Yeah typical salesman, yeah cfl will work fine, you may have to learn about topping and lst, but for your first grow just get the plant to flower. I use 2 x 85watt cfl, they work well, they have there pros and cons, pros for you will be heat and running costs. HPS are by far better but not always practical and they are expensive to run. I dont think those fans have enough power to pass the air along properly, but they might work fine under cfl. The other option is to use a cool tube, a cool tube "seals" the globes in a tube and air is passed though the tube to keep it cool, expansive though. If you can move over to cfl, 100wats or so per plant is the norm from what I have read.yeah they are computer fans, i think anyway, i got them off amazon as they had USB plugs so i could run them, with the doors to my wardrobe open the temp has gone down to around 38 degrees after about 30 mins, i originally was going to use cfls but the hydro shop guy said to use this, maybe he didnt know the size of box i was useing or didnt understand when i told him, if i was to replace the hps i have for a large cfl would that be enough light for just 1 plant and would that help with the heat issue im having?
Many thanks for the help
Na, the reflector should be fine to use, you can probably attach 2 globes to that, not sure about the fitting, do you know what type it is? Also what purplekush said is right, cfl's don't penetrate the leaves so well, so you would have to be able to adjust the height of the light and learn how to LST, there are threads here on it pretty simple from what I can see. But first get the plant to grow and then we take it from there, remember seedlings under cfl need to be close to the globe, 4 inches or so if I am not mistaken.would the cfl be the same fitting as the hps i have atm? would i just be able to swap out the bulbs or would i need a whole differnt hood thing?
You know that is a really good question, the rule of thumb is get as much light as you can, I think it would work without having to adjust but not for seedlings, they will stretch in that environment I reckon. Besdies it's not all that difficult to make the reflector adjustable, cut the sides off a bit and use easy rollers.he did try and sell me one of the cool tubes when i went in but it was way too big to fit inside my box and needs a fan that would be too loud, i was thinking of maybe purchasing http://www.amazon.co.uk/gp/product/B00D88APME/ref=ox_sc_act_title_1?ie=UTF8&psc=1&smid=A36MGAI5WC5J54 and drilling a hole through the top of the box and feeding a socket through it then i could lower it, is a reflector needed due to the whole box being reflective?
