Ahh, I got it. So, in soil, since the roots will grow down, that is why you need it to be deeper rather than wider. However, in hydro, since there is no soil, the roots can grow any which way they want while suspend in the water, so as long as the competition isn't too heavy for the nutes, and there is enough oxygen for the given volume of water, it doesn't really matter. This has to be how they are putting plants in containers that are only 6" or so deep in hydro grows. Is this correct?

thanks!
MaryLane Reviewed by MaryLane on . Space usage for hydro? Quick question, does hydro generally use up less room than soil? That's how it looks in pictures, but I am not sure. What I mean, is if I'm going to use 3 gallon buckets for my plants in a soil grow, would I be able to use smaller buckets if I go with hydro? I am thinking about setting up individual buckets for each plant and running each separately in a DWC type setup. The smaller the area the better, as my space is limited, but I don't wanna give up a 400w HPS or reduce my yield. Rating: 5
