So, what exactly do you use to measure lighting. Apparently HID lights are the go for growing.. but what If i compared a 600w hps HID.. to say.. 10x 48w CF's.. thats incandescent equiv of 2,400w, yet are only using less than 500w's of power. Thats a hell of alot.. and I have two 48w fluoros on my seedlings at the moment, and they are going just fine.. although the light could be a bit stronger. How can I find out what is stronger than what.. Im thinking of buying a 400w metal halide light second hand for $85, and keeping a few cf's in the growroom. Then, in four weeks at the latest, get a new 600w hps and have the 600hps+400mh in the growroom for a nice flowering stage.. …

Hi, I have to buy a light for my ladies today or 2moro, or very soon anyway. I sprouted them in a glass of frequently changed spring water, and have started them in small rockwool blocks. Some of them have started rooting, and today have started to open out their first set of jagged leaves. Theres two 'sets' on the plant at the moment, so they are still small.. From being sprouted to this stage has taken nearly one week now. But I do notice growth when I go to sleep and wake up, or go out and come back. I water them with lukewarm room temp water, with no chemicals. I have no bud to smoke and just moved to this area, and arent the type to walk around train stations asking …

Hi All, My plants have stretched 300% so I had to move them out of the wardrobe and into the middle of the room . Would ventilation be required if the plants were in the middle of a room with an open window and an oscillating fan blowing 24/7 ? Apart from the stretch the plants are looking excellent, only 5 more weeks to go Cheers dwyndorf

Hi people's. Well i got some reasonably good news,the "terrarium" works in propagating seeds ! I used a; NEC TRI-PHOSPHUR FL 30SSBR-HG-36 T 8 Biolux HG Lamp I put in 36 seeds and 35 sprouted.(Now i got to find spots for them !) i just use this system to get them growing and once they are a couple of inches tall transplant. I start them off by soaking in water for a day or two and wait for the tap-root to pop out,then place them into seedling mix. THEN transplant,once they are big enough. Getting a head start on next years grow. Hope this is beneficial to other growers. Cheers. P.S the only problem i encountered was the proximity too the ligh…

ok well I am trying to get a bit more of a grasp as to how the lighting in a grow room works and is distributed. the bottom line question I have is what happens if you have multiple lights as far as distrabution goes I understand about the maximum coverage area but thats not really a problem I have what I want to do is put two lights in an area that "could" just be covered buy a single light . for the purposes of this post lets just say I was using 1 400w light and one 600watt light positioned how they are in the attached diagram, now would the four plants in the diagram all benifit from having combined light or would I just get uneven growth according the the pl…

wondering what people recomend and use themselfs I am currently in the first week of veg using 19/5 but I was thinking of making it's days a little longer to firstly give the plants more light in a day and secondly I am hoping this could mean I could flower with a 13 or even 14 hour day giving them the longest light period I can without keeping them in veg <~~~ would that work ?
