That first dose of food thing is similar to the Biobizz Light. i have heard peol;e say that Coco Loco is like soil in that way.Honestly I'd check both places and see if they have the Seventy Thirty, but you could definitely use the Coco Loco. I'd imagine the amendments in it will only last the first 2 weeks if you're watering to runoff, so just take it slow on the nutes at first. Their Ocean Forest soil really worked well for me, so I wanted to try their coco since it's local and much easier to go and grab.
