I don't think it really matters which way you choose to fill your system as neither will damage anything or cause root rot. I choose to pour water through the hydroton as it helps breakdown/reduce the salt build up. I have found this helpful especially during the final few weeks of flowering when you are flushing the system.
Would you please guide me to a link that says it doesn't?, as I was under the impression this was an opinion based on experience website?
We're not here to prove each other wrong we're here to help each other and so far no one can ever be wrong because everyone will experiance different issues, I grew a large Sativa in a DWC set up and the stem had established itself in the net pot and the top end of the roots was also present in the net pot, Upon top feeding the top few balls would dry out but the balls beneath it held moisture and that constant moisture on the roots that were not in the bubbling res solution began to rot and excrete a slimy substance (most probably a Catalyst) and in eventuality rotted my roots,not even H202 would help.
Maybe a Degree in Botany and Microbiology, will stand me in on your link ref. but I have no time to squabble with pride issues, I will unsubscribe and offer no more opinion here as I've had this issue before and feel its not worth my CAP.
