Best way to switch from 18 to 12 of light?
gottagrowsometimeanswered grow question 3y ago
Hi there
So, as you to into pre flower. You want the most even temp for the 1st few weeks (pre flower) so, I'd have lights come on at the coldest part of your day. And lights off at the hottest. Or whichever way gives you the least temp fluctuation

I’m trying to keep the midnight point when switching to 12/12 by giving the last day of veg several extra hours of darkness and the same amount on the first day of blooming. For example, if the midnight point was at 14:00 (no light from 11:00 till 17:00): the next day I switch off the lights at 8:00, and turn on at 20:00.

What would you do?I have 4 plants, two autos (one cream one tangerine dream) and two photo period (strawberry cough). I can put two in an indoor tent and the other two will go outside (all in fabric pots). What plants would you put where? Tent is small and can handle only two plants. Thanks!Plant. Other

Does my First Grow Look Healthy (Royal Dwarf Auto, Day 15))Hi, first time grower here, just wanted to ask if my 15 day Royal Dwarf is looking ok.
I had problems caused by overwatering and using too weak an LED in the first week.
I think it's looking good now after giving nutrients and pH balanced water.Plant. Other
