New Wave T5 Grow...IM NOW A BELIEVER !!

[D Rock]

Otherwise...doesn't really compare to the lumen-generating and canopy-penetrating power of an HPS light.

thats why we growers use LST. Maybe I sould do this with my plants altough it might be tough using grow bags, hmmm Im going to have to think of how to LSt with bags instead of a pot. Any ideas?

I personally think they rock!

Below is the product of a T5 (4 - 4 ft.) grow. 6 weeks of veg under 4-6500K "cool white" bulbs and currently under 4-3000K "warm red" bulbs. The photo was taken 18-19 days into flowering.

The strain is G13 x Diesel.

2 gallon pots (going to switch to 5 gallon in a few days).

All Fox Farm products: Ocean Forest soil (started seeds in Light Warrior); Grow Big, Big Bloom and Tiger Bloom nutes.

I keep the lights no farther than 5 in. from the tops at all times, and the lights are so cool that I never worry about or have had any problems with burning.

I've heard about diminished yield with T5s but so far everything looks good... but we'll see.

Does the 40,000 lumen equal more than the 53.000 lumens of a 430 watt hps if the distance from the plant is decreased? Isn't there an inverse square law on light penetration? Legitimate questions as I am not sure, been a long time since in physics class.

My understanding of the measurement of lumens is that a lumen is how much light the source gives off to a point that is one foot away. So 53,000 lumens would be the amount of light a plant gets when the light source is one foot away. So if the source is two feet away, then the plant only gets 1/2 that amount or 26,500 lumens.

Conversely, bringing the light closer, say 2 in. away from the top of the plant, would increase the amount of lumens the plant receives. Can someone confirm/refute this as I'm not entirely positive of the latter portion of this post?

Well I will throw in my 2 cents...

I use T5s for veg and I will use nothing else. Some growers that I talk to say that T5s will not promote a hearty enough plant but I think that this is not true!

Plants love T5's! They veg fast and get strong for a fraction of the wattage. I use 2 4' long Sunblaze44 T5 arrays. The reduced heat is the biggest plus and you can spray your plants with almost any fungicide/pesticide/inocculant without any burn!

I do believe however that yields are reduced when flowering under T5. The lumens are just not enough and the light diffuses to quickly especially if you are trying to penetrate a deep canopy.

I have 2 flower rooms. One has 4 X 400 watt HPMH full spectrum bulbs and the other has 3 X 600 watt HPS using Hortilux's Super HPS bulbs. I love them both because they each have a lot of upside. Ultimately I want to get both rooms to 4 X 600 watt Super HPS lights. T5's can't touch that!!!!!

I too like the T5 setup for veg. Currently i use 2 - 105watt 6500K CFL's for my vegging. I have a small Med garden so I only flower with a 430 watt hortilux hps. I would like to go to a 400 watt T5 for veg and a 600 watt hortilux for flower, someday when I have a little extra scratch.

I flower and Veg with my T5 and get great results. I have a mixed spectrum 4 x2 ft.

I was extreamly impressed wth my results, Gotta love the No heat factor. It works well in my Box.

There are 2 kinds of T5 tubes.One is like the oldfashioned,just stronger(and thinner),kind of HO.Then there is "Compact T5 tubes"
These are double and on 55 watt each.One unit usually consists of 2 or 4 compact double T5´s.THESE are the ones to buy.Today they can be bought for the price of an oldfashioned tube some time ago.
Usually they are in a mixed spectrum too.One doubletube is cool white,and the other cold white.
But the other T5´s are absolutely also good to use.It has become more easy and cheap to light da ladies.!:rasta:
The picture is one of my Cinderella 99.Have been in flower 3 weeks today.

wheres the next post? or is this it?

[markyola]

yup all 3000k warm and i dont grow to sell...i just look at it as Im saving myself this money by not going out to buy...so what better to invest the $$ in a good efficient grow light!!
================================================== ==============
i have a 8 4ft ho t5 setup.. i have 4 3k warm and 4 64k bulbs t5s is that ok to mix and match... and would this be good enough to bud with???
