First Impressions of LED COB Redwood-VS

I recently made the jump to LED after 20 years of growing and with the recommendation of one the members here decided to buy a Timber Redwood-VS. At $800 they are not the cheapest light but just on the reduced cost of electricity and bulb changes alone they should pay for themselves within 2 years. The reason I made the switch was because I don't cool my basement in the summer and my 1000HPS lights are always way too hot and I was hoping to reduce the heat and get better quality bud during the summer months.

The shopping experience was straight forward. They answered my questions quickly and the purchase went very smoothly. Their home page did mention that there was a month lead time on orders because of covid. After about a month, and right before I thought I might drop them a line to get an update, they reached out to me to tell me my lights were almost done and would be shipping soon. I thought it was very considerate of them to reach out to their customers like that, of course I was buying three lights and it is a small chunk of money so I would say the service matches the price.

They came very well packed. My son now has enough bubble wrap to last a few years. I was actually very surprised by the weight and quality of the lights. I just wasn't expecting them to be that heavy. A standard grow tent can certainly support the weight but I would make sure whatever you hang them on is well anchored.

I have now completed 1 grow with 2 more about 2 weeks off and I can say that they blow my 1000 HPS lights away. This has been a very hot, humid summer where I am and I made plenty of mistake my first time with these lights but I still managed to get 800 grams from my first round, or a simplified 1.3 gpw and it was easy. Just Lucas formula and minimal training. knowing what I know now about the lights I expect to increase that pretty easily. One of the biggest problems was the buds were getting so heavy the stalks all fell over and I am very allergic to "wet" weed and breakout in hives and blisters I pretty much have to let things be half way through flower. I am going to add another level to my scrog next round.

Things that I learned about the lights

1) They produced a lot of heat. They are not the magic solution to heat problems. They easily raised the temps in the tent by 10 degrees. The big difference is that although the temps were high, the useable space in the tent was more because there wasn't a death zone right under the lights like with a HPS. But you still have to have a basic control of your air-flow to deal with the heat.

2) Plants stretch like crazy. For some reason I had this idea that plants wouldn't stretch under LED as much. Whoops, they stretched more than I was used to. Next round I will top twice to deal with this issue. I did end up with a lot of smaller buds because of the stretch but they were all nice hard buds, just small.

3) Plants drink a lot more under these lights compared to HPS. I am used to having to feed every 3 days DTW in pro-mix but I found I had to do it every 2 days now. Of course a lot of this has to do with the amazing growth they showed.

4) Basic feeding works fine. I read a lot about the need for extra mg but I found that Lucas worked just fine. In fact other than the stretch I feel like there was no real big surprise.

Conclusion: I would recommend these lights to anybody. If you are using a normal HPS at the moment I dare say it would be stupid not to make the change now. I am sure that one can have the same results by DIY or any of the other quality lights out there, but if you want to spend your money in America for people who treat their customers with thought and don't put up BS photoshopped pictures I would suggest Timberland is a good place to spend it.

Are you going to show your bud pics and plant pics? Or do you have a journal for all that?

I don’t do journals anymore but here is one of cookies n cream. These plants are untrainable, will snap right off, can’t bend so these are 4 untrained plants under 600 watts. This strain will be topped twice next round. Also had lights too close and light bleached tops a bit. These are week 6

how much u feeding ppm wise and how much is your starting water your using? would like to know been thinking about switching to the lucas formula

Starting ppm is very low, like 50 ppm. I am blessed with good tap water. I think Lucas is like 1100ppm? pH is 6.3. Straight feeds all the way through, no skipping.

Yeah, I downgraded to 4 inch from 6 inch because I thought I wouldn't need it. But again, I am growing in very poor conditions. The ambient temp of my basement was around 79 for most of July and first half of August and inside tent temps got as high as 90 and probably averaged 86. Thinking of using the watts I saved from these and installing a mini-split for next summer and recirculating the air in the basement instead of exhausting out of the home. I am excited to see what these are going to do under good conditions now.

Actually I bought one of those new? temp controlled fans that you see in the banners here. I'll be honest, I have no idea what's the point of those things. I want a controller that has a minimum fan speed for air-exchange and ramps up for humidity and temp. I got dozens of settings on this thing but can't do what I want it to.

The lack of IR really helped you with the temps. Running in the mid 80's is actually where you wanna be with this light. I imagine things wouldn't have turned out as well if you had a HPS in there with the hot summer temps.

No, summer has always been my bad season, but not bad enough to not grow. This grow I vented from 3 tents into the room which was then scrubbed and exhausted outside with a 6 inch. Next summer I will either have to exhaust directly outside from each tent or add the mini-split which also makes me wonder about adding co2.

I hear ya. My electricity bills go up and my AC struggles causing the high temp cut off to kill the side lighting occasionally, I have to run my CO2 levels a little lower. Yields tend to drop from the 50's into the 40's. But it's still worth it. lol

Thanks for sharing your experience.
Do you happen to know if your cobs are 80 or 90 cri? That may explain the unexpected stretch.

It looks like they are Vero29 Generation 7 COB LED 80 chi. But to be honest I think it was just my mistake. I did not train them as I normally would and let them go 5 days earlier than normal. I had it in my head that LED grew short plants and the full spectrum would keep them short much as added MH would. They just grew very well and extremely healthy is all.

Normally I lollitop once they reach my scrog net, flip and train till I see bud formation and don't touch again. Next round I am going to top below net and flip 4 or 5 days before they reach the net and then train till I see buds. I think this should do it.

I'm wondering, what kind of problems did you experience due to the summer high temps?

Nice to see what a grower with so much experience has to say about current LED tech!

Well having temps in the 90s and humidity in the 80s just sucks all around. Plants turned out fine but I have to assume they didn’t yield as well as they could have. My dehumidifier could not keep up this year.

Just a follow up. I will soon be receiving another one of their lights. I got the smaller one (4 cobs) to do veg with and try to keep those other tents for just flowering. On my second rounds with 3 tents now and 2 tents are new strains and we'll see. The MOB I ran the first run I decided to top and some light scrogging and I don't have anything close to an even canopy. First 8 days are vital with the training, can't miss a day.

You found that no matter led or HP's that light is hot not cold and that led causes more stretch due to there being less usable light overall and in many wavelengths they miss from HP's and CMH. More efficient by a small amount but you dialled back on light there whereas HP's might have been overkill and that all effects yields.

Nobody was claiming that LEDs were not hot, although they are much cooler than HPS. LED does not cause more stretch and they have more usable light. Guy you got everything wrong.
