Looking good!! I have been using an aero cloner for a couple years and is the best option in my opinion!! A couple things! Make sure that the grey tote is light proof, not saying it isn't, just never used a grey one like that before! No need to glue any of the PVC fittings! I will put a link at the bottom for the best totes you can find for cloners, and if you can find the ones with the grey lids, they are even better! The yellow lids are not light proof so you need to give them a coat of black or grey primer and then paint it white the next day! With aero cloners there is no need to add anything to the water or to use any rooting gels....! I do use Rootech and scrap the stems and it does seem to help but they will root without doing those things! If you have any leaks around the lids, you can add some rope caulk or half round rubber wether stripping that has sticky on the flat part! One last thing is that I keep my water temp at 78 and it seems to speed thing up a little too!
I have a buddy, superstoner1, that makes different colored collars that are great when growing different strains and are usually cheaper than what you can buy at a storeor online!! Send him a pm ifit something you are interested in!
