Smart pots AREN'T! Their JUNK!
Smart pots air prune and create a root ball massed in a block away from the walls of the pot... This creates the "umbrella effect" mentioned earlier!
You pour the water/feed in and it simply runs out the sides while not effectively getting the root ball wet! You either let the pot sit in the run off - not good, or keep pouring your run off back through - I have better things to do, or pour more through and waste expensive nutrients.....
I tested these damn things for a well know maker before they released them.....I told them what I thought of them. naturally, they did not use any of my feedback in their advertising.....Hunh, wonder why?
Plant Warrior pots are NICE! I went back to the normal everyday inexpensive plastic regulars...
Besides, use a Kelp extract and any pot is better (other then those cloth hats)
Get at least 1 - & gallon and run that beside a 5 and see what you get......
