Please Help!!! Newbie Rapid Rooter/Hydroton Question

Hey Family i got a quick question i have some nice healthy clones Placed in rapid rooter plugs and wanted to know if i could just simply place some hydroton inside some solo cups with some drain holes in the bottom (like i did with the soil) until they get a lil bit taller then place them in their buckets because i have to get them outta the cloner they are getting too big thanks in advance guys

I don't see why that wouldn't work... in theory

you could do it but your better of going to a store or having discounthydro.com overnight the right grow cups

thanks guys my grow room won't be ready until the weekend but my babies gotta come outta the cloner but one more question, how often should
I water them one or twice a day?? (and by water I mean, place inside another cup of water for about 20 mins and let the roots soak up what they need; for the other newbies reading this kiss-ass
LOL, THANKS GUYS
