We've owned the 8x10 4mm toughened glass house for just over 3 years now. We've loved owning it and it is super versatile! We've used it as a hang out space in winter when the light is low day after day so retreating into the glass house to work is so nice to get some natural light. Then we also us it as a greenhouse for plants. We've had tomatoes since October last year growning- it's now July! My recommendation is Roma, they seem to do well here in Whangarei in the glass house. Final piece of advice, buy the biggest you can afford, and fit into the space you want to locate one in. Buy the glass version and at least 1 louvre vent kit (I reckon two for the 8x10 would be better) along with at least one auto vent opener. It's a massive investment,but one we don't regret!
