What's up everyone. i wandering how much coverage a 18"x48" t5 light fixture will have. i am planning on getting
a grow tent so the inside will be completely reflective. i know a lot of people are against using t5 lights but i am
trying spectrum lighting instead of intensity lighting. i plan on keeping the light close too the plants so that they get
the light/spectrum that they require. the fixture is also reflective. any idea on how much area i will get out of it?

Take a look here. It is accompanied by some readingbut is well worth the knowledge and excitement that follows. ..

Your light will cover about the same dimensions since you are wanting PAR T5.


Look into this thread basically its achieved the quality of led with out led. Using aqaurium lighting we has achieved PAR T5 growing to allow the plant to work more efficiently during photosynthesis. Using the right spectrums and not wasting energy on "unusable light."

Also look into scrogging. Don't be intimidated by it of you are new you will learn alot and be very greatful in the end. The PAR T5 group takes pride in its work.

Scrog them bad girls into some chicken wire or somethin and bam perfect T5 results as long as you keep undergrowth and leaves trimmed.

yep,yep all the above this guy knows what hes talking about and undercovercop(another user) knows his shit. i recommend doing what the guy(hyroot) in the other thread was talking about(coral bulbs and what not) with the t5 fixture. you can probably cover a 4x2x3-4x3x4 area.

scrog definitely seems like the best choice. i have been looking into it for some time now. that thread was what gave me the idea for the t5's. great thread.

so t5's are only good for the size of the fixture? would a plant receive enough of the right spectrums if the fixture only covers half of the plant; or a quarter of the plant?

well you can go outside the boundary a little but you wont get the growth that a plant fully immersed in light would. you can out of the boundarys a little more in veg because plants have less to focus on and smaller thus requiring less lumens. scrog and t5 go hand and hand. just like vertical and a cooltube or LSt and an adjust a wing lol

If you have questions on bulb selection. I would honestly read the thread as much as possible. Go into general settings and change the number of posts per page to 40. That way you can scroll through and skim the necessary information.


What do you know so far about the proper spectrums and each their respected use?


You are gonna need to learn about PAR AND PUR.

About.com has some great information on the two subjects and how they relate to us for photosynthesis.
Here is a link for some useful info on the two. . .
http://saltaquarium.about.com/od/lightslightingsetups/ss/The-Importance-Of-The-Par-Pur-Of-Your-Reef-Lights.htm

The power Bands are from 420nM - 550nM and then pick back up at 630nM - 660nM

It's going to be best if you balance the spectrums. The close to perfect PAR set up would be 2x 420nM super actinic 2x 650nM roseate 2x 12000k actinics (has some green to facilitate photosynthesis) and then depending in what stage you are in 2x KZ FIJI PURPLE 440nM and 660nM.
Or grow bulbs for veg.

I think this would give you the best balance with still supporting the green requirement.

what about his uv when he is flower? my bad this may seem stupid but im a newb too when it come too t5 bulbs and equip. i just got into them and am starting my research.

i agree 100% the onlt difference i would make is using 1 reptisun t5 10.0 in place of one of the actinics

should be ok with a 2x4 tent... id think about running two of those 4 lamp 4 foot t-5s in there ether two on the top or one up top one on the back wall...you could just rotate ur plants every other day or so...i used to grow that way under bunches of t-8s when i first started. the rate of growth and flowering will be a lil slower with t-5s compared to HID but you should come threw with quality crops in the end.

Hey i have a t5 2'x4 bulb 6500K fixture.

How far can it be expected to provide for 2 seedlings?:confused:

plays a major role in resin production...

Because it stimulates the plant in a manner of speaking that is almost like a sun burn. It reacts to it in a way that damages cell tissue then it rebuilds stronger and in doing so produces more resin as a by product of the energy made while repairing the cell damage done by the UVA rays. UVA should only be used in bursts IMHO

uva is very weak it is too close to visible light and plants are already built to resist. uvb is where its at and only during flower i dont agree at all with bursts i fun 2 26w cfl 11 hours with my 12/12 in a 4x2x4. the key is the proper amount of uv and the distance. plus the rating of these fluoro in comparison to natural sunlight is like 1/10 the actual strength of the uv in where cannabis grow naturally.

this is why i run uv all day. it good for them and makes em stronger and will barly slow down anything if properly used and the reward from uv all day is worth it.

but hey where not here to argue about Uv anyways dude stick with this guys bulb plan and play around with uv later

Two daylight tubes will do your seedlings about two months. Eventually they will need 360w of daylight tubes to keep on greening. they'll be like 6-7' tall by then. All t5's are standard 4' unless otherwise noted.
