Hello and welcome to a very special episode of The D I Y Greenhouse Podcast. Today, we’re doing something a little different. We’ve received a greenhouse-full of questions from you, our listeners, and I’m excited to answer them. From troubleshooting plant problems to advice on greenhouse setup, we’re covering it all. So, let’s dive into your questions and grow our greenhouse knowledge together!
Our first question comes from Lisa, who asks, “What’s the best way to control temperature swings in my greenhouse?” Great question! Temperature control is a key challenge in greenhouse gardening. To minimize swings, ensure your greenhouse is well-insulated. Automated vent openers and shade cloths can also help regulate temperature. Consider using thermal mass, like water barrels, which absorb heat during the day and release it at night.
Next, Andrew is curious about watering: “How often should I water my greenhouse plants?” That depends on several factors, including plant type, weather, and the medium you’re growing in. A good rule of thumb is to check the soil moisture. If the top inch feels dry, it’s time to water. Remember, it’s better to water deeply and less frequently than to give small amounts often.
Here’s an interesting one from Alex. They ask, “Can I grow tropical plants in my greenhouse in a colder climate?” Absolutely! That’s one of the joys of greenhouse gardening. You’ll need to maintain a warm and humid environment, so consider installing a heater and humidifier for the colder months. Also, ensure your greenhouse is well-insulated and consider grow lights for additional light during short winter days.
Moving on, Tim wonders, “What are some pest-resistant plants for greenhouses?” Pest resistance varies among plants, but some generally hardy options include marigolds, nasturtiums, and certain herbs like basil and lavender. These not only resist pests but can also help repel them from your other plants. Remember, a healthy plant is less likely to succumb to pests, so proper care is key.
Jim is having trouble with humidity: “My greenhouse gets too humid. What can I do?” Managing humidity is crucial. Ensure you have good ventilation. Roof vents, side vents, or exhaust fans can help. Also, spacing your plants properly allows air to circulate around them. In extreme cases, a dehumidifier might be necessary.
Here’s a tech question from Jeffery: “Are smart greenhouse systems worth the investment?” Smart systems can be a game-changer, especially for busy gardeners. They can automate tasks like watering, temperature control, and even open and close vents. If you can’t be in your greenhouse daily or love tech solutions, it’s definitely worth considering. You have to weigh the costs and longevity of what you are doing. If you are in gardening to save costs at the grocery store full automation is not the route you want to take. Your costs per production will be way to high to begin.
And our final question for today, from Ron: “I’m a beginner. What’s a good first plant for my greenhouse?” For beginners, I recommend starting with something forgiving, like lettuce, spinach, or herbs. These grow relatively quickly and don’t require too much special care. They’re a great way to get your hands dirty and learn as you grow.
That’s all for our Q&A session today. Thanks to everyone who sent in questions. Your curiosity and enthusiasm are what make this community so fantastic. Keep those questions coming, and we’ll do more of these sessions in the future. Until next time, keep growing and keep learning. Happy gardening, everyone!
