I have constructed compost bins in the greenhouse. The rotting compost warms up during the seasons. Pots and boxes of plantlets on top of the compost - free heat, plus potting compost at the end of winter. I'm 78, my dad taught me this when I was a kid, goodness knows how old the idea is.

Gardener Scott: This is completely off-topic, but I wanted to get this message to you. I watched a couple of your leaf mulch videos and loved them. I discovered something amazing today and wanted to share this Good News. In April this year (2023) I tried an experiment. I put a shallow square bottomless wood frame on the ground. The frame is about a foot high. I filled it with leaves and watered it in. Then I put down thick black plastic that I cut holes into for drainage. I put soil on top of the plastic, filling the square frame, and planted onions. After harvesting the onions today, I removed the soil, lifted the black plastic and discovered rich, fully broken down leaf mulch. Not a sign of any unbroken-down leaves. Just that rich black gold! I was astonished at how quickly The Lord created that mulch, and wanted to share this idea with you and others. God is good and He gives us the best ideas!

I've been building a sunken cold weather greenhouse in my zone 5B climate the past few months. I will have one wall of 16mm triple wall poly carbonate sheeting at a 38.8 degree angle facing south, with the rest being solid insulated walls. The sunken part is only dug down 24 inches, but I poured footers and laid 8inch concrete block. I plan to add the back wall lined with 55gallon barrels of water, have a compost pile for the winter months, and experiment with building a passive water heater with a solar powered pump to warm the barrels during the day. The other key will be having foam bubble insulation to roll down to cover the polycarbonate wall at night when it gets down to the single digits or negatives. I do have power and will have a heater for those double digit negatives.
@WYO_Dirtbag9 ай бұрын
The greenhouse is 10x20. I'm also wanting to make expirement with circulating the warm water heated by passive water heaters though pipes in the soil in the raised beds. Get the soil itself to also hold heat. I did put foam insulation around the block to try and also keep the frost from creeping through when we hit the severe cold. But I am hoping for year around gardening in this thing. Along with the heat, the other issue becomes the lack of daylight in the dead of winter. I think I'll have no other option but to use grow lights if I want to try growing tomatoes and cucumbers. Otherwise growing greens like kale would be a safe option for the dead of winter.

I’ve wondered about using a stock tank heater in my water barrels. I am investigating how water moves when heated. What I mean is if I use a heater in one barrel is there a way to place pipes from one barrel to the next so as water heats up in one barrel can I get it to move into the next barrel by creating a current between the two…and can I add a 3rd barrel and get it involved in the process? I don’t know the science but I wonder if it will work? Maybe the heated barrel needs to be elevated a bit higher than the other so I can get an assist from gravity? Stock tank heaters don’t get too hot but in an enclosed barrel it should heat up enough to cause currents (via the heating and cooling of water). I’m thinking that small input may be enough to keep the greenhouse above freezing during our 5 months of cold temps. Or maybe I’ll just try heating the one barrel and see if just that does the trick.

Adding chlorine bleach when filling can help. The containers are sealed and filled with clean water so there is little likelihood of rankness. Dying the water isn't necessary.

I don’t think this will work with areas that are not very sunny. I just looked up my area for avg number of sunny days for December-6 sunny and 6 partly sunny. That’s not enough especially if they are consecutive. Compost in a GH is not a good idea to me. The gasses that are given off-not so good. I choose to have a small lean to GH so it’s easy to heat. I can extend growing f I choose by using small heater. My main purpose going forward is to use it for seed starting as I’m done with the mess in the house. I will also start seedlings much later when it has warmed up. Perfect set up on wish list is solar/wind/battery. I’ve done the black jugs before and it doesn’t really help. It may work better if they were in a cold frame attached to the GH so they can get maximum heat during the day. If tall plants block sunlight there will be little gain. The idea of letting GH heat to max on sunny days to heat up water could also stress the plants.

Clear works fine. The black just increases heat absorption a bit.

