I want to build a custom indoor greenhouse. I was thinking of using aluminium extrusion and perspex sheeting or perhaps finding old aluminium windows that fit the space. Has anybody done anything similar or have some inspiration? Or other ideas?

I have an area that is 1500mmW x 1200mmH x 400mmD, in imperial measurements that'd be roughly 5ftW x 4ftH x 1.3ftD.

I'd like to make it a closed system with temp, humidity, O² and CO² monitoring and control. I'm wondering how I might manage water pooling in the bottom. I need to design a reservoir the same size as the green house to capture the condensation and pump it back into the system. My current idea is a custom acrylic, stainless or aluminium reservoir.

Any help, inspiration, ideas or links are appreciated.

Thank you

Got these for free! Actually got everything in this picture for free!

I've recently purchased a house where there is a wooden structure against the back corner of our fence. I'd like to turn it into a greenhouse but I'm unsure how I would insulate the fence. I was thinking of foam or rubber sheeting but I'm afraid it would trap moisture between itself and the wooden planks. What would be the best way to do this? This is the best image I have so far. Thanks

Hi all, I am a student from Singapore and I am collecting data related to problems faced as a greenhouse owner. This survey about 3 mins or lesser to complete. Can be done even if you do not own a greenhouse. Thank you!

Recently had a 28-ft greenhouse delivered and I'm wanting to run guttering along both sides to route to a rainwater collection system. It seems the only decent mini gutter system I can find is only available in the UK. Does anyone have any suggestions? External mounting seems to be very limited when it comes to space, which is why I'm looking for something smaller than house guttering. Thanks in advance.

Hi all, I just looked a new house that advertised a greenhouse and pool. Sounded good so went to see it. The greenhouse was made of old, dirty fiberglass roof and walls.I couldn't see in unless I went in they the door. I'm not sure what I could do with this. I decided I didn't care for the house but that "greenhouse" left me wondering. It has fans, vents on both ends and hanging lights. It's plumbed up to the house for watering. I think it's 12 by 48 feet.

What cam I use as a frame?

I’m currently using this hoop house as a shed and it’s absolutely terrible as a shed. My wife and I are getting into gardening now that we have ample space and I thought we could reuse this as a greenhouse. Does anyone have suggestions for where to buy a new roof/cover?

Or should I try to sell this thing and look into something different?

Anyone have any recommendations around products and/or resources for setting up irrigation in a hobbyist irrigation? Was going to get creative with some outdoor irrigation supplies but thought I’d check first

What do you guys use to heat your greenhouse in the winter? Looking for a solar heater or some type of Solar energy that I can plug a heater into...

Hi Im total noob in farm and gardening.

Trying to grow beans during this winter in sydney. Currently its way below 10 C for half of the day. and up to 20C during the day.

Q: Is inside greenhouse soil should be warmer than outside temp?

Whats the easiest option warm the soil and greenhouse?

Or any suggestion please..

My wife is a candle lover 😍

Major screw up on my part. 3b🇨🇦 nights were cooler so i have been closing up the greenhouse at night. Friday am i forgot to roll up the sides. It reached 32C while i was at work and i cooked everything inside. Lost all the tomatoes, all the peppers too. There is time left for a small crop if they come back but this was going to be my best year so far! I am so disappointed in myself. Can't even go in there to sit. It looks awful. I think i may have cooked my ginko too. At least i have the raised beds to take my mind off it I'm sad

Hello!! I am a student at Muhlenberg College, doing research with fertilizer and pesticides of all kinds. I'm trying to get a better understanding of what gardeners (of all experiences) use in their garden, and their experience with gardening in general. Please fill out my quick 3-5 minute anonymous survey! The only "identifying" question is where are you residing, but you can just put the state and country. This question will help me get an idea about how different locations think about gardening products and their experiences with them. Thank you :) 🌱🪴

Let me know if you have any questions!

I'd like to mount those polycarbonate sheets to 4x4 vertical studs - so that a left and right sheet come together in the center of the 4x4. Then on the outside I'd like to put 1x4 cedar trim over it (flat end against the two adjacent sheets of polycarbonate) to hold it in place.

I've seen a few greenhouses that look like this but a lot of the details regarding weather proofing etc. are left out.

What kind of weather stripping or sealant or tape (butyl tape?) do I need between the polycarbonate and the lumber?

I imagine I need some sort of spacer between the 4x4 stud and the 1x4 trim in the center of the two adjacent sheets of polycarbonate to prevent the trim from compressing the polycarbonate. I'm picturing that the stud, some sort of center spacer, and the trim together would effectively form an H-channel. What can I use for this?

And then finally, can I screw the polycarbonate to the stud behind the trim so close to the edge of the polycarbonate, or do I need to run purlins horizontally and screw the sheets to that?

This is for 25mm polycarbonate sheets (12ft x 4ft). There are no Lexan based H-channels for 25mm, and I don't like the look of the aluminum ones.

How are your plant results?

Is it necessary to constantly aerate rainwater storage? I have 2 250000 gallon rainwater collection tanks on property that collect rainwater from the roofs of greenhouses. This is in central Florida, so water is pretty regularly added to the system. When I got here, there was a small aerator pump connected to both tanks that ran 24/7. After replacing this 3 times over the course of about 4 years, I decided to scale back how long the pump runs to about 16 hours a day. This water is only used for wetting evaporation cooling pads, so no plant or people come into contact with it. The tanks are gravity fed and the inlet is at the bottom of the tanks, so new water comes in the bottom, and old water spills out through a spillway at the top. Do I need to keep that pump running 24/7? Could I reduce the amount of time it runs even more?

I'm in search of a replacement part for my aluminum frame greenhouse. A strong wind caught the window vent, and ripped it up so hard that it bend and tore the aluminum around the plastic panel. Any ideas where I can get a replacement?

Has anybody experimented with using timing valves for both the water source and draining the hoses during winter for your irrigation system as well as a timer for turning on the pump in the use case where it is well water?
