  1. I have a cash crop 2.0 it did the job , I got an 1.5oz. I got this after harvest, got 5 oz first run, with one beefy plant. It was well worth it, I didn’t touch it except for once a week basin cleanout followed by nutrients. I’m currently running the crop 2.0 for veg and this for bloom.

  2. I already had the Ghost Mini, and it was perfect for starting plants but I needed more. This is doing the job for me very nicely as my flowering chamber, and I’m doing all my veg stage in the small box. I like it as my grow time is basically cut in half by vegging in separate box altogether.

  3. I want to start off by saying I highly recommend this unit. I’m halfway through my second grow. Some things I will say… This is definitely for 1 or 2 plants MAX if you plan to do a full grow cycle in this cabinet. That being said… It’s a very good box for the price. The light is great quality (I chose the 300w Dual Exhaust), still have plenty of Nutrients left for at least 2 more grows. You will want to make sure that you light proof the lid.
    My first grow I tried to fit 3 mature plants… IT DOES NOT WORK! 2 MAX!! I was still able to get a modest harvest, and I’ve never tried growing before. So I can say it’s VERY easy. Just make sure you set aside 15 to 30 minutes a day.
    Also, sign up for a UPS account. That’ll be the easiest way to track the light, as it ships separate.

  4. I plan on submitting a review after my first grow finishes. I’ve done dirt but this is my learning kit for hydro. First off, if you’re extremely impatient as I am, understand there’s going to be several pkgs. I have everything except the CO2 tabs, timer, and grow cubes. Decided not to wait. I got the 300W LED and glad for it. Its the MarsHydro. I Believe its real (entry or older model) as real close scrutiny doesn’t reveal any flakiness. Gonna c how the ladies like that 300. I’ve seen reviews slamming the build quality , they’re full of crap and u can tell your nosy other its an air scrubber because it kinda looks like a speaker cabinet 🙂 ! Also, I’ve seen a complaint about fan noise, also BS. Not much louder than my laptop. Build is good, better than I though it would be. I haven’t checked for light leaks cuz I’m doing autos. If I do anything else, this box will be clones or seedlings so leaks won’t matter (and from looking over the box I could fix any leaks super quick n easy). If I were going to complain, it would be about no larger boxes (I understand the owners reason and would do the same, maybe Unique could consider a DIY kit for a bit larger size?), or if the PH levelers have no strips with them, or cuz the light doesn’t have on/off switch. Not valid complaints in my book. I don’t care much since I love advanced nutes and I’m using their PH perfect products in this anyway and a timer will work for the light if I don’t go 24hr. Bottom line is if u need a personal box or a box for clones/seedlings this looks to be the best option for price and product. And if you do need to get in touch, you won’t b waiting long at all for a response. So, for what I got for the price (even considering the few things still to come), Unique Hydro has made a big fan of a critical, grumpy old person. Definitely recommended.
