Hey now couple of quick questions:
-
Why are the 4x4 tent stabilization poles always out of stock for US buyers? And why list them on your US site at all if it’s going to stay that way?

I bought an FC-6500 in 2021 that came with a Mosmo driver. That model driver came with a type-B PWM dimmer. Truth? I bought another FC-6500 in 2022 that came with a self-branded driver. It does not seem to work daisy chained to the first FC-6500. I’ve read the self branded driver comes with a type-A resistor protocol dimmer. Is this an incompatibility issue?
i assume you grow them large before going outside thats a strong light lol

Well, I was getting leggy seedling germination, so this should help. Last year, i had some plants that were 18" tall before they got homes outside, but most all of them made it. I have only been at this for 2-3 years, so lots of stuff still to learn.

Growing cannabis indoors allows for complete control over environmental variables and results in higher yields, while outdoor growing offers natural sunlight and nice yields, but also exposes plants to pests, extreme weather conditions, and limited control over the growing environment.
Do you prefer indoor or outdoor growing? Why?
Thanks for the response on the different driver modules and issues with dimmer control.
As to the out of stock issue, the 4x4 tent is in stock. But that’s not what I’m referencing.
I’m referring to SKU MH-120SupportPole
As you can see, the site says in stock until you select shipping destination as US Mainland. There it shows Out of Stock. This is very odd. Are you sure there’s not an error in how this is loaded?

Thank you for your information. I am sorry for the misunderstanding caused to you. Since we can choose the country of delivery on the website, we show that there is stock in Canada. If you choose the United States and it shows out of stock, it means that there is no stock in the United States. Really Sorry for the inconvenience caused.

I think this was already covered…
Sorry for the misunderstanding caused to you
I have 2 FCE-3000’s side by side spaced out about 12 inches … obviously the light intensity is greater in the middle …how far should I space the two lights out ? Should I stagger them ? Is it able to cover a 6x6 or a 8x8…smaller?
The core coverage area of FCE3000 is: 2.52.5, two FCE3000 may not be able to cover the area of 66 and 8*8,
For detailed information, please refer to the following link:
