Sure do some autos that the same time,....
as many tomatoes strains are considerably
weaker than cannabis autos ...so any bugs will be attracted to the toms
good luck

OPTIMAL PHOTOPERIODS
"For tomato, best growth and yield were obtained under a photoperiod of 14 hours (V�zina et al., 1991; Demers et al., 1998b). Photoperiods longer than 14 h did not further increase yield. Photoperiods of 20 and 24 h can even decrease yield and caused leaf chlorosis (after 6 to 8 weeks) (V�zina et al., 1991; Demers et al., 1998b). Although long term use of a 17-h photoperiod does not increase growth and yield compared to 14 h, it might be interesting to extend the photoperiod to 17 h in order to increase total light provided to plants especially during the months with the lowest natural light levels (December-January). However, if a 17-h photoperiod is used, it is important that the dark period be uninterrupted, since splitting the dark period of 7 h in two short nights of 3.5 h (separated by a light period of 4 h) caused leaf chlorosis and decreased growth and yield (V�zina et al., 1991)."

I grow tomatoes indoors every winter along with my girls. They seem to do fine under 18/6 so they work great with autos!! Look for dwarf varieties as other ones tend to get too big (IMHO), since dwarf varieties tend to be "determinate" I find I have the best results if I stagger the planting by a couple weeks so I'll have a continuous supply of 'maters.

will they not flower untill you flip them to 14/10?

14/10 should be the minimum light required. Tomato's will flower @ 16/8 just fine. I'm testing the hydro setup and growing in a controlled environment because I have abnormal plans (lol). I'm only trying to grow one tomato and I'm growing for size only. I normally grow in soil that is jacked up for extreme gardening. I grow giant pumpkins and have a desire to grow the first 10 pound tomato. I'm just wondering if I can use hydro to control the nutes to my advantage.

It all starts with good seed, soil & luck. Going after a new record it wouldn't hurt to have a nice megabloom to boot.just make it happy then only let it set one fruit .... but im sure you know this already

This is very true, tho 14 hours is ideal for tomatoes, no apparent damage to the plant is done at the 18/6 which is ideal for cannabis in veg or with auto flowers,
should the grower get a great crop of tomatoes with the autos, do keep some tomatoes seeds aside, as with cannabis seeds(or any plant) temperate climate data, and nute desirability is printed into the seeds DNA, making the next crop a lot easier to germ and grow!