Do you have to increase your watering when you have your plants in the greenhouse? Are your barrels food grade? I have a 10 x 10 greenhouse. How many barrels do you think I need?
@GardenerScott9 ай бұрын
Yes, I do water more in the greenhouse. In my dry area it doesn't retain much humidity and the higher temperature causes more evaporation. The barrels are food grade. In this video I discuss how to determine the amount of water you need: kzbin.info/www/bejne/ooaalKl8lNKrr80

I have a small greenhouse that has been up for 15 years and unusable (unless I ran an extension cord for a small heater) all that time because I didn’t understand that I needed to put some water barrels in. My question though is… even though central Texas is certainly not a frigid zone, we do have another cold here in there to kill off anything in the greenhouse in just one cold spell because we go days and weeks sometime without enough sun to heat up the water in those barrels, unless I’m wrong. Don’t we actually need sun hitting those barrels to get the water warm enough to store heat for the night time? Before seeing this video, I was about to just have somebody come terret down because we had a hail storm a couple of years ago that have just torn up the roof; I wasn’t willing to buy any more corrugated panels unless I can figure out a better way to utilize, the greenhouse to start with. Now I’m hopeful! how long about do the water barrels hold enough heat to matter after say, just one day of sunlight? Thanks so much for all your information and the inside of your greenhouse looks so neat and great with your pavers and rock around your water barrels.
@GardenerScott7 ай бұрын
The sun doesn't need to hit the barrels as long as the air inside is warm. It depends on how cold the air is when determining how long the water will hold heat. As I showed in the video it can stay warm for days until there is a sustained period of cold air.

Gardener Scott, what is the name of the plant to your immediate left in the beginning of this video? I had one come up in one of my planters this year and do not remember planting it. It grew 3 feet this season so I am ready to leave it in the planter and see what happens. Looks like a fig but unsure. Thanks . ( btw, Sacramento, zone 9b, can it be left outdoors over my winter?)

@@GardenerScott will u water soil even after plants die? I don't have anything growing all winter in the greenhouse. It can get really hot with the sun on it some days and the soil really dries out. I don't add compost to it in the fall just for this reason, I wait until spring. Should I be doing something different? I can't imagine having to go out and water it all winter. I am in NH, hose would freeze, would have to lug water.

I will water with no plants to benefit the microbes. I have added compost and want the extra months of soil building. There is nothing wrong with waiting until spring. It is extra work to carry the watering can because my hose freezes too but at least it allows me to stay active.

Hi! This is Mill Town Life or JanRonandArthur. Question for you: I am having a lack of humidity problem in my greenhouse. I have a sand based brick floor and I have 15 ea 5 gallon buckets of water in there. What level of humidity should I be looking for? I know there are a lot of variables here. I live in 6a, May 17th last frost date, NE Ohio. The greenhouse is also heated. Average temps currently inside 65°, outside temps avg at about the same. Avg relative humidity is right at 55%. Any information you can pass along is appreciated. Talk to you as well on Monday! 05/06/2024
@GardenerScott3 ай бұрын
Much depends on the plants you're growing. Generally, a humidity of 40-80% is recommended. I have low humidity in my greenhouse but it is higher than outside it. I'm growing the same plants in the greenhouse as in my garden which has much lower humidity so I don't make any efforts to raise it higher. If you're growing plants only in the greenhouse that require high humidity, then you may need more, but 55% may be enough.

Hi Scott, question for you, I live in Indiana where winters can be very cold for extended periods. I grow bonsai trees. I want my deciduous trees to experience winter temps, but not freeze solid. I built an 8x12 poly/aluminum greenhouse. It has a pea gravel and paver floor. I was planning to get 4 fifty five gallon black drums to regulate the temperature. Do think this will be sufficient? Too much? Again I want it to get cold, 30-40F, but since the trees are in containers, I don't want the roots to go below that. Any advice is much appreciated!
@klokworkllcАй бұрын
I'm also wondering about these drums of water freezing and braking the drums. Do you fill them all the way?
@GardenerScottАй бұрын
It may be. Much depends on how cold it is, how efficient the poly panels are and you may need supplemental heat. When my outside temp reached a low of -14 my greenhouse got down to 14. You are probably get below zero as well and you can expect temps in the greenhouse below freezing. I suggest monitoring the inside temp during winter before relying on the greenhouse for the trees.
