Misting vs Humidity Chamber
Comments (5)Mist systems don't have to be expensive: $300 bucks makes a 450 square foot mist yard. 1. DIG interval timer & valve. About $100. 2. 6 fence posts. About 20 bucks. 3. 10 stud length 2x4's. About 20 bucks 4. 7 16 foot 2x4's. About 30 bucks. 5. 200 feet of 75 psi rated 1/2" water line. About $40. 6. 240 low pressure misting jets (About $100 -- leevalley.com. I'm sure there is a cheaper source. They are antelco jets, rebagged.) The posts and 2x4's are used to make a simple 16' x 16 foot to 16 x 30 foot trellis. Plant the posts. Screw a 2x4 to the side of the post with a 2' overlap. Screw a second one to the side opposite. Screw the top end to a 16' 2x4. The long 2x4 should be between. Use a single screw until you get the other end up too. At this point you have 3 pi shaped supports in a row, about 15 feet apart. 4 16' 2x4s cross these. These brace the pi trellises from bowing toward each otehr form the tension in the pipe later. Snake the tubing back and forth on the trellis. Cut scrap wood with a notch that the pipe fits tightly in, and screw these to the trellis over the pipe to keep it still. Or pipe hanging tape. Or those copper saddles uses to secure copper water pipe. The pipes should be about 3 feet apart. So if you make a 16 x 30, you will need 6 x 30 feet of pipe, plus manifold pipe and connection to timer. Experiment with a jet to get a handle on the spread, but I think you want them about 18" apart. (Depends on water pressure, and brand of jet.) You want them on both sides of the pipe, so each pipe will have 40 jets -- adjust according to spray pattern. Antelco claims a 0.8 meter diameter, but normally you put sprinklers at a radius apart to compensate for irregular patterns. Punch and screw in the misting jets. Do a single row on two pipes, facing each other. Lay down some newspapers. Turn the system on. Watch the papers and see if they get wet uniformly. You may have to adjust the spacing which means either 60 more feet of pipe or a hatfull of goof plugs. The rationale behind 3 foot spacing: If you use standard 21x10 plant trays, you have a 15" aisle between rows of trays. This leaves no tray right under the pipes, which drip in use, and drain when the system turns off. You might be able to stretch this to 3 trays side by side the long way. Experiment. . Issues: You may need to make a manifold for the pipes so that it starts and stops reasonably fast. Every nozzle will drip. This concentrates too much water on whatever is directly underneath. Easiest way is to run your aisles under the pipe. The ground gets wet. (Surprise!) This can be messy. Cover the ground with old carpet, fuzz side down. Or do the gravel thing. Misting at the edges is erratic, becuase of breezes. This can be used to harden off cuttings that have gotten a start. You can compensate somewhat by scrounging sheer curtains, and hanging them around the mist yard. locate them so they are wetted by the mist. Breezes passing through them will be humidified. Run fence wire curtain height from the ground to hang the curtains. Staple the bottom edge to scrap lumber to keep it from blowing. Note: This will NOT be successful in strong winds. You are building this in a sheltered location, right? You may want to put sunscreen cloth or lath over the top....See MoreColeus propagation under lights
Comments (5)the 8 hours is probably a bit light.. i would go upwards of 16 hours .. the 2 inches is great ... even with such.. they will bolt ... getting tall and scraggly ... what i ended up doing.. was about every 30 or 45 days.. i started a new batch.. and once they rooted ... i threw out the older ones ... sterilize your media ... see link .. as well as all tools and trays.. etc.. 10% bleach ... there is nothing worse than a gnat infestation in jan/feb when i did coleus.. i also started some impatiens seed ... about 4 months too early.. lol .. you can also start some annual seed come april or so.. i used dollar store alum. 8 inch cake pans for the rooting ... and poked drain holes in the bottom ... and the real key there.. is to take the last rooting about 30 days prior to last frost .. which for me in adrian MI is 6/1 ... so that you have fresh young plants ready to put outdoors ... not a tray of tangled roots wherein you nearly kill the things.. trying to untangle the mess at planting ... just get it in your head.. clearly.. that your goal.. is something like 6 plant-able plants at planting time [of each variety???] ... IT IS NOT TO HAVE 40 MILLION CUTTING IN JUNE.. lol ...[that was my biggest mistake.. the first year.. lol] .. OMG.. they were all my babes.. and God forbid i kill one ... lol ... ken Here is a link that might be useful: link...See MorePropagation using a mist system with poor humidity control.......
