I love my new greenhouse! Instruction were good but pay attention to the holes lol
It's was amazing that all the parts had sticker and when one was missing it was super simple to figure out which one it was. It took us 3 days to put it up but only because we are very busy and had not an entire day time to do so.
I would recommend to put a wooden frame underneath because it helps with stability and gives you an easy way of installing anchors.

My review and assembly tips of the ONLYCTR 8x16 Green house
I need to first say that the communication with company is great, They answer messages in a prompt manner and want to make sure you are happy. After receiving the unit all parts are marked very clearly
and everything their be sure to check off all the parts just in case your missing something.
The manual and assembly instruction's are very easy to understand. Ok the build I cannot stress enough
that to have a good green house you need a good foundation this will not last without it.
I compare this to a more expensive unit and yes they will not last without a good foundation.
This unit is just as good as the others on the market that are twice as much.
I live in west Texas so I needed to build this to handle wind. YOU MUST have a good foundation.
I started with tilling out the area that I new I would use inside. I placed the bottom tracks of the unit to mark were I wanted my landscape timbers. My bottom tracks will sit in the middle of the timbers.
Then I place landscape timbers around the perimeter were the green house will sit. After squaring it all up I marked and drilled 16in down for my up right post's and set in concrete. Before assembly be sure to make sure everything is square and plumb measure corner to corner. Lay out the bottom tracks and secure to your timbers/foundation make sure everything is good and square IT IS A MUST the ruler don't lie. If you measure out from each corner
72in and put a mark you should have 101 13/16 diagonal on all 4 corners and then it will be square. I ended up building the two end's and installing the panels like the manual said and then put up the rest of the frame. See picture.
Ok Tip's
#1 Buy a box of #10 flat washers or 1/4in flat washers at the hardware store to use with item #41
Do not over tighten this hardware it will spin in the track. I think they need to redo this hardware its not that great all the need to do is make it wider so it will bite better and better holding.
#2 Run a bead of silicone around 2 long sides were panels set in. The panels well flex enough buy pushing up on the center to bow the panel, I put in the panels in a manner were I did the long side and then just slide up or down about a ½ in to set in place. Do not put silicone on very bottom track moisture need's a place to get out.
#3 When installing all the Horizontal and Vertical tracks be sure all the spaces are even and square
#4 Use Loc-Tite red on all the hardware and do not over tighten as for kinda soft threads
#5 I secured my bottom tracks to the timbers but drilling thru the track on the inside
and using a 3 ½ deck screw and used a # 10 3in flat head screw on the side upright track to secure to the 2x4 horizontal's, drill right in the center and you will miss the panel
This unit has already had 30mph winds and it not going anywhere.
#6 I also added a pair of 12in fans that I got from Amazon

Screws should be bigger and does not like bad weather.
Assembly was straight forward
Kindle Customer✓ Verified Purchase•July 31, 2023
Built over existing 8x4 raised bed. Plan to put a few stand alone pots for tomatoes inside as well.
GOOD COMPANY

Good Company. A part was missing when we got it but they sent another one out immediately. I Would recommend this green house.
