It costs under $40.

All you do is take a cutting, stick it in the neoprene sleeve and your good to go. Run straight water and you will have a 100% success rate.

Yep, I've done aerocloners before. They worked generally well for me, though I found dosing the water with 50% grade H2O2 @ 1ml/L improved the consistency across each batch. An aquarium heater in the rez, set for about 25C helps, too.

I went back to RW as I found I could get 100%, every time, with cubes on a heat mat as opposed to about 80-90% in aero. Glad you can get 100% every time out of aero- I never could.

Does your $40 account for lighting, enclosure and fans?

I'm guessing thats a no. lol VV

ive had zero success in rockwool, it stays to wet. Are you getting 100% in rockwool on a heat mat? also if you put em strait on a heat mat it gets way to hot, you need the prop trey in between which will put your cubes in the mid 70's. still i had no success. good luck

Al is on holiday so I will take the liberty of answering while I am babysitting his grow (but not the thread!). We both grow the same way (well mostly). Both Al & I get 100% nearly every time in 40mm rw cubes. We both use heat mats, Al has his clones in a thin plastic tray on the mat, I don't bother with the tray. What temp is your mat set to? Should be 30C. Is it a horticultural heat mat or are you using something else like a heating pad for people? Heating pads get too hot even on low. I tried to use one and it always got too hot.

You're watering your cubes too much. See the 1st page of this thread for info on how to water rw cubes. Dip only a corner of a rw cube in watering solution for a second or so.

Overwatering will cause slow rooting, yellow leaves, floppy leaves etc.

is this why i also get yellow burnt tips?

mine go straight on a horticultural heat mat and im doin good for succes rate they are just kind of droopy and yellow burnt tips. my watering skills could need honing as im still pretty new...

yes sounds like overwatering as well. Yellow tips and margins (edges) on lower leaves as well as that sickly undercurl are indicative of starvation of water.

'Overwatering causing STARVATION of water,' you say? Yep. Overwet conditions favour pythium and fusarium which will rot the stem tip and block the capillaries, causing wilt. Very often people conclude the wilt is because the clones are too dry, so they set about giving even more water and perhaps misting too, which of course makes things worse.

You can rescue them. Recut the affected stems and plug into new cubes that have been soaked in pH5.0 water for 24 hours. Drain as much of the water as possible by shaking the water out of the cubes. Never squeeze. Dip the stems in rooting powder & plug into new cubes. Water clones immediately with a mix of water, 50% grade H2O2 @ 1ml/L, pH to 5.8, use about 15-20ml per cube. A 60ml syringe is pretty good for accurate watering.

great thread al.b, and even better tutorial. Its key that you stress not to overwater the cubes, glad to see you did that
I hate rockwool but its made me consider making an attempt with cloning with it again. I almost kind of miss it

Yep, the trick with RW cubes is simply to not allow them to suck up all the water that they are capable of sucking up. A dry 40mm cube weighs 5g. When properly just 'damp' they weigh 20-25g. Heavier than that is too wet- water will have displaced too much air from the cube, causing slow rooting and stem rot.
