5-gallon bucket with lid and 8-gallon bucket with lid, ideal for hydroponic, aeroponic, and aquaponic growing systems. The square bucket design offers a space-saving advantage over round buckets, allowing for tighter spacing and better alignment in your grow tent or greenhouse kit. The flat sides make a more leak-proof and reliable seal to bulkhead fittings and grommets in DIY hydroponic growing systems including deep water culture, DWC recirculating system, and RDWC system. Pair this square 5-gallon bucket with 4” or 6" net pots and lids to make your hydroponic grow sites.
