Very nice thread, Lots of nice root pr0n going on.
Here is a World of Seeds Strawberry Blue in a 0.4gallon pot for 1 week after being repotted from a 0.5L pot, Spent about 30 days in the 0.5L pot and then another 7 - 10 days in the 0.4g pot. The roots push the coco above the pot, amazing.
I used beneficial fungi and Nitrozyme, thats how i got the roots so dense in the above pics.
Dose Nitrozyme everyweek in veg, and 1 - 2 days before dosing with Nitrozyme, water with bennies and see how the plants react, its like they are on roids.
