Thanks for the advice mdgcmd, really good points.
Everything I've read suggests that Hydroton is pH neutral, so it's good to hear that you've had the same experience. All things considered it just seems like a hard-to-beat hydroponic medium. Much easier to keep in place (since you don't have to have small holes to keep it from falling out), re-usable if you clean it properly, and so on.
I'd thought about the CFL's, but it just seemed to me that if I went that route I'd end up using a ton of them. How does 2-3 100w CFLs compare output-wise to, say, a 2 or 4 foot double bulb fluorescent fixture (like a shop light)?
Also, I hadn't thought of the issues with root entanglement with a DWC set-up. Honestly I think on this grow I'm still going to go that way simply because I'm just going to have a couple kinds of lettuce, some collard greens, spinach, and maybe basil. (I'm leaving the training wheels on the bike, in a manner of speaking.)
Though I do have an idea for solving that particular problem... I'll have to see if I can make it work. Maybe I can come up with a new design. |
