Clones

Is there a certain temperature if water clones prefer to be in? I've been told they like cold water. Any truth to that?

  • I would say cool 70-75 F.  Maybe cooler IDK . Warm water can get you in all kinds of trouble.

    • 65 to 68 degrees holds the most dissolved oxygen...

      That doesn't mean yours has to be that cold but it retains the most oxygen...

      • I dont think it matters much, I just noticed roots on a cutting I had sitting in a glass of water for a couple of weeks.

        If I clone in rapid rooters or rockwool I usually put a heat mat under the  tray to create humidity. If I clone in my DIY cloner I dont know because I never checked it but the  pump runs 24/7 so I would guess its warm. I dont use a dome with cloner and my results with it are nearly 100%

        •  It may not matter much in Maine in the summer, but it does south of the Mason Dixon!!

          I had to put my aero cloner on a short cycle timer during warmer months. If I run it 24/7, it warms up the water too much.

          I run Hydroguard, and still get nervous if the cloner gets above 75.

          • My timer is a Century brand.  They run about $40 on Ebay.

            I run 1.5 mins on, and 20 off. Been using it for a couple years now, if memory serves.

             

            And YES, timing is a BIG deal, running a perpetual SOG. One bad batch of clones puts a hole in the middle of harvests.

            I usually only schedule 2 wks in the cloner, and 2 more in veg. That gives me one cycle/ harvest per month. Extra time in the cloner leaves my veg area empty, and non productive.

            • Never thought about a timer, I have an extra one that came with my lights. I use a dome on my cloner. It's just a clear tote that fits perfect over my cloning tote. I have a 20w grow light that i put on the dome and it's on 24/7 when I'm cloning. It makes the clones grow the biggest sets of roots and the vegetation gets really thick. Within 7 day's, I'm potting clones.

              • @RbtAsq, I learned about the timing the hard way this grow, I am trying to keep things in sync with the rdwc and I blew it big time, lol. Oh well, this time I will SCROG the next time I will SOG and not do any testing on cloning. My plan was also 2 weeks in the cloner and 2 weeks veg also. that give the rdwc 4 weeks for the roots to hit water and 3 weeks to veg which is plenty. 

                The century timers are great but the ones from the company that bought them out, not so great.

              • This is a good question!  CPW brings up a good point about using heat mats. You would think since warm roots leads to root rot it would be bad for seedlings and clones yet many growers use heat mats to propagate.

                You dont need a fancy cloning machine! I clone using a humidity dome; sealed. Living in Texas, I only use a heat pad if its cold. But i prefer a warm, moist environment for both clones and seedlings

                • No....YOU don't need a fancy cloner. If that's what works best for me, then, yes, I DO need a "fancy cloner".

                   And there's "warm", then there's "Root rot warm".

                  • I usually pull mine as soon as I see roots so there's nothing to rot. Hydroguard is a good idea, I had not tried that.

                  • I use a homemade cloner i made from a tote. I've had a 100% success rate on roots, I'm just trying to see if there is anything I can do to better my grows.

                    • It won't matter where you put the pump. If you run it constantly, it'll heat up. And that'll heat up any water passing through it, and/ or the res it's sitting in.

                      • dont get me wrong! aero-cloners are great especially if you are in soil or coco. not so friendly with rockwool or rooter plugs. on average i get about 10-14 days from cutting to clone in a humidity dome using aloe as a rooting agent.

                        • I recently learned you dont really need the rockwool if you use an aero cloner but if you want to use them and top feed I use the split cylinders and if I put those in cube the roots grow through in a couple of days. Rockwool has gotten expensive for some reason

                        • i agree with RbtAsq i use starter plugs and a tray/reservoir under a floating styrofoam tray, dome and heating pad under the try ... most seeds germinate under warm conditions not cool not hot but warm ....  my 2 cents

                          • Why your cloning makes a difference too, I was planning a SOG this grow but as a experiment I used the AZO's method 6 in rockwool and 6 in rapid rooters all under a dome and all 12 failed (1st time ever) so it screwed up my grow schedule for flipping the lights in the grow room. Adding a week to the RDWC veg  time can cause problems. I think that is the way RbtAsq grows also so reducing the risk is important.

                            From what I am reading here and past experience is making me wonder if the rapid rooters and rockwool keep the stems at the than a stem hanging in a mist. I dont know, great question though
