question for the fluorescent growers?

[pass the chicken]

I was wondering if anyone knew what, if any, strains do better under flourescent then others?

[LOC NAR on probation]

sorry none. If you want good bud you have to have good light. Of coarse you can put up 50 to 100 fluro's and get something. Sorry just the truth. I tried many ways.

[Markass]

no, I wouldn't think so..except for smaller phenotypes that will be easier to expose light to all parts of the plant...Get a HID.

[stinkyattic]

Yup, get a HID.
You CAN veg under flouros but flowering under them is a total bitch.
The goal with flouros is to get the plants as close to the light as possible, so a plant that is squat, dense, and bushy will fare better than a tall one with sparse growth.
Go get yerself a HPS though.

[Dr.Hashman]

What about a HO fluorescent light? If he got a 4 bulb Hight Output t5 54w setup, then he could do it. 5000 lumens per bulb=20,000 lumens. 150w HPS has 15,000 lumens, so I guess the 5,000 lumens more could make up for the lack of penatration. He would have to either get an indica strain or mount the light sideways for a sativa. You would have to rotate the thing about every day though :(

[1chronic]

That's an interesting way of thinking about it Dr. Hashman. Plus, you'd just be able to rotate the pants instead of the light wouldn't you?

Eh yeah but ur running 200+ watts with the flouros and 150 with the hps so to hps will have less lumens, i would go with efficiency a 150 is still cheaper to run and u could get a 200 which is like 25,000 lumens, if ur going to compare hids with flouros u need to be on the same watts or lumans page so to say, u cant compare a 150watt hps with 200watts of cfl or flouros, its just not practically,


Now a 200wtt flouro or 200 wtt hps grow, the hps will kill it.

If ur gonna compare lumens, u need the same wattage light. cause then it doesnt really mean much, obvioulsy more watts more power, so a low watt hps and a high watt flouro, obviously we cant compare the 2.

[madeline]

Dr hash, it's all about intensity/lumens. To get the hard, full and large flowers you need the intensity that only comes from the sun and HID's. Flouro's do work but most end up with skinny and fluffy buds instead of the hard nuggets most seek. But as long as you don't mind softer, feathery buds and would rather save a few bucks than put out for "the real deal" then stay with flouro's.

[JackdaWack]

a 400 wtt hps is like what 20 bucks a month to run on 12/12? thats like 80 bucks a grow, so i mean figure out whats worth it, i would rather dish out the extra 40 bucks a grow for like 4X the yield.

[Dr.Hashman]

I am thinking about other things than electricity bills, about heat output. I definitely would use a HID light over a fluoro any day, but the heat of fluoro's is much less than a HID.

[unclebob]

Dr Hashman,

Can't you just vent the heat and run the 12 hr lights only overnight? That's how I dealt with the heat when I had an indoor op in a garage in FL in the summer a few yrs back. Growing indoors sucks without real strong lights. Even 1000s can't compete with the sun, let alone FLs.
good luck either way

[JackdaWack]

i would stongly disagree with the above statement on the sun being better then a 1000's wttr, as i have read the sun has 10,000 lumens per squarefoot, which up to you and how u want to destibute your hid's, so small grow with a 400wtter will do the same in a 4x4 space as the sun. Just a neat fact.

Yeah man get a cool tube and a blower and ur set. a blower alone could work depending on you space. i dont use vented hoods and my heat has always been ok even in a 4x2 space with 6 foot head room and i didnt exactly duct propperlly

[unclebob]

400 watt equal to the sun in 4X4 space? WTF?
I don't know what exactly the lumens per sq ft of the sun is. I think it probably depends on where you are in relation to the equator. I can tell you this for sure though: Anyone who has grown under a 400 and then grown outside in the SE can tell you there is absolutely no comparison. I could have been wrong about the 1000 though. The highest I ever tried was a 400 halide and a 250 HPS under the same reflector and the outdoor sun completely blows it away.