Comments (4)Summer time high heat causes plants to stress out in the GH resulting in insect invasions; one must be on constant guard. Heat and lack of air circulation is also the cause of propagation failure. Do you use at least a 50% shade cloth in the summer; have circulating fans/exhaust system? One inexpensive system I've seen for containing mist is to place clear plastic shower curtains, just as one might see in the bathroom, around the mist bench to contain moisture, yet allow some air circulation without blowing the cuttings away. Unless you have a water wall in your GH and shade cloth you may have to abandon propagation there during the brutal summer months especially if your GH has western exposure. Another system may be an inexpensive propagation set up under shade trees outside where temperatures are more moderate, just as the person above suggested. Do you keep a notebook recording details, successes and failures? Do you have a set up for min/max temperatures in your GH?...See MoreMisting Propagation - How to...? Where can I find...? How much...?
Comments (1)there is a plant propogation book i have wherein the author describes his own mist system. that author has a large black coil of hose in the roof of his greenhouse so that water can be heated before reaching the mist nozzles. that's at least one vote for using warm water and keeping the cuttings reasonably warm as they root. just thought i would toss that in! lol. -------------------------------------------------------------------------------- Posted by: mosaic z8 LA (My Page) on Sun, May 11, 03 at 11:59 With such a setup you could probably root roses under mist all winter here in Louisiana. And then as an added bonus, you could save on your power bills all summer by using it to steam your veggies :) -------------------------------------------------------------------------------- Posted by: tammyinwv z6/WV (My Page) on Sun, May 11, 03 at 16:05 i have been unable to find the mist heads even within an hr from my home.Someone mentioned here they found them for .50 each.would anyone be willing to get me a couple and mail them? -------------------------------------------------------------------------------- Posted by: wild_garden virginia z6b (My Page) on Sun, May 11, 03 at 16:32 at my lowes store the mist heads where in the indoor gardening area next to the register, i doubt the people at lowes would have even know what to look for. it was with the drip irrigation supplies, as i said in the indoor gardening area next to the big outdoor area where they sell trees and things. -------------------------------------------------------------------------------- Mist heads supply source Posted by: RoseHawke 7b AL (My Page) on Mon, May 12, 03 at 10:37 For you folks that haven't been able to find the heads locally, try going to this site: Dripworks or here's a direct link to one of the pages with some heads:Misters . I just a couple of weeks ago ordered some irrigation supplies from them and received them quite quickly. About 4 days if I remember correctly. Haven't had a chance to put it together yet, which is probably just as well as the flood we had last week would've probably washed everything down the creek ;-). I also have the Melnor timer, and it does seem a bit confusing about its ability to do a mist cycle, but what you're doing is programing it to do one cycle (on in the am; off in the pm) and punching in a choice of watering pattern, in this case the off for 10" on for 2" pattern. I believe the idea behind the pattern was/is actually to help prevent water run-off when doing overhead watering by allowing the water to soak in between the on phases. I bought this particular timer though because when I looked at it my mind said "Ah! Mist!" (heh), even though the reason I bought it at the time was to keep a new patch of zoysia sod watered until it rooted in. My batteries did last all season last year, but it was only opening that valve 4x a day for 3 weeks, and then 1x every 4 days for a couple of months. I can see where a misting pattern of opening and closing that valve many times during the day may eat batteries, but as ShamanSherpa pointed out, it's still cheaper than a $100+ misting timer! -------------------------------------------------------------------------------- Posted by: patclem z7 (or 6) TN (My Page) on Fri, May 23, 03 at 8:32 Regardless of how much water it wastes, etc, I decided to experiment with misting. I am TERRIBLE at rooting cuttings. I've tried baggies. I've tried jars. I've tried special cutting trays with plastic domes. I've had one rooted cutting out of probably 50. I had the same problem finding true super-fine mist systems in the south. None at Lowe's, none at HD. They're not popular here because they don't have the same evaporating effect they have in less humid areas of the country - they make you wet here. Here's where I found mist heads. They didn't charge me anything for shipping. They were super-good to deal with online. Web Page - Phone/Fax 888-693-0578 Local/Fax (719) 495-2266 Qty: 4; Sku: 6W401; Product: Monarch Misting Nozzles M-1; Amount: $7.40 Qty: 4; Sku: 6W519; Product: Reducing Tee for Monarch Misting Nozzles; Amount: $4.40 You have to go to Lowe's or local hardware store and get a hose adapter, timers, 1/2" PVC, PVC caps, etc. I have mine set up with 2 mist heads, and about a 6' diameter section of my grass is soaked! I don't have mine on a timer yet. Results? I don't have any yet, except none of my cuttings have turned black yet. PS - I AM NOT AFFILIATED WITH THIS BUSINESS IN ANY WAY! Here is a link that might be useful: Mist Heads -------------------------------------------------------------------------------- Posted by: fuselighter 7/WA (My Page) on Thu, May 29, 03 at 21:41 I am so excited about the misting bed. I went out and bought all the supplies today. Total cost was about $15 (my husband had PVC and elbows left over from installing the sprinkler system). I would like to go to an intermittent system eventually, but for now I am going with continuous. The water bill is not an issue because we have an irrigation system (there is an annual fee but it is not based on usage). I set the whole thing up in about an hour. -------------------------------------------------------------------------------- Posted by: debbinard Z4CO (My Page) on Sun, Jun 1, 03 at 10:54 Shamansherpa -- I could not open your picture! I live in Colorado, it gets very warm middle of June (up to upper 90's) and stays low humidity. We are on outsidewater restrictions 2xweek, so I'm not sure this method would fly. Am wondering how visible this is, or if inside is an option under lights. At any rate, I would like to propigate some rose cuttings now (is this a good time?) My daughter in law is moving and would love some plants from a rose with sentimental value. Is the rooting hormone used just the usual or special for roses? Thanks Deb -------------------------------------------------------------------------------- Posted by: mytrid Zone8b Florida (My Page) on Sun, Jun 1, 03 at 13:48 Deb, Maybe you could call your water extention office and see if you can get special permission, exsplain to them how little water it uses. Yes you use rooting hormone, there are many available. Dip and grow I here is supposed to be really good. I got some of the more exspensive stuff from a friend whom bought it threw rose imporium on line. But you can always use something like dip and grow. Deanna -------------------------------------------------------------------------------- Posted by: rose_enthusiast z7 TX. (My Page) on Sun, Jun 1, 03 at 15:47 Hi there Deanna! It seems to me you've managed to help a lot of people with your invaluable info. And I would like to thank you for inspiring me to start a misting bed to root my cuttings. I have one question to add to the many others you've been getting though... What rose company is it that you get your rooting hormone from? Is it Rose Emporium or the Antique Rose Emporium? I would like to purchase this product as well, since you and this company are using this to successfully root your cuttings. Thanks Again, Carlos -------------------------------------------------------------------------------- Posted by: mytrid Zone8b Florida (My Page) on Tue, Jun 3, 03 at 1:31 Carlos, Thank you but we should all thank AngieAnders, she is the one who did all the research and work to discover this method and then post it here for us last year! She truly diserves all the credit. I just wanted to keep any new people aware that have just started rooting this year. Best of luck all and don't forget to post your sucess! Deanna -------------------------------------------------------------------------------- Posted by: epiphany z5b PA (My Page) on Tue, Jun 3, 03 at 9:28 I found the Arizona Mist system which is by Orbit as mentioned at Wal-Mart. It has 12' of tubing, end cap, six misting heads and hose adapter for $14.95. Of course, it is once again cold and wet here,......all of a balmy 56°. -------------------------------------------------------------------------------- Posted by: auntnana 6 TN (My Page) on Thu, Jun 5, 03 at 13:06 I ordered the misting heads mentioned above from Dripworks last year and they don't put out a fine mist as much as they do a fine spray/droplets. And even though I had a pressure regulator on there, I kept having a problem with the heads blowing off! (Their drippers work perfectly by the way so it's nothing against the company) I ordered foggers from Misty Mate this year and they put out a super fine fog. Perfect for propagation. They are a litte more expensive than the ones from Dripworks but worth it. And if you ask they will ship the misting heads for $1.50. I went to HD and bought a 10-24 tap and drill set (3.00) and drilled holes in my 1/2" cvpvc and the heads just screwed right in! I bought a Melnor timer at HD for $39 and it has 1 minute spray options so I've got it set for 1 minute every 10 minutes. Can't remember the model number but it's not the one on the HD website. I hope to finish my new propagation box soon. I built one on a stand this year so I can move it around easily. Wouldn't you know, HD has plastic sheeting made just for greenhouses that I used! It's not the real thick heavy stuff either. It's only 4mil and is crystal clear see-thru! Hopefully I'll be finished this week!...See More- 6 years ago
