Thanks for the reply, I understand the cash issue, growing is rather expensive until you make some crop harvests, but definitely when you get the opportunity check those technologies out. May I also add that the smart pots with higromite as a medium are perfect for flood and drain since they aerate by their porous nature, as well as air prune the roots, and with higromites water retention and porosity, it seems like a winning combination I'd love to use one day. As for the never knowing if your tent was toxic, well if you don't have a vent fan pulling air through and even then if you did from the stories I read of the cheap spray on pvc from the same chinese factory that mass manufactures all these tents which are the same design basically franchasied and rebranded, then if you had it your plants would be dead, really from what I read its mainly an issue with the white pvc ones in production and was a localized issue, the Homebox people had them take it off the market however individuals were buying up the left over toxic ones, rebranding them and reselling them at full price knowing this issue existed. From what I've seen these tents look like a newer rebranded Homebox, which is great. I'm glad to hear that the build is solid, I'll definitely up date when I have mine set up and my next crop ready to show.
