New Grower How many plants should i put in this size tent

[Shrooms]

I'm a first time grower and just set up my tent... Dimensions: 120 x 60 x 170 cm (length x width x height)
I got a 600w hps and canna nutrients, I will be using 50/50 mix of perlite and soilless with 3 gallon airpots I also got a 10 pack of fastberry from fast buds I'm just not sure how many I should plant and if the 600w is overkill for this set up, I do have a dimmable ballast so I can drop it to 400w if needed...im ready to grow right now but i just don't want to waste seeds or growing media any help would be appreciated.

The 600 watt is plenty for that tent and the adjustable ballast helps. You picked a good strain and even a better breeder. With 3 gal pots I would do 3 and try that out and try for a SOG. Just remember height wise make sure you account for the distance that the light hood takes up which is somewhere around 10-12 inches so now you lose close to a foot and the height of the pots that's another foot so now your vertical is about 3.5. Fast Buds says it can reach up to 30" but nothing especially plants are guaranteed to be a certain size. I know all the height stuff is off topic but I wanted to just throw it out there.

I think two plants should be manageable in that setting.

Awesome! Keep us updated on the progress! Here you go welcome to AFN. Remember ask questions on anything and everything there are plenty of people that can help and want to help. I think you will do well just remember have a decent dehumidifier (when they are in flower) just in case. Oh,also head over to the live chat and introduce yourself.

In your case 2 plants and 600w is spot on. But HPS isn`t best bulb, check CMH or dual arc. HPS has crap spectrum.
