The T5 Light Wave help needed

charlesweedmore · Feb 6, 2009

i am going to buy 3' X 3' tent for keeping 7-8 moms under vegging all the time and making my clones and vegging my seedlings
(i have 5' X 5' sqft flowering room already )

i will buy 250 or 400 watt MH lamp some day,but now i should buy Fluorescent T5 for the vegging moms and clones.
i know only thing that i should buy 6500kFluorescent.
that is all..

but i dont know how many Fluorescents and how many watts should i buy for keeping 7-8 moms at vegging stage all the time and rooting and growing my new clones..
the brand is important ?

in addition,should i buy T5 or T8 and which is better ?i dont know anything about Fluorescents..

what is your opinions ?

i will keep my seedling under these Fluorescents for first 10-15 days untill they would be rooted and after 10-15 days,they will go under 600 watt hps to keep on vegging..

i read '' the powerful lamp is not good for rooting clones and new seedlings .the best option is flouro for them ''

therefore,
even if i have got a mh ,i will also have to buy flouro for young plants.
if i havent got Mh,i will have to buy flouro for young plants.

as the result,flouro must be bought for rooting clones and seedlings to achieve the best result.
In addition,i know that min 3000k lumen is provided for per sqft..

but i dont understand that point..
i found lots of T5 sets but none of them provide 3000 lumen for per sqft.

for example,look at this :

The T5 Light Wave is supplied with 6500k 54w cool daylight tubes and tests have shown that they make an excellent substitute for metal halide lamps giving great performance and saving power when used in the vegetative growth stage. By adding red lamps they can also be used to good effect in the flowing stage. The T5 Light Wave can be suspended horizontally or vertically making them good as either a main or a supplementary lighting system. To see them in action check the article in the resource section of our site.

• Low running costs
• Low heat
• Superb performance
• Can be suspended vertically or horizontally
• 8 tube version can be used as a 4 tube with a click of a switch
• Supplied with Cool daylight tubes (red tubes available separately)
• 17800 lumens
• L= 1200mm W= 350mm D=60mm

1200 X 350mm =4.8' X 1.4 ' = 6.72 sqft.
total lumen : 17800
17800/6.72 = 2648 lumens for per sqft.

Or;

Fixture for 4 x 18 Watt fluorescent tubes à 60cm. Ideal for propagation or small grow rooms.ca. 65 x 70 cm.
A power cord is needed.

but 65 X 70cm = 2,6ft X2,8 ft =7,28 sqft.. 10000/7,68 =1.3k for every sqft.
isnt it very low for rooting clones and new seedlings ?
i will also use this for keeping 8 moms always vegging ..
what is your idea ?

does it mean that this is useless ?

i need your helps,thanks
