In your opinion can you use 5 gal bucket for a res? And what you you estimate it would cost to build from scratch a 4 site rdwc reason I ask is I'm looking online and found a 4 site rdwc system with a 5gal bucket for a res for $200 I haven't found many rdwc for sale most have alot of sites (6,12,24) and cost big$$$ I only can fit 4 buckets in my tent. I don't really wanna buy whole new setup since I have buckets and some of the stuff already. but just thinking about converting my current system and buying all the right parts doesn't sound fun to me. the more I think about rdwc the more I wish I had done that from the beginning seems like a better way to go. I don't have very much money invested in my current setup. So wouldn't be that big of a loss. I'm just not very handy and have a feeling id fuck up somewhere trying to switch this system to the rdwc.
