Scrog help!

Hey I'm wondering how many plants I should scrog up in my 5x3x6 tent this will be my 1st scrog. I'm growing under a 600w with advanced nutrents and the strain is blueberry. I topped them once and am using lst. they are In 3 gallon pots using pro mix hp. I was thinking net at 8 inches and only three plants in 5 gallon pots. any info an opions would be appreciated. thanks.

looking good it really depends on the final size,,or the duration of flower,,I can fill a small area with many plants or just a few and take up same room,,I do a slow grow or try to lots of fimming and lst and super cropping,,I try to make 10-30 kola's ,,you said this is your first time scrog grow ,,the rule of thimb is if you put them in flower at 12 inches they will finish at 18-20 inches can be more depending on the strain,,and where it typcily finishes ,,or can be effected buy the size you have to grow in,,Is the Blie berrie a heavy sativa,,or a heavy indaca ,,or a Hybrid,, here is a break down for strain is pretty close,,

Here is the equation for indica strains. The vegged plant height (V) multiplied by 1.5 equals the plant height at harvest (H) or 1.5V = H If put in flower at 12 inches finish around 20 inches can be little more

Here is the equation for sativa strains. The vegged plant height (V) multiplied by 2.5 equals the plant height at harvest (H) or 2.5V = H. ,,put in flower at 1 foot can reach 3 foot buy finish or bigger

Here is the equation for hybrid strains. The vegged plant height (V) multiplied by 2 equals the plant height at harvest (H) or 2V = H. if put in flower at 1 foot will finish around 2 foot

here is a link they should help with any info

It's best to use fewer plants and train/trim/fim/top/etc so they spread and the canopy stays flat. if you do too many they crowd each other causing all kinds of problems. in that space you could try a vertical trellis, doing it normal two full grown plants max

Go vertical! You won't look back

I would say 2 plants, 3 tops. It also depends on how long you are planning on growing them in veg. You dont want the plants to overcrowd each other in the SCROG.
