the week but basically just seeing if anyone out there has used it before..it says on the back of it that it creates a "reproductive flurry" and to use it for the first four weeks of flower..so if anyone has used this before let me know what to expaet and if its effective...also ive noticed white little growths on the upper stems of some of the bigger buds..im sure its not mites or anything as some og them…
