The soil you see with perlite is Lucky Dog K-9 and I mixed it with Baccto. The plants grew in just the Jiffy seed starting mix. This was the first time using K-9 and it's very light but it has big pieces of perlite and I have to sift it out. I will not use Baccto again, it's full of junk and I had to pick out sticks and large chunks of peat moss. I'll use MG moisture control mixed with the K-9.
