Review: Excellent alternative to glass greenhouse - Bought this for our daughters allotment way back in February and have only just had chance to put it together. What a brilliant poly tunnel, so large and well made, it took two of us less than 2 hours to erect but you do need at least two people to hold bits and pieces whilst the other secures the screws etc. The instructions are ok but could do with numbering the sequence of each stage as we did not realise the curved roof structures needed to be fixed to the side poles really at the same time. Don't be tempted to keep screwing and un screwing the bolds as the heads do start to wear so the alan key then slips but if you don't overtighten as it says then its fine. The reinfororced plastic cover seems really strong and fitted the metal cage really well. The heat inside once erected was amazing so the vents are really useful to have. The zips at both ends are strong and go the full length on the door ends. Delivery was really quick and the product was packaged well with no damage. I know we haven't had any high winds yet but we have sunk the bottom part of the tunnel into the ground and weighted it down just in case. It does warn you to take obvious precautions when windy but again the structure seems strong and the cover very resilient so would on that basis recommend this as its a much cheaper option and easier to erect than a glass greenhouse.
Review: Fragile and porous - UPDATE: It lasted one season. As I expected, the frame broke in two places during strong wind. My added braces and ground moorings were not enough to protect the frame which snapped in two places before the whole thing collapsed. This in a small, fully enclosed garden which is protected by 8 foot walls and dense 9 foot hedging. Don't waste your money. ORIGINAL REVIEW: This really is useless. Without the added bracing I added on install it would have collapsed in the first gale. Suggested moorings which rely upon securing the cover to hold it down are completely inadequate. I used several deep pegs for the frame in addition to soil and bricks around the apron: even then the whole thing became loose in a strong wind. The seams are completely porous and rain pours in along their entire length. The webbing straps provided to secure the rolled up doors, whilst apparantly strong, have all broken after 12 weeks of use. The light reduction is far more significant than I had expected - my meter indicates a reduction greater than 20%! This will not last a second season. All in all a waste of money.

### ⭐⭐⭐⭐ Greenhouse
*by L***N on 8 February 2019*

Let's face it- it's a cheap piece of kit. However, price isn't always a good guide. I bought this as a sort of 'shed' to allow me to store stuff ourdoors in the dry. It's not anywhere close to a proper polytunnel (I'm a smallholder an have a few) so don't expect miracles. Some reviewers had a issue with the instructions- if you've done a lot of flat-pack furniture the instructions were fine. they suggest two people to put the frame together- well, I managed pretty well on my own so two isn't essential. The poles are galvansedand of better quality than some other similar greenhouses within the price bracket. As you might expect, the bolts supplied are made of pretty soft metal so care is needed if you're using an electric screwdriver- keep the torque really low. However, it comes with locking nuts- a plus. It does need holding down as there are no ground fixings supplied. I've used some sandbags and these work fine (sandbags are easily obtained from most builders merchants and sand from the same places). I guress you'd need to be careful about where you site this- I would suspect that an exposed position in a storm would leave you chasing it across a field!
