Conclusion

Whether you decide to go really big or really small with your greenhouse is totally up to you. No matter what you choose, you’re going to end up with plants, flowers, or veggies that you may otherwise never have been able to grow – and that’s worth the time and energy of a DIY project. 

Even if you have no interest in tropical flowers or fresh veggies yearround, you can always build a greenhouse for no other reason than a little warm spot to escape to during the cold winter months. No judgement.
