Waximus, I don't think ill be able to fit both lights in this small tent, do you recommend just using the 500 the whole grow? And my local shop recommended 24 hour lights all time? What do you all recommend?
Hey Haze, have you seen this thread?
Thread: What's the best lighting cycle for autos - 24/0, 20/4 or 18/6
It's a running poll of what members on the forum have voted on for what they think the best light cycle is; might give you a little insight on at least how others feel about it (and you can see their names on the polls, which means you can click on their profile, check their grows, and see for yourself what they are getting with those light schedules.)
In my opinion brother, you can grow excellent herb in any of those light cycles. There is a reason a majority of auto growers stick with them; they are tried and true. I think you would be better served not trying to decide which is the best light cycle out of the three in general, but which is going to be the best light cycle for you based on your strains and your environment.
I mention strains because sometimes (this isn't incredibly common but something to point out,) you'll get a phenotype of a strain that is possibly more light sensitive than others; which requires more of a dark period to begin flowering. I've personally encountered this with three different strains (three different reputable breeders.) This can be counteracted by reducing the amount of "lights on" time.
I have some tester auto beans on 18/6 right now that out of two seeds of each strain, one is flowering on 18/6 and the other is still in veg with no preflowers (nearing 90 days! (they are testers though, so that may not be a real fair example, but wanted to point out how it can happen based on the genetic line.))
I also mention environment; in the last house I lived in we had VERY cold, frigid winters. Like, 65 below zero Fahrenheit wind chills. I was finding out that in my basement at the time, when it was lights out, the tent cooled down a LOT. I could sit there and monkey with heaters and ventilation and worry about additional fire hazards, or keep my lights on 24 hours and not have to worry about the temperature fluctuation or additional venting considerations. That was with HPS/MH though, with your LED's that's a bit of a different situation.
Point is, don't get caught up in the idea that ONE way is the only way to do some things. I definitely encourage you to pick one of the three conventional lighting schedules to start out and see if you noticed any difference between them as you begin to grow, then if you are feeling bold, try another and see if you observe any differences.
Good luck brother! :Sharing One:
