James68,
I think he was stating that it was 70° in Florida? USA. .
Shoot James, I am from Texas USA, and if you talk to me a while you will think I am from another planet due to my accent being so heavy.
Of course I am stoned as well, so I might be on another planet.
no dude…he was talking about his OTHER indoor very bright and hot garden…
I think I could manage a head banging conversation with you …I lived in LA from '75 until '81 and they really talk funny…my old deceased buddy came from East Texas , he was a writer and he went by the name of Max Crawford…time to grind some more Lights and do a mix of Moroccan Hashish and a big old pot of tea 
And who is stoned around here? LOL
I never touch the stuff.
Here’s a link to my thread: No Till Thread
You’ll have to scroll a bit to get to the current iteration. But it’s a 3’ by 6’ fabric raised bed - complete with worms, roly polys, and all the beneficial micro-beasties you could want.
I would think the cardboard would wick the water away from the soil and stay wet. Maybe they would be good to use as a starter pot for an outdoor grow. Instead of transplanting you could just put whole plant, pot and all in ground.
Hi Bud
thank you for replying , my concern was that the pots that are available here in Britain come from PRC (China) and I am a bit sceptical when the pack of pots tells me it is made from recycled material 
But !..Amazon will deliver Jiffys right to my front door up a goat track in western wales (on top of a mountain )…brilliant !
Stay warm
