yes i flower after clones are rooted and also the roots have a net pot to cling onto so they stay in place. ive talked to other people that did this and they didnt have a problem. worse case scenario il use hydroton even though i cant stand it!. i could be wrong but i really dont think its gonna be a problem and hopefully the filter is easy to clean cause then il clean it once a week. in my ez cloner i just had sensi 2 part, b-52, voodoo juice, and power clone. i had 120 plants in there for over 3 weeks without changing the res and roots were hanging into the puddle like nft and i still didnt have a problem. the other way im looking at it is theres multiple sprayers in each chamber and even if one gets clogged then theres the nft to back it up until i replace it and then if that fails then only a few plants would die. doesnt seems like a big deal when you have 36 plants unless im wrong about the amount of misters it has
