Customer Reviews
Overall good experience
I ordered a Growbox Komplettset and an additional Hesi Düngerset from Happy Grow. The ordering process was straightforward on their website. It took 5 days to reach me in Denver, which was reasonable for an international shipment. Everything arrived well-packaged and in good condition. The quality of the components in the Komplettset seems solid, and the instructions were clear enough to get started. I had a quick question about the CO2 Bag, and customer support responded within a day with helpful information. I appreciated the detailed product descriptions online, it made choosing the right setup much easier.
Decent grow tent, slow shipping
I purchased a Growzelt and some BioBizz Dünger. The tent itself is quite sturdy and seems well-made for the price. I found the zippers a bit sticky initially, but they smoothed out after a few uses. Shipping, however, took closer to a week and a half, which felt a bit long, especially since I was eager to get started. The packaging was discreet, which is a plus. Customer service was polite when I inquired about the shipping delay, but didn't offer much in terms of a solution. Overall, a solid purchase, but they could improve on delivery times.
Good deal on a starter kit
I was looking for a good price on a starter setup and got a really good deal on a smaller Growbox Komplettset. I also snagged some Jiffy Torfquelltöpfe. The total cost was quite a bit less than what I saw at other places, especially with the Komplettset Rabatt. It felt like I got a lot for my money. Worth it.
Got my LED light
Just got an LED Grow Lampe from here. It came pretty fast, like four days, maybe five. It was easy to set up, just plugged it in and it worked. Looks good, seems bright enough for my plants. Happy with it.
Love my new system!
I just got a Hydroponik System from Happy Grow and it's fantastic! I was looking for one for ages. It arrived super quick and was packed so carefully. Setup was surprisingly easy, even for me. My plants are already looking so much better under it. I'm telling all my friends who are into gardening to check them out. Definitely buying from them again!

Hey guys, planning to order a full grow tent kit from Happy Grow. Anyone know how long it usually takes to ship to, say, Miami, Florida? And is the packaging discreet?
Thinking of getting one of the LED grow light bundles. Are the discount codes usually worth it, or should I just wait for a seasonal sale? Also, can you stack codes?
