Hello Everybody! It's time for me to do another journal. Now that the comparative grow is completed I find I'm missing doing my regular updates. I sincerely hope everyone will follow along, ask questions, share ideas and photos of your plants and grows. Let's jump right in here and tell you what's going on.
I was contacted by Rick from @BESTVA LED and asked if I would be interested in doing a grow journal using one of their relatively new Pro4000 series lights. As I was preparing to do an auto flower run in my 3' x 3' grow tent I thought it would be a great fit and have plenty of power drawing 415 watts from the wall. Now I won't do a sponsored grow with just any light because let's face it we can only do so few grows in a year I don't want to do one under an inferior quality light. So before I said yes I did my research and was very pleased with the components used and the design and build of the light. I'll go into more detail as I go along. The whole beginning of this journal is all about the sponsored light. I want to share the results of my research. If at any time during the duration of this journal you would like to purchase one of these exact lights contact me via PM and I can share with you a code that will take 15% off the retail price.
This week UPS dropped off the Bestva Pro400 and I was pleased to see that the box was not a billboard advertising what's inside.
The light fixture itself was protected very well with foam and the corner protectors were a nice touch. I proceeded to cut open the packaging and removed the light.
Upon lifting the light out of the box I immediately noticed the weight of the light. Heavier then any other light I have used to date. Two things caught my eye right away and that was the thickness of the heat sink and that the fixture has two drivers. So my thought process is that the thick heat sink should allow the light to run cooler as it will dissipate heat better and the dual drivers should allow each to run cooler thus helping the fixture to run cooler. But I will be the first to admit I am no expert on anything electronic or electric.
One of the things that made doing this grow journal with the Bestva light a no brainer was their 420 rep Rick. He and I talked about this journal and I asked him what he wanted me to do if I saw aspects of the light that I felt could be improved upon and I was real pleased when he said to post them right here in the journal. He said he is not an expert either and if there were changes his company could make that would make the light better for growers he definitely wanted to know about it. So I am curious about the weight of the light (20 lbs +/-) and about the use of 2 drivers. Rick @BESTVA LED welcome, and what can you share with us?
Once the light was unboxed it was time to get it hung up. And here I ran into my first snag with the light. I absolutely love the way the hangers attach to the top of the light but as you can see in the photo having 4 different cables running to a single central hook from which the light is hung lost me 15" of height between the top of the light and the top of the tent. In other words with the light raised all the way up it would stop about 18" from the top of the tent. Not a problem if you have a really tall tent or really short plants. But the light also wanted to turn from that single central connection. See what I mean in this photo here.
I have already mentioned this to Rick with Bestva and they will be looking into this. This really isn't an uncommon problem just maybe a little more pronounced with this fixture out of the box. But it was an easy fix that most of us could do but it would be nice to one day open a light and the hanging system was such that it maximized the use of the tent height however tall the tent may be.
I fixed this by running a cable on both the left side and the right side from the front to the back with the cables just long enough to make it and then used an adjustable hanger on each side. Worked like a charm and I can get maximum height with the light now. After the quick fix I got the light hung in the tent, set the dimmer knob to zero and turned on the light. Slowly I increased the intensity and was extremely pleased with the dispersion of light. This light will do a fantastic job in this 3x3 tent.
Initially when I installed the light I placed three of the four plants for the grow journal in it and got out my Lux meter to take some readings and get the dimmer set where I wanted it. Take a look.
So now the light is all set up, the plants are in and the journal is live. Before I move on to the plants let me share some technical data with you about this light. I know there are guys and gals on here who have a vast knowledge of LED lights. Please share your thoughts on this light based on the information here. This info is from the Bestva web site.

SAMSUNG LED& MEAN WELL Driver
Highly efficient SAMSUNG LM301B up to 230lm/W powered by Mean Well HLG series Driver provides minimum loss of power and long-life. We use a 3mm thickness aluminum plate radiator for better heat dissipation. Holes on the aluminum plate and the glass make heat convection, run 50~60℉ lower than any other LEDsIf you are interested in learning more about this light here is a direct link to this light on the Bestva site.

I am skipping to page two to talk very briefly about the plants I am running in this journal.
I wanted to mention that the plants are being fed 3 grams per gallon of their nutrients. I don't believe I can post the name of the nutrient company here. Hopefully I am mistaken about that and someone will correct me. I use the same nutrients for my photo plants and have fed them as much as 6.5 grams per gallon so these autos are getting less then 1/2 that amount. Rick from
