CFL's are more expensive to run and are actually hotter than a T5.....but we all use what works for us!!

Idealy your girls should be able to touch the glass without getting burnt. the only reason i could think of that the light shouldnt be right ontop of them is if you are actualy in a room and not a little box. then i could see the need to have the lights raised so you can make sure light is getting everywhere.zem said:i'm amazed at how close you put a 1kw without frying plants, anyway why so close? you wouldn't cover enough sq.ft with it being at 6" i would guess...
T5's must be relatively cool then because I veg with these right on top of the plants! How much $$ to set up t5's for my grow? I need about 400 watts...The Hemp Goddess said:Actually, CFLs are the most expensive to operate of all the bulbs we use to grow. CFLs put out about 62 lumens per watt. T5s put out about 92 lumens per watt, about the same as a MH. HPS put out about 100-150 lumens per watt depending on wattage of the bulb. CFLs will also put out more heat than a HPS.

Okay, well I'm sitting right at 7,200 lumens per sq. ft. ... Ladies seem to love it! how much would a set up like yours run? Any ballast and all that needed? IDK much about any lighting other than MH, MV, HPS, and CFL... I guess I know a little about lights!:rofl: What is it like a fluorescent tube? I'm intrigued!The Hemp Goddess said:Yes, they are. I generally do not get burn on my leaves from my T5 unless the leaves grow into the light and actually sit against the bulbs.
Lighting needs are not figured by watts, but rather by lumens per sq ft. For vegging we strive for 3000 lumens per sq ft. So, what are the dimensions of your vegging space? However, like HL, I use a 4' 4 bulb HO T5 that puts out 20,000 lumens in a 4 x 2' space. While this is a little under the 3000 lumens per sq ft, we both get excellent results.

Hick said:.......'actually' the ballast is in the housing/hood/fixture, and they require a t5 fixture.
i.e. you cannot simply buy t5 bulbs and put them in your standard florescent fixture.
All flo's and hid lights require a ballast. cfl's have it built into the bulb.
Gixxerman420 said:The wattage is close to what I'm running now, but I didn't see a lumens rating anywhere in the product description.... Here's the gist... Brand New in Box, 6 Bulb T5 HO Lighting Fixture, 6- 54 watt Bulbs, 324 watts of growing power... It also states that it's 4ft... Long I'm guessing... how wide do you reckon? nevermind... It's 20 in. wide! This is somewhere between 6-7 sq ft. At 92 lumens per watt (thx THG), this equates to something like 4200 lumens per sq. ft.!This would work beautifully for my needs... But the bank is empty right now!:cry: it has a buy it now price of 189.99 and S&H of 29.99... Is $220.00 a good price for this type of system?I can also get an 8 light system the same size with 432 watts for $40 more. Is it a fixed system or could I rig it to raise/lower as needed?(I'm assuming it can be movable, just covering bases)... Any other helpful information about this type of light source that I'm not thinking of here would be appreciated guys! THX A TON!!! Okay wait... I just found a 4' 4 bulb system for $90.00 and free shipping what do you guys think? I probably don't need the 6-8 systems if I'm only vegging 6-10 plants should I? Thanks in advance guys for dealing with my ignorance... I am just trying to soak in as much as I can!
Okay, The 4' 4 bulb system was a used one and has been sold already... I found a new 4' 6 bulb system that is only $190.00 brand new with free shipping.. I'm going to get it just after midnight when the wifey's direct deposit clears:hubba: THX HUNNY!!!:rofl: She doesn't like me growing really (hence why they're in a new place and NOT with me anymore) but she knows I'll be talking about it til' I get it anyways! I love being annoying sometimes! I hate not bringing in money though... Gotta beg and steal to get anything!:cry: oh well... What can you do... Anywayz, the light boasts an incredible 30,000 lumens from 324 watts (about 92.6 lumens per watt)! This is enough to veg ten square feet... And seeing how I'm not growing monsters like yours, (lovely BTW) I think this will be enough... That gives me a sq. ft. for each plant if I do ten... I don't have enough room to flower 10 so I think I'll be good!Roddy said:For $180 shipped, you can get two 4 bulb which is cheaper than the 8 but delivers the same power...nice! I forget how big you plan to grow, but I don't think you'll be vegging 6-10 pants under a 4 bulb, I am currently growing out of room with a mere 3 under my 4 bulb and 4 under the 6 bulb...plants are in 5th week vegging.
The only dumb question is that not asked, my friend!
