A: Rockwool is spun mineral wool fiber. Various "rock" components, with a heavy dose of silicon oxides are melted at high temperature and fibers are formed as molten material is passed by a series of "spinners." The finished product which is "bonded" via proprietary resins, is inert, meaning it has no cation exchange capacity. Approximately 97% v/v/ is air space. Bonded produ…

I started off with 10 seeds (white russians possibly) and tried to start growing them out in the bush.. they did not get enough care and water and stuff and 4 of them died with 5 growing pretty slow and one nearly dead.. after 3 weeks brought them home to put in the garden and they picked up a bit of speed due to more care. They are still pretty small for 5 weeks though but i got them under a 400W HPS globe today. I currently have it on 18/6 and plan on putting them out in the bush in about 6 weeks when the hours get to 14/10 outdoors. Should i gradually bring the light down say half an hour every week or should it be fine to put themstraight out in 14/10 after 18/6 witho…

hey folks, i been around here for many years now, havnt posted alot, but this site has well and truely been the biggest help ive found in every grow ive done. some things had gone bad lately, but im back on my feet and ready to rumble again... i want to achieve 10pound yeild per grow. I was thinking SOG, just for the quick yeilds. And possibly run to waste system. Just for ease of it. I have 11 x 600w HPS light kits, so im hopeing that should be enough. Has anyone out there got any better ideas ? on style of grow or system ? Best ive achieved so far was 5lb off 8 x 600w. 19 plants. not grown SOG. first off, would it be possible to achieve 10p off 11 x 6…

that police choppers sometimes use infrared/heat cameras to find grow rooms inside houses? One of my mates told me when I was telling him about (very) initial plans to maybe start building a grow room, or a small greenhouse or something (which I figure would be safer), and as illegal as it may seem to search a house based on heat measurements (the legality of which due to warrant-less invasion of privacy is also dubious), my mate was very adamant. Anyone else heard/read about this? Care to credit/discredit it?

Hi guys, Just picked up some Nitrosol liquid fertilizer, wondering if anyone had any opinions on this and had used it before? Just going to be a general fert for veg in soil. Regards, U.C

are ten inch pots ok to use when growing from seed to harvest? the reason i ask is my plants seem very small. i normally use 15 inch pots and they have never takin so long to develop. i recentley read you can go as small as 6 inch.

Pretty Some pics from my latest harvest.

Hey just curious does anyone else use the "Turbo Tank" technique. Turbos I have found it to be so easy and efficient. Funny thing is, I have always used a water heater in the reservoir for past grows, but when it broke a couple of months back I didn't replace it. To my amazement however my babies have still blossomed. Well. What effect does keeping the water on the roots at a consistant temperature have? I can understand it is vital in the colder months (especially where I live as the water would freeze) but in summer do I really need to be wasting electricity keeping the water warm? Hmm Thanks
