Good deal, but slow shipping

Got 27% off my Hydroponic Irrigation System with a code from my favorite grower's newsletter, which was awesome. The system itself is solid, but it took nearly three weeks to arrive. Makes me wonder if Cultiuana ships from China.

Got a light, it's pretty good

Needed a new light so I picked up one of their Quantum Board LED Grow Lights. It shipped from a US warehouse, got here in a few days. Setup was straightforward, just plugged it in and adjusted the hangers. My plants are looking fine under it. No complaints, it does what it's supposed to do.

CT-1000 and accessories

I ordered the CT-1000 LED Grow Light along with a Grow Tent and a PH Meter. The ordering process on their website was easy to navigate. Everything arrived in two separate boxes within four days. The grow light was well-packaged and felt very sturdy when I unboxed it. The PH meter seems accurate enough for my needs. I had a quick question about the tent's assembly, and their customer support chat was responsive and helpful, clarifying things for me right away. The tent material feels durable, and the light fits inside with plenty of room. So far, very happy with the quality across the board and the overall experience.

Repeat purchase, still reliable

This was my third order from Cultiuana. I needed another CT-480 LED Grow Light to expand my grow area. My first CT-480 from them is still going strong after a year, which is why I came back. This new one arrived in about 3 days, same quick delivery as before. The packaging was good, everything intact. No issues with the light itself, hooked it up, and it's working perfectly. Their consistency in product quality and shipping speed is why I keep choosing them over other brands I've tried like Viparspectra.

Good deal for a new setup

I was setting up my first indoor garden, so I was really looking for value. I snagged a CT-240 LED Grow Light during their Spring Planting Sale, which saved me a decent chunk. Shipping was free and it arrived pretty quick, like four days after I ordered. The light itself was super easy to hang up, and it seems bright enough for my herbs. Felt like I got a good product without spending too much, which was my main goal. Definitely worth it for a beginner like me.

Good light, minor shipping delay

I purchased the CT-640 Full Spectrum LED Grow Light for my indoor setup. The light itself is solid, well-built, and the full spectrum really seems to be doing its job for my plants. Setup was straightforward, and it runs quieter than my old unit. The only hiccup was with the delivery; it took 5 days to reach Denver, which was a day longer than the estimate. Not a huge deal, but something to keep in mind if you're on a tight schedule. Overall, I'm satisfied with the product's performance and value for the price, though improved shipping accuracy would be a plus.

Hey, I'm looking at the CT-640 light. Anyone know if these ship from a US warehouse? Don't want to wait forever.

O Omar Carter 2 months ago
Yeah, they do. Got my CT-800 last month and it shipped from California. Came pretty quick.

Can confirm, I think they have US warehouses. My stuff always arrives in like 3-5 days on the east coast.

Can you use more than one discount code on an order? I've got a first-time buyer one and saw another for free shipping.

E Elena E. 2 months ago
Nah, pretty sure it's just one code per order. Tried to stack before, didn't work for me.

Yeah, pretty much every online store only lets you use one. Pick the best one!

Does the free shipping apply to all orders in the US, or only certain ones? Looking at a tent and a light combo.

M Mia 1 month ago
Pretty sure it's all orders within the US. I got a small accessory kit and it shipped free.

Yep, my light was a pretty big box and it was still free shipping to Texas. So you should be good.

Is Cultiuana a real company? I've seen some ads but haven't heard much about them in other forums.

A Alex Q. 1 month ago
Yeah they're real. Been around for a bit, just maybe not as huge as some of the mega brands. Their stuff is solid though.

Totally legit. I've ordered from them a few times. Good lights and they have actual US support, which is nice.

Thinking of picking up one of their grow lights, but not sure about returns if it doesn't work out. Has anyone returned a light to Cultiuana before?

E Emma Beaumont 2 months ago
I returned a smaller light once. Process was pretty straightforward, just had to get an RMA and ship it back. Got my refund quickly enough.

Yeah returns were easy, did it last month. Just make sure it's within the window, I think it's like 30 days or something.
