Timing Is Everything.
In the past the there has been pros and cons of growing at night.
Pro: lower outside temperature, easier too cool.
Con: easier for the infer red sensors to pickup.
Now growing with LED we need not to worry about either.
So I tried to think up of the best light schedule that need not apply to the old standards, but to my "stealthy" standards.
Keeping quiet is important for a stealthy grow, having your system off while visitors are around is a good way to achieve that.
Here's what I came up with. IMO most landlords, gas men, Verizon guys, electric Co's, po-po, friends, mail lady, UPS guys, and more
come to your house from 10 am to about 6 pm.
Now, as a stealth grower your best means of productivity is to have a flower and veg area separate. You will need at least 16Hrs for a Veg area and 12Hrs for a flower area. Heat is not really an issue but venting for fresh air is needed at least every 30 min IMO. So even the noise of a vent is a bit of a pain in a quiet house.
WHAT TO DO:
Start both areas at 5:30PM
Then don't' start your first 15 min burst of venting until 6:00PM
Now end your flowering area at 5:30AM and Veg area at 9:30AM
Shut off all venting at 9:00AM the heat that builds unti 9:30AM will cool when the lights go out + plant breath less at night. "thier night"
Now if you need to go for 24 hours or something it should only be for a few weeks if that, per grow. Also if you vent less or your room is colder you can hold off the fans even longer in the initial startup of both light cycles and maybe even the ending of the veg.
If you feel you can hold back your first venting, adjust the hole timing setup to that for an earlier shutoff.
For example: If you can have your light on for an hour before you must vent then you can start it all at 5:00PM and still turn you first venting on at 6:00PM. But now you can end the Veg cycle at 9:00AM so you last venting would be at 8:30AM, thats an even bigger silent window. Still with me?
