Curious how much time left?

[BeatrixKiddo98]

So I have several plants in different stages, but they’re all on 12/12 and have been for about a month, maybe 5 weeks. Does anyone have any estimates on how much longer I have? I’m moving in October and I’m thinking they’ll almost all definitely be done by September, including drying. Hoping I guess. Thank you in advance!

End of September at very latest imo taking into account the ones not flowering yet.

Hi Beatrix,


they are only halfway there... if you need to harvest sooner, there are a few factors/ techniques which can influence this a bit:
- Nitrogen depletion
- More red light spectrum + FR IR
- Far Red EOD
- Gas Lantern Routine bloom lighting timers (gradually reduce daytime length) AND/OR
- keep nights always longer than days

In practical terms:
- stop feeding (soil) or reduce EC (soilless)
- set timers to 11/13 then reduce by half an hour each week
- add HPS to your setup

how are your ambient temps during day & night?

Looking good so far

Thank you! Ambient temps are mid-60’s at night and 80-90 during the day

mid-60’s

ok this is far too low and actually will decrease a plants' metabolism. should be, at least 75, for optimal growth. what's good to use are heat maps under the pots for the roots and IR lamps because they better heat up the leaves. depend a bit on your setup though, in a somewhat closed or semi-closed aircircuit you coulöd just use a conventional heater.

Perfect temps, except 90 is pushing the envelope.
No issues with 65, but above 90 heat stress will become an issue.
Also figure on 9 weeks until finish.
Sweet looking plants.
Nice job
