Just to update and conclude (my part of) this review of the Timber Vero29 4000K fixture:
I was quite pleased with the performance of the light. Again, it's built extremely well -'tank-like' I'd say.
All the components are top-of-the-line names -Vero (duh!), Meanwell, Ledil, Cooliance. The fixture ran very quietly and at a very low temperature. The emitters are driven very hard which makes them not the most efficient at full-power. I could have dimmed them via the dimmer switch to increase the efficiency, but I didn't opt for that. The plants seemed to love the intensity -even when they were placed directly under the Stella lenses. None of the plants burned or bleached at all.
I don't think the 4000K temperature is ideal for flowering. I think the flowers would have bulked up more with a 3500K temp. I got
close to 200 grams of trimmed flower (and an undetermined amount of trim-weight) under 240 watts of 4000K -Not great yield, but not bad, either. I grew in soil, tree-style with no physical manipulation done to any of the plants. I probably could have gotten more yield by using various other growing techniques.
But, on the other hand,
resin production was incredible on all plants under the 4000K. Overall, plant-health was great, too.
The 2-emitter Timber Vero240 is a fixture best-suited for a tight, rectangular space. It did fine in my square tent, but I had to rotate the plants regularly -not really a problem for me as I love to spend hands-on time with my plants!
The Stellas focus the light into a narrow, intense beams that suit tree-style growing very well because the hard-driven/focused beams can really penetrate deep into the canopy....But the Stellas might not suit a scrog style of growing as well as some lenses or reflectors.
I would like to see Timber offer some lens/reflector options that could spread the light more. The Stellas are great in some applications, though...and their 'cool-factor' is off the charts!! -just sayin' ...
Overall, the Timber Vero 240 4000K is a very powerful, hard-driven fixture that shoots for intensity over efficiency. I don't pay a lot for electricity in my small grow -(even when I was using HID, in the past), so electrical savings from a more efficient fixture is a non-issue for me. In a commercial application, it might be a different story. The advantage, for me, comes by way of similar intensity with less heat produced compared to HID.
Thanks for letting me share this thread with you, Jimmy (wherever you are!)! It was a fun grow and I think I'll break out some of that Mother Tongue right about now!!
Great light!
peace!
