Hello all! So I finally ordered all of my grow hardware from amazon (600w hps/MH ballast with reflective hood and bulbs, 5 bricks of Coco, Perlite, Worm castings and Jacks classic nutes. My question is, I just ordered seeds from Nirvana and I saw for the first time the soil and flower tabs. These look really interesting and easy to use. I don't want to mess up my first grow because the seeds were expensive! I decided on the fem Blue Mystic and fem Aurora. Are the soil tabs and flower tabs safe for coco? Is it recommended? A side question - I plan on using a mix of 50% coco, 25% Perlite and 25% Worm castings. Is this a good mix ratio? Anything you'd do different?
