Build a Clone Machine step-by-step how-to instructions. Building your own clone machine for marijuana plant clones can save you money and allows you the chance to customize your clone machine to the size and to the amount of clones it will hold. My method costs approx. $90 compared to $300 EZ Clone Machine – 30 from hydroponic grow stores.

Step-by-Step Video on How to Build a Clone Machine

This step-by-step video will show you exactly how to build a clone machine. I use the easiest and most cost effective way their is. As you can see in all of my clone pictures and videos, every clone I have is very healthy and 100% of them root within 5-6 days. I will be adding more videos in the future as I continue to find new and improved ways to build a clone machine.

  • good choice! peat stuff is junk!!

  • Joe

    I tried peat and the jiffy cubes. Don’t like them. They fall apart and the debris clogs the spray nozzles. Went to Rock wool as you described.

  • yes 24″. 2 tubes in 1 fixture and thats it. yes soak the rockwool for 15mins prior to using. tap water is fine. yes nutes in from the beginning

  • Davebob

    Thanks. Sorry I have just watched your videos. Are the lights the 24 inch tubes? If so how many do you have over the cloner?
    Do you soak the rockwool to get it to pH 6 or in pH6 water?
    My water is very hard here and I use an RO system to bring the ppm down to 275-300. Given that should I use tap water still?
    I haven’t encountered the nutes you describe, but that isn’t saying much. Do you have the nutes in from the beginning?

  • testuser

    all of these answers are on this site.
    i let the air regulate the water temp. air temp is 75*
    pump is on 30mins every 6hrs
    flourescent lights with agrosun bulbs
    always use rockwool
    do not use RO water. ph 6.0 – as u can see in my vids and my site the nutrients i use are rockwool 1 a&b

  • Davebob

    I saw your video about the clone machine and I plan to build one.
    1. What is the temp that you have the water at?
    2. Do you control that or do you just let the air temp set the water temp?
    3. What temp do you put the air at around the cloner?
    4. How often does the pump run?
    5. What lighting do you use for the cloner?
    6. Do you always use Rockwool in the baskets for the aeroponic system?
    7. Does the water have any nutrient in it or is it just RO water set at pH 6?

    Thanks for your help. Your videos are very good!

  • you do not need distilled water.. tap water, fill reservoir or containers… let sit for min of 24 hours to release any impurities. then set ph to 6. use that water for 5 days at a time. then flush, clean and refill.. yes use an airstone!
    run the water for 30mins every 6 hours.. so a total of 2 hours a day of feeding.

  • greg

    your video was on point – everything came out perfect except i had to make the pump come out of the size instead of the bottom because the pump was too big and kinking.. i have a few questions.. how long do you keep the pump on and water the clones? Also, do you need to use distilled water, if using tap water, what is a safe PH? I also saw on the site something about an airstone, do I need that as well? Or if there is anything else that I need? thanks so much for your help!

  • no i have not used peat pellets. I have seen them in grow rooms, but no personal experience with them

  • thomas

    have you ever used peat pellets instead of the blocks??

  • thomas

    ok got it..have you ever used peat pellets??

  • no lid is not needed.

  • it recycles for many days, but i always drain – wash – refill every 4-5 days. yes, u r correct about pump and spray!

  • thomas

    and what about a lid? should there be a lid to keep the humidity in there??? first time grower and have about 30 plants going and want to take clones off em..

  • thomas

    so do you just continue to fill the tub with water or does it just recycle the entire time?? i know ther is a pump in there so thats just to push the water to the nozzles then it sprays and drips back down in the tub and recylces itself???

  • all of this stuff is on this site under grow room supplies . everything u need!!!

  • i have plenty of links to them here on my site via amazon.. (cheapest $$).. go under grow rooms, grow room supplies, then you will see everything u need!

  • Linda Smith

    I forgot to ask also if anyone knows where I can go to get all the nutrients and rooting gell and netty pots this Lowes is just opening and they dont have all the stuff I need until the spring?

  • Linda Smith

    where on ebay can I find the sprinkler heads? The only sprinkler heads our Lowes has is the ones that you have to adjust.

  • 1/2″-5/8″ hose depending on what your outlet size is on your pump. most require a 5/8″ outside diameter (OD) x 1/2″ inside diameter (ID) hose. Lowes has these where u can cut how much u need,

  • jj

    Jeff I went to Lowes and there were tons of different kinds, also, anyone know what size hose to use?, i may have bought the wrong size??

  • you can use a small tupperware, keep approx. 1/2″ water in it all times. keep it aerated. ive grown 300 plants and the effect on the water bill is like having 1 more person in your house.

  • George

    If one were to grow a single clone with one rockwool cube, what would be an efficient way to water it correctly? Fantastic system, just worried about the impact that would have on my water bill…

  • ebay, amazon etc… everywhere! ;))


    all this stuff is on Ebay and it’s cheap!!!!!!!!!!!!!!!!!!!!!!!!! Excellent! You have saved me Big Time Bucks :~)


    I cant find the spray heads????? can someone tell me wher to buy them?


    I cant Thank You enough, you did a hell of a job and I most certinly am following your footsteps.
