So ive recently decided to start growing some auto flowering bud, this is my first grow so i need as much info as possible!
i agree with the space you have its probably best not to use HPS - some of the new CFL's are really making huge strides - i just got myself a 300w 8u dual spectrum CFL and the lamp is a beast - according to manufac its pushing roughly 18,000 lumens - just remember if you go CFL you need to keep these very close to the bud a couple inches - as long as you have a decent airflow they will be fine
i've just got a couple of auto's from short stuff and they've just popped looking strong already
but what would be the point in him getting a 300w CFL? ...... but I do not understand how one large CFL bulb will do him much good in his space.
But a bulb that size will still give off a fair bit of heat I'm guessing, so at that point wouldn't it be better to use a 150w HPS and save money in energy costs? A 150w HPS generally uses 165w, meaning that 15w is directly lost as heat radiating from the ballast, much of the remaining heat is from having a reflector around the bulb and not having adequate ventilation. This can be easily avoided by using a remote ballast, increasing ventilation, or if necessary hanging the bulb naked. I do not see how a 300w CFL will put out less heat than a smaller HPS. If I missed something or misunderstand something please correct me, this is just how I learned it and am not saying this is 100% fact.
If you actually read what I wrote I never once told him to go buy 1 single 300w cfl - I simply said that I have just got 1 - what i didn't mention was my other cfl globes that are running with this...
my 300w cfl is in a reflector and after running for 18+ hours i can still touch it - it's only warm..
