I recently made a little discovery/had an epiphany about scheduling in perpetual grows; first, it's not news to suggest that running just one strain per batch is desirable- but how to coordinate a veg and two rooms with differing strains, especially if they have significantly different flowering times?
I run a four way perpetual, so staying on schedule is a must. Since every room gets 64 days, it came to me that if one strain needs all of them and another only needs 55, then why not run a veg schedule for the short cycle variety for a week or 8 days- this would let them become massive and take full advantage of their short finish time. Most short cycle strains don't stretch much, so this approach would essentially create a stretch phase where none existed before, if my thinking is correct.
This tactic seems to offer benefits over running as usual and chopping them on time, as just letting the room sit dark for a week seems unproductive. The only issue I can see is that with a veg cycle, the room would be using power when it's ordinarily dark, and thus is adding a load to the other half of the flip schedule. I have the headroom, but this certainly could be a concern for those running without much excess capacity.
