Question Gordo. With your wealth of experience with autos, would you say that 24/0 is preferable over any other light schedule? I've only grown autos so far (one at a time), and was curious if I would speed things up or increase yields with lights on all the time, or stick to my 20/4 schedule. So far I've been quite pleased with my harvests, but who wouldn't want something better. Thanks! 🌸​​​​​
Thats a great question, and thanks for the compliment. As for as light schedules go,, thats a very subjective subject. Ive read that 18/6 or 20/4 is best for auto.. i dont know how someone came up with that figure considering that different seeds from the same mother will grow so different from each other even under the same conditions, it would be difficult to say one light schedule is better than any other when it comes to auto. Of course i could be totally wrong about that,, but I haven't seen anything scientific to the contrary. What i do know from my growing experience is that the more light time you give a plant the bigger it will get especially during flowering.
When i say bigger, i dont mean taller.. i mean better stem and leaf growth, more and bigger flowers, more yield, heavier, tighter and better smoking buds.
all that being said,, i personaly like to have my lights on 24/0. Ive only been doing that for the last two grows but i see a difference from when i use to do 18/6.
again, that depends a lot on pot size, nutrients, and strain. But it seems logical to me that more light = better grow.
Also i put the girls outside during the day to get even more light from mother sun.
now, anyone that has some information that 18/6 works better, please jump on in here and tell us about it. I'm alway open to other opinions.
Pot size: when it comes to pots,, size does matter. I've grown a lot of autos in 2 gal air pots (more like 1 gal if you ask me) thinking "it's only going to be in there for 70-90 days, how much root can it grow" well i was wrong about that. The roots of an auto will more than fill a 2 gal pot in less that 65 days. If it's in a fabric pot, it will fill the pot with a massive root ball well before harvest. Now 3 gal is the smallest pot i use and even that might be on the too small size. I dont think 5 gal would be TOO big.
I just dont have room in my tent for 5gal pots. But if i was going to grow only one plant at a time, i would try a 5 gal pot. What have you got to lose?
