OK I'm looking for a light that I can veg around 6-10 plants with and I cant decide between the 4 tube t5 lightwave and the power plant 250w cfl so any advice on which would be the best for a small vegging tent would be great :peace:

i would defintely go with the t5s, i've ran both and the t5s definitely work better mate, you have to run a lot of cfls to match the area covered by that t5

I would prefer the t5 but I just want to make sure it's the best option. on the net its says the t5 is 96 watts but 6'600 lumens i' not sure what the cfl is thou

I found this on the net about the power plant cfl but I'm not sure if its accurate--

PowerPlant Envirogrow CFL
PowerPlants Self Ballast CFL Lamps. Now avavilable in 300w. Super Cool White for propagation, Cool White for growing and Warm White for flowering. 150w with output of 9000 lumens, 250w output 15000 lumens and the new 300w with 16750 lumens. All with an average life of 10000 hours. Also available in kits with the PowerPlant Sunmate CFL Shade single lamp or twin lamp.

id go with the numbers, i use a 160w dual spec enviro cfl in my mother tent 80 x 80 x 160 that does me fine :)


You're going to want at least 3,000 to 5,000 lumens per square foot during the vegetative period.

4 x T5 HO 24 Watt tubes will give about 7,600 lumens (and use about 100 Watts), which is about 760 lumens/foot².
250 Watt compact will probably give around 19,000 lumens, which is about 1,900 lumens/square foot. :)

As a Journeyman Wireman, I can safely say, that although it may be a cunthair more expensive to run the T5's(which shouldn't even be noticable), you will get a greater coverage than with CFL's, unless you run a few of those 250W equiv's you are talking about, but one can NEVER go wrong with spending probably the same amount of money on say, a 400W MH and veg the living shit outta your 5-6 plant grow, which I surmise is probably in a smaller apace like a closet or something... With a nice coat of flat white paint, and 5-gal buckets over a short drain-pan and grate, with a sm. sub pump for drainage, plumbed into a 5-gallon "office-style" water jug, I run a 400W MH and a 250W MH along with 2-250W HPS in a 4' X 2' closet and can easily illuminate and bathe anywhere from 5-11(right now) nice plants in intense H.I.D. lighting, coupled with a cheap-to-operate little home-made CO2 gen, and some good fans, and I regularly crank out .91 grams per watt on my 1,150W mixed spectrum system... I'd definately always run the numbers, and as long as you can control your heat and ventilation, and it's not going to double your electric bill, then, I'd reccommend doubling, or tripling, in my case the suggested amount of lumens per sq ft, and watch the bounty... But, you haveta be careful and watch your stretch, as it can become overwhelming if you do not prepare accordingly, with lights that are easily raised or lowered at any time, stakes, a trelis system, or ScrOG or SOG type ststem...which is oftentimes very necessary, especially if you FIM, and/or super-crop, as I do...

t-5s are the way to go more lumes per watt..but clones under an MH will grow and root way quicker.

t5 for sure, those cfls are great for growin one plant with one of them, but for a room of 6 deff t5

Sorry but this isn't quite accurate. Light diminishes as it travels so the plants directly below the CFL will receive ~3klumen and the plants on the outskirts will receive practically nothing - way below 500. T5 will work much better as it evenly distributes the lights so all plants get their share. This isn't to mention flouros peak efficiency between 50-70w so 150w+ cfls are fairly inefficient.

If cost is an issue go with CFLs but buy the cheap 23watters which can be found for $0.50 a piece. They are more efficient than the large bulbs and many smaller bulbs allow you to evenly distribute your light. I would recommend pairing the 23watters with a cheap bathroom vanity light ($3):



And to not seem biased I grow with HIDs, tube flouros, small CFLs, and also have two of the big 250w CFLs in refelctors. Guess which ones I always have benched?

I will never use these again for veg. Most likely just never again. 500w and the plants on the edges were receiving practically no light.



I do still use small CFLs for veg though and they work wonders! Like others have mentioned MHs work amazingly as well.

can you please tell me where you get cfl's for $0.50 each, and those vanity lights for $3? i would love to know

fuck the lumens and all that jazz. lets hypothetically assume the lumens are equal. the cfl might be cheaper but the t5 spreads the light over a larger area and it spreads it evenly. it makes it a lot easier to just train for an even canopy and use all that space and get as much plant as you can under direct light. the cfl distributes the light the way an hid does but without the penetration. you will never get as much plant under the "sweet spot" of that cfl as you will under the whole t5 unit, where everywhere is a sweet spot.

if the cost is not the primary concern i would go with the t5.
