Cob tech is ok but you still get some normal issues unless your going top end. The heat is always an issue, then you have the lack of penetration. This is normally due to the angle of spread etc.
I think dependant on your grow style etc Cob Iis ok you jyst have to remember its limitations.
Budmaster are soon bringing out a Cob and it has some really nice upgrades that ill be able disclose soon! :) again BM will be hitting, or indeed possibly leading In new levels within the market.
Anyway lol. If your getting a good deal for a tent etc I'd consider it :)
