Is there anything extra special with the proof lights compared to the T 8 daylite bulbs Boboro is using ?
Seem to be pretty costful equipment or have I got the wrong picture ?

Flourescent bulbs are rated by diameter. T8 is 3/8's (of an inch), T5 would be 5/8's and so on. For growing there are typically 2 different types of lights. For flowering you want a 2700K frequency and for growing you want a 6500K. So, to answer your question there really is no difference. A T12 will use more energy than a T8 because it is much bigger.
Next year's experiment for me will be to grow a few plants under a 2700K a 6500K and a run of the mill shop light and then see if any of them prematurely flower once in the field.

As I understand it I'm looking at 6500 kelvin and a ''good'' an different thing is that electricity is included in my rent.
Thank you Randy.
Thats why I treat the snus for a week instead of 36 h............

I think I need to re-take the math quiz.
In "T8" the denominator is 8, as in 3/8.
In "T5" the numerator is 5, as in 5/8.
But...I don't see a formula for computing the "so on."

The lamp codes are say, FxxTy. First is the lamp type F= flourescent. xx= power in watts or length depending on the maker. T= the diameter in eighths". A T-8 shop lamp is a great lamp for a grow. The T-5 are a watt stopper type of lamp. (and size) No math, Like sizeing a tire for a car.
Well I don't live in Colorado so I don't know what I was smoking but.. yes T8=8/8 inch, T5= 5/8 inch and "so on"= so on/8 inch..

So, PO- How are the ones out in the patch look lately? I knew You would pull a rabbit out of the hat (with all four feet) Nice new starters!

Sorry MO , nothing as of yet , just a cloudy sky in the 50ities + alot of rain.
Warm weather is coming in this weekend with sun as its accomplice........Starting to look like a heatwave's on its way.................

No, that´s just what I had at hand, and since it was perfectly fitting the size of the grow box... To the eye it is like midday daylight, and the 4 weeks old plants did not show any sign of confusion when I moved them outdoors. But, just for sheer growth normal 6500K lights may even do better. (The levels of flicker-freeness etc. the proof lights provide are surely not needed.)
I had two seedling boxes going, btw., one under the proof lights (3x13W) and one under a skylight (with additional 25W/6400K light in the morning and evening). The plants from under the proof lights are slightly bigger. I attribute that to a somewhat higher temperature since the lightbox gets mildly warm.

Things are lookin' up for us over here on the other side , started early this mornin with a nice sun shining on the city of Halmstad where I live.
Took my little puppies outside my window and let'em bask in it all day long , no real heat in any way but a pretty clear sky and some nice 60 degs in the afternoon.
It's about time now for somethin' else to kick in and make a change to the better I'd say.
Despite the fact that I expect that nothin really is goin to come out of my first attempt to transplant this year , I hope that I still have time to have another go at it and therefore make a second attempt.
Snails have really got to the plants this year , just small one's , making such devastating damage.
I will conclude my endeavours out at the allotment in the end of this season , regardless of all the work I've put into thoose 2 patches.
I've had enough.

Go with the buckets. Plant one in the middle and put a clear cup on it .No transplant that way and no snails or slugs. When they touch the top of the cup take it off. I did that for My wife on the second run. They look good.

Yeah , its a great idea MO. I saw one guy out there doin like that and it got me thinkin mmmmmmmmmm look good.
Its a 3 mile run on the bike out there everytime I go and they will always be there , especially when it rains.

If You look on My post add on for pics. My grow blog. You will see 9 buckets that I have out front with the cup micro green houses. No hardening off needed. I like the buckets due to (I CAN MOVE THEM) They have gravel with burlap wick, dirt, Then garden soil, Potting soil w/sand then a little more dirt on top to slow evap. I don't fill with potting soil, just where they start. They do fine when they hit the dirt. The drain hole is a couple of inches above the bottom at gravel level for the wick well.

Just wanted to thank all you guys answering my question on what sort of lightbulbs to use when cultivating under artificial light.
