OK, THEORETICALLY, under ideal and identical conditions, if u had like 6 identical plants say on there fifth leaves and ready to veg, and put them in seperate rooms under the following lights, no topping etc, how long and what yeild would you expect to get off each.... with me ppl ?? 1 . Under a 48w CF 2 . Under like 200w of Fluro lights 3. Under a 250w HPS 4. Under a 400w HPS 5. Under a 600w HPS 6.

Hi all, Well, after a couple of moderately successful soil grows under 130w spectrum fluoros I've decided to stop mucking about and change to hydro under HPS. My growspace is small (60cm x 70cm x 170cm) and presently has 2 x 120mm extraction fans with passive inlet. I'm wondering whether I should go for a 250 or a 400 watt lamp. Heat may well be a problem for me with the hottest months still in front of us. Yeild is not hugely important as I suspect that even the 250 would be an improvement over my fluoros. What would you more experienced growers suggest. I'd really prefer not to have to up my ventilation as it's already noisier than I'd like. thanks,

G'day All, I thought it might be interesting to see how much lights cost, as in per month, quarter. And how much it varies from state to state. I cant post any information myself as I'm not growing.........yet Please list what sort of light, wattage and state, if possible, and I'm sure it could become an invaluable resource. :thumbsup Oh, and if a similair Topic has already been discussed, sorry for the repetition, and could you please point me.. towards the light.....he he :smoke
