Good quality, fast shipping

I ordered a CO2 Bag last week. It arrived in three days. Product was exactly as described. Happy with my purchase.

Smooth order, good support

I purchased a Growbox Komplettset last month. The ordering process was straightforward on their website. I had a question about the LED Grow Lampe in the kit, so I used their chat support; they responded quickly and were helpful. Delivery to my address in Texas took around a week, which was reasonable. Everything was well-packed and arrived undamaged. The components all seem to be good quality, especially the exhaust system. Setting it up was pretty easy with the instructions provided. I'm happy with the whole experience and the kit is performing as expected.

Decent stuff, no fuss

Got a couple of Clip-Ventilators for my setup. They came pretty quick, took about 5 days to reach Denver. Packaging was discreet, which was nice. The fans are working fine, not too loud. Overall, a solid experience, I'd say.

Reliable as always

This was my third order from Happy Grow, and they continue to be consistent. I needed more CANNA Nährstoffe and some new Steinwollwürfel. The quality of their products is always top-notch, same as my previous orders for a Growbox and LED light. Shipping was discreet again, which I appreciate, and it got here in about a week. They haven't let me down yet, which is why I keep coming back.

Love my new Growbox!

I finally got my Growbox and it's fantastic! The setup was so easy. Everything I needed was right there. I also bought some BioBizz Dünger and the plants are loving it already. Shipping was quicker than I thought, too. Definitely coming back for more stuff soon!

Hey, thinking about ordering a grow tent. I'm in NYC, how long would shipping take usually?

T Troy Foster 2 months ago

Oh, you're in the US? Happy Grow is a German store, so shipping internationally might take a bit. I'd expect at least a couple of weeks, probably more with customs.

T Tara 2 months ago

yeah, they're in germany. you might be better off with a local supplier unless you find a really good deal there.

I'm looking at their full grow kit vs just buying individual parts from Growmart. Any opinions on Happy Grow's kits?

P Paula C. 2 months ago

Happy Grow's kits are usually a good value, especially for beginners. The discount on the kit saves you a decent chunk compared to buying everything separate.

I compared them with Bloomtech before and the Happy Grow kit was actually more complete for a similar price. Plus, the components felt more integrated.

how discreet is the packaging when they ship stuff?

B Beth Hughes 2 months ago

Very discreet. Mine came in plain brown boxes with just their shipping label, nothing that screams 'grow shop' on the outside.

S Steve H. 2 months ago

Yeah, totally plain. You wouldn't know what's inside at all. They're good about that.

Does anyone know if Happy Grow accepts PayPal? Or is it just credit cards?

Yeah, they have several options. I paid with a credit card last time but I remember seeing PayPal too. You'll see them all at checkout.

Are their LED grow lights actually good quality? I've seen some cheap ones online that barely last.

F Faith 2 months ago

The brands they carry are usually solid. I got a Mars Hydro light from them a while back and it's been rock solid.

They list brand names in their FAQ, so you can check those out specifically. I think they offer a warranty on the LEDs too, which is a good sign.
