i am going to use a 4x4 x 7ft tent . but have never used hps before n want to use 800watt bulb to be very productive . i was wondering what cfm i would need to pull through a carbon filter and cool the room/bulb or what should be done i have not used a hid before but a quantum t5 . so any info will help alot.
What your gonna want to do is get two fans. One to vent the heat from your light through an vented reflector a 4-6" Inline fan approximatly 170-424 CFM should work, and another 4" 170 CFM inline on a carbon scrubber to vent the smell. Your tent should come with pre-cut passive intakes. I grow in tents and this is the best way I know to accurately control the environment. Otherwise they become a big ass easy bake ovens. PM me if you need any other help.
starting one myself wanted to know about these 100w fluro grow lights are they any good? they claim to be as strong as a 400w hps. is this true...? was gonna use for the veg cycle. 1 x 100w red spec and 1 x 100w blue spec. and then a 600w hps and 100 w red spec fluro for flower. what ya rekon? any help much appreciated.
I doubt any flouro will ever be as strong as an HPS. No way a 100W flouro can match a 400 w HPS. Your lighting setup sounds fine to me. It's about par lumens more than wattage. Tell me what the output rating for the floro bulbs is and I will tell you if you have enough.
i have a quantum t5 8 lamp and it is awesome . compared to cfl. hps i have never used but will in the future i think when the time is right. if you are just veging with it people love t5 's it is so much easyier than all the hassle of cfl fixtures
Ok sweet. i was pretty sure the fluros didnt match up n watts like that. i havent purchased a fluro as yet i am looking into them . what is everyone take on them? am i better o using a whole heap of tubes or should i go get one of the proper fluro/reflector sets. what should i be looking for in the fluros when i purchase. thanks again in advance guys much appreciated.
if you go t5 it is good for say 4ft 8 lamp for 4 plants. they now have bulbs that put out 11,ooo lumens a bulb for the flouros that keep it in close proximity of the hps . hps are still better but t5 will still have good quality. there is a 8 lamp t5 that you can get for 125 $ and one for 199. to start is not bad pricing if you go for the hps you will have to spend a bit more . also you will need good ventilation for sure.
I am using a 4"x4"x8" grow tent and I was told to do 600w max with a cool tube and 424 cfm fan(vortex fan) there 100$ and you can make your self a cool tube really easy if you go to DIY threads if you are on a budget. And the carbon filter you can make for cheap too or you can buy one for 80$ for the tent
------------------ thanks i'll have to check that thread out . i have been chacking around and have found some cool stuff good prices . trying to put it all together. but first i want to play with my badboy.
