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
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...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.
my 300w cfl is in a reflector and after running for 18+ hours i can still touch it - it's only warm..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.
I know you didn't say for him to get one, I didn't mean what I said to come across that way. I more wasn't sure why that was relevant when it doesn't seem like something he could use effectively in that space. Just curious, what is the actual wattage drawn by the your 300w and how many total watts of CFLs are you running?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...
