I use two of what Duck's using in my 4x4 to veg.

Sun Blaze 4' 4 bulb T5HO Fixtures. I would do two fixtures even in a 4x4 over 1 fixture, for more ability to adjust different level canopy's for veggin' stuff. :)

one thing i noticed with 4 ft fixtures is that the light itself is 4ft, and the sides of the fixtures add at least 2", and then to move it easily up and down i would make the space at least 4'+4"

I'm confused by this. Not sure what you're worried about but the 4' fixtures fit wonderfully into a 4' tent, with a few inches on each end before the walls. :aok:

Here's an example:



Maybe I'm confused by what you said Zem?

I think mine are Hydrafarm.

My 4 bulb fits nicely in my 2x4 tent.

Check the dimensions, not all 4' lights are over 4'. Mine is 47" total. I got it from HTG supply a lot of years ago. I do not believe that you necessarily need to buy a real expensive one. I bought about the bottom of the line model since I wasn't sure that I could actually replace a MH with a T5. Mine did not cost much and I have used it continually for almost 7 years--looking at some old attachments I had, I saw that I bought my first one in May of 2008.

I would say that 2 of the 4 tube fixtures would be enough light or maybe a single 8 fixture unit. Like duck, I have a 4 x 2 vegging space and (generally) use a 4' 4 tube fixture in there.

Ok thank you all very much!! I believe I will go with a 4' 8 bulb system .. Is there any places online that ship everything discreetly? Some of the stuff I'm going to order from Amazon isn't gift wrapable, Or doesn't it matter because the FedEx people couldn't care less?

Just mentioning this one more time, just in case you didn't read before..

My thoughts: Instead of 1 big 8 bulb system, get two 4 bulb systems. Exact same amount of lumens, but say you have a bunch of 5" clones rooted and ready to veg, and you also have some plants 3-6 weeks vegged out. You will want one height set for the stuff that is double in size, and a different height for the smaller stuff. Now, you can fix this by bringing the plant to the light instead of the light to the plant, but if you're in my situation and your veg system is a flood and drain table, you want to be able to precisely adjust different zones of lighting since I can not bring the plants up to the lights with this setup. Also, if one fixture dies (for some strange reason, as T5's don't seem to die) you will have 1 fixture to raise and at least get by until you sort your second fixture.

Same amount of light. Same price. More versatility. Just my thoughts there, obviously an 8 bulb fixture is sweet, just wanted you to consider two fixtures first. :D

lol you're welcome :aok:

Honestly, it just makes sense to have the ability for a more versatile light foot print, so wanted to toss that your way one more time. If you were soil only, it's no real problem only having the one light, as you can raise plants to even out the canopy, but it's a bit harder to do in hydro. Maybe easy enough with 5 gals, but not with my 18 gal totes!! lol :)

Glad you have a Dr. you like :D

Indeed. I have 2 pulleys on each of the T5's, so you can even drop one end and raise the other for "stadium seating" style hah :)

Thats a good idea Fang.
Cheers WH :aok:

That tray on top of an electrical fixture? I hate to sound like yo mama here, Doc but that looks scary to me.

Not scary at all :) There's no water in it, and the cuttings LOVE the extra heat this time of year! :D
