Cannabis Grow Rooms

Im growing indoors for the first time and ive put my faith in these lights http://cgi.ebay.com.au/2-FLURO-LAMPS-REFLE...8QQcmdZViewItem The claim is that these lights are different from normal fluoros of the past in that 100W power is equivalent to 400W. Has anyone used these lights? If so did you get good results? Ive been growing Hindu Kush under them for a few weeks and so far its good but they are still young.

High people? Has anyone had any experiance with desel or petrol generaters to power there lights? I have had a bit of a look around the web but camt find a lot on the subject. With some sound proofing and venting i cant see why they wouldnt work. Any comments?

Hey guys Im not sure if anyone has any ideas for my problem... Im setting up an underground (cellar) grow and have all the gear ready to go. I realise one of the most important factors in a grow is fresh air. The problem i have is that i dont want to spend considerable dollars and risk potential damage to my house by getting air from outside down into my cellar and back out again. Obviously through two ducts. I have been researching the internet and have noticed a few growers using sealed rooms with air conditioning and CO2 generators to cool and replenish the air. Has anyone used this successfully? What is the best gear for this situation? My room is 3.5m x 4m …

As the topic says, I have the light and shade now for the wardrobe (180x75x50) and now want to try and squeeze in a good ventilation system in there but there's not a whole lot of room!! (note to self - get bigger wardrobe next time ). Any ideas on how to rig this up? Cheers

Can anyone out there give me some advice. I recently spent $800 on cool tube set up for 2 x 600w but I have not seen any difference in temps. It is quite chilly here today( 21C), but temps in room are 31.5C and that's about what is was without the tubes last year. There is warm air being extracted as when I touch the outside of the exhaust duct it is warm. The fans are from fantech, noisy as buggery, supposed to pump 210 litres per second. Each light has its own tube, fan, ducting etc. I don't know what info to give you to get advice, so you can fire away with questions.... any help appreciated aussie1

if so join in this topic ill keep it running for a while unless no one posts then ill just be lonely so here goes just to give everyone a overview of what we are going to be talking about A plasmon is basically just an oscillation of the conduction electrons in a metal. http://upload.wikimedia.org/math/9/8/6/986...83374eeb46b.png is the basic formula thats used basically or im stupid and dont know what im talking about we could in theory make a shell of metamaterials that could bend electromagnetic radiation around its central cavity so it would be invisible to the human eye the effency of light emmiting dioids in great but we can make …

G'day! I just went to the markets where I bought 2 second hand horticultural lights. For $60, I got 2 x SuperNova 600 reflector hoods, 2 x 400W MH ballasts, and 1 x 400W HPS ballast. Now I'm a bit of a newbie when it comes to these lighting systems (I have only previously used compact fluros with pretty crap results), so I was hoping some more knowledgeable people here would be able to please help me out. Are these reflectors compatible with the ballasts? They are called SuperNova 600 so I assumed that meant 600W (the bulb socket says 1500W 600V) but the ballasts are all 400W. If not, what kind of ballasts should I buy to match the reflector? If they are compat…

Hi all I was wondering if it is possible to do a complete grow from veg to flower with a Spectrum 130W CFL? My local hydro guy usually knows his shit and has never lead me astray before and he said he tested one in an area of H:120cm x W:90cm x D:45cm, with 2 nice plants with great results. He used the 6400k bulb. Due to current living arrangements, this size area is all i'm going to have to work with. I have been using a 400W HPS for many years now and is perfect for my usual grow area, and as much as I would like to use it again, I don't want to burn down my new temporary home. Any help would be appreciated.
