Hi all
I'm looking for some advice from experienced growers with regards to the size of light, heat generated and the right exhaust fan to deal with that heat in a closet grow.
Ok let me give you the grow breakdown and info first.
Clost floor square feet equals 4.59 square feet or 1.39 square meters.
Height is 198cm or 6.49 feet - plants will hit the light anything above 178cm
I'm vegging in a box i built with 9000 lumens cfl, going well, so the closet area is going to be used just for flowering and possible final stages of veg)
Initially i thought a 400 watt hps sunmaster would be ideal for flowering at maximum yield in that space. But after reading up about par watts and lumens and what the plant needs for optimum growth i realise that i might be wrong for the grow dimensions i have.
Over 5000 lumens sq. ft./53750 lumens sq. m. = Optimal growth. Dense growth in all stages. (rough rider thread 2007) http://boards.cannabis.com/indoor-lighting/140735-answers-about-cfl-hps-how-much-light.html - is this correct ? homepage for sunmaster is very confusing with their 400 watt hps lumen outputs as they seem to be a lot lower (35000) then the 55000 lumen that grow shops seem to quote.
Ok so this essentially is the info i'm looking for. I'm going to be dropping money on this setup and want to do it right. The extraction fan i'm looking at is the TD Silent 500/150 Inline Fan - Volume flow: 580 / 430 m3/h - id like to know if it could handle heat build up from a 600 watt hps sunmaster in that small space or is it light overkill - am i better off with the 400 watt hps or 400/600 metal halide which i believe produces more par watts that the plant can actually use in photosynthesis, yet most swear by hps for flower ??? It can be very confusing.
The bulb will be in a pebble arc hood un-cooled. I will have 2 or 3 small computer fans moving air about in the closet.
I'm looking at 4 plants in a organic soil grow with single cut to bush and LST training. Bio Bizz nutrient feeding scheme throughout.
If someone could confirm on veg height before going into flower sos i dont end up hitting the light that would be great :) 90cm veg = 5 foot plants end of flowering, plants will hit the light anything above 178cm or 5.8ft.
I would like to order final bits and pieces for grow and your comments will help to guide me on a super grow vs average grow. If there is any more info needed please ask. thanks a mill.
Much love to the community
Peace
