I dont have any links but it would be the same as any other perpetual grow. Instead of taking clones with X amount of days until the flowering plants finish, you would just plant seeds X amount of days before the flowering plants finish. So any perpetual grow journal should work. Although, id stay away from perpetual. Personally it gets annoying mixing up 6-8 sometimes 10 gallons of nutes and pH'ing it all. I started out with perpetual because i thought itd be cool to harvest more often, but soon realized it was alot more unnecessary work for no real increase in anything. I get the same, if not better yield from the 2 month cycle since it gives me more time to grow out the veg and top/train to my liking while using that time instead of waiting for something to get to a certain point.
But thats just me. If youve got the time go for it. But let me know what you think of it. haha.
