Got a good deal on a grow tent

I was looking for a decent grow tent without spending a fortune and saw HydroWorlds had a sale. I ended up getting a 2x4 grow tent kit, which included some basic ventilation. It was a good price point, especially with the free shipping offer for orders over $99. The kit arrived in about a week. Setting it up was straightforward, and it seems sturdy enough for my needs. For a first-time buy, I felt like I got good value for my money.

Good quality, delivery could be faster

I ordered a Mars Hydro FC-E3000 LED grow light during their recent sale. The light itself arrived well-packaged and was easy to set up. It's been performing as expected, no issues there. My only small gripe was the shipping; it took about 8 days to reach me in California, which felt a bit slow compared to other online retailers. Customer service was responsive when I inquired about the tracking, though. Overall, a solid purchase, but they could improve on delivery times.

Reliable as always

This was my third order from HydroWorlds, and they didn't disappoint. I picked up some General Hydroponics FloraGro, Micro, and Bloom nutrient solutions, along with a new pH meter. Everything arrived correctly and on time, just like my previous purchases. Their stock levels seem consistent, which is great because I hate having to hunt around for my usual supplies. I keep coming back because I know what to expect, and they deliver.

Heard about a 4/20 sale last year for HydroWorlds. Is that a regular thing they do, or was it a one-off?

M Mike 2 months ago

Oh yeah, the 4/20 sale is a regular thing for sure. It's one of their seasonal peaks, usually good discounts on a bunch of stuff.

C Colin Kaur 2 months ago

Definitely. I'd expect one this year too. Keep an eye on their site around then, usually some decent savings on nutrients and smaller gear.

Hey guys, thinking about grabbing a grow tent kit from HydroWorlds, but I'm in NYC. Anyone know how long shipping usually takes to the East Coast?

P Priya Brooks 2 months ago

Mine got to PA in about 5 days last month, so probably similar for NYC. They're pretty quick.

N Nick S. 2 months ago

Yeah, I'm in Boston and got my lights in like 4 business days. They use standard carriers, so it's not super fast but not crazy slow either.

Has anyone had to return something to HydroWorlds? Just wondering how easy or difficult the process is if something isn't right.

A Anna 3 months ago

I returned a pH meter that was acting wonky. Process was pretty straightforward, just had to contact customer service for an RMA. Got my refund within a week or so after they received it.

N Nick Ito 2 months ago

Yeah, returns were easy, did it last month for a ventilation fan. Just make sure you follow their instructions on the website.

Just wondering if HydroWorlds ever has good sales on their LED grow lights? I'm looking at a couple of the pricier ones.

R Rachel 2 months ago

They definitely do! Keep an eye out for their Black Friday or Cyber Monday deals, those are usually the biggest. I got 15% off my last light during a holiday promo.

W Wendy 2 months ago

Also, sometimes they have specific 'grow light promos' pop up. Sign up for their email list, that's how I usually hear about them first. Might get a first order discount code too if you haven't bought from them before.

Thinking of buying a starter system from HydroWorlds, but also looking at Hydrobuilder. Any thoughts on which one is better for a beginner, quality-wise?

J June W. 2 months ago

HydroWorlds is solid, especially for beginners. Their kits are usually pretty complete and good quality for the price. I started with one of their DWC systems and it was great.

S Sarah P. 2 months ago

I've bought from both. HydroWorlds seems to have a slightly better selection of complete beginner kits, and their support was helpful when I had questions about setting things up. Hydrobuilder is good too, but sometimes their inventory can be a bit more geared towards advanced stuff.
