Got a new fan, works well

Needed a new Inline Duct Fan and just grabbed one from here. It got here pretty quick, like four days, no fuss. Hooked it up, and it's doing its job, pretty quiet too. The price felt fair for what it is. Overall, solid purchase, nothing to complain about.

Smooth order, good support

I ordered the TSW 2000 light and a Ventilation Kit together. The website was easy to navigate and placing the order was straightforward. Delivery took 5 business days, which was within the estimated window. I had a question about the light timer settings when I was setting it up, so I used their online chat. The support agent was helpful and resolved my query quickly. The light itself is well-built and the ventilation kit was simple to install. Packaging was discreet, which I appreciated. All in all, a good experience.

My plants are loving it!

I just received my FC-E 4800 and it's fantastic! The light coverage is superb, and my seedlings perked up almost immediately. I was really impressed with how fast it shipped too, got here in only three days! I'm already planning my next purchase; I think I need one for my other grow area. Definitely recommend this to anyone serious about their grow space!

Always reliable lights

This was my third order from them, got another FC 3000. Just like the previous ones, it came well-packed and performs exactly as expected. Good to know I can count on consistent quality every time. Took about 4 days to reach me in Manchester.

Thinking of grabbing one of those FC series lights, maybe an FC 3000. Anyone know if they ship from the UK or if it's coming from overseas? Don't want to wait ages.

J Jacob 3 weeks ago
Yeah, they ship from within the UK! I got my TS 1000 super quick last month, like 3 days.

Hey guys, trying to decide between a Mars Hydro tent or a Vivosun one. Any thoughts on quality or ease of setup? Mars Hydro has a good bundle deal right now.

I've only ever used Mars Hydro tents and they've been solid. Got the 4x4 and it's pretty sturdy, zippers are good. Set up was easy, just follow the instructions.

Vivosun is okay but I think Mars Hydro is generally better quality for the price, especially if you can snag a bundle. Their Mylar tents are super reflective too. Plus, Mars Hydro lights are legit, so keeping it all in the family might be easier for compatibility if you're getting a kit.
