Nice, the blue dream I had from the dispensary tasted great and there buds were not really that great so I have a feeling these will taste fantastic!
I have used them in all the grows in my sig, almost a year now. I went with them over the smart pots since they are more reusable. Honestly I think all the root builders work pretty much the same as far as the root ball is concerned but I can say for sure these work exactly as advertised. After seeing how great the root ball is and how quickly they recover from repotting I wouldn't go back to normal pots
For the plants I want to keep smaller I go from keg cups into three gallon equivs then to 7gal for flowering. If I want them to get big I finish veg in 5s and then into the 15s for flowering. The blue dream this grow is in the 15 and the hurkle is in the 7.
