Cool. Regardless of your claims, it's still not recommended to mix manufacturers...for reasons previously stated.

the plant was showing signs of needing repotted. she's in a 12inch square planter and it would be nice to get her into some fresh soil.
Once established in veg...I try not to mess with the roots if possible. How about a transplant into a 14" container, or are 5 gallon pots too large for your situation?

If truly necessary, trimming the roots is acceptable, but it will result in a stunted plant that takes forever to 'catch-up'. (can take three weeks or more to recover from the mid-cycle root-assault)
