How much will I yield from this setup?

everyone will tell you that this is the most annoying question there is. only way to know for sure is to do it and see.. strains matter but not as much as ur light. u need 1000w light for a lb so with 2 600s u should be able to pull a lb if u take care of it properly

yea I know but I was hoping someone that has done a similar grow with experience could give me an estimate

every grow is different.. even for the same grower.. just depends on the specific conditions YOU give ur set up. anywhere from half a gram to a whole gram per watt

probably going to produce a shit load of heat in that small space on hotter days depending where you live. hopefully you will have powerful enough venting. i would def go with cool tubes also.

This is a very general answer and wrong. You can pull a lb from a 400 or 600 if your a decent grower. Which strain you pick will determine whether its possible or not. Ive pulled a lb from autos using a 600, they finished in 60 days.

Why are worried about your yield ? You first need to worry about keeping them alive and growing. Worry about a good healthy grow and the yield will follow.

I am going to have 18 plants strains: afghan kush, blue dream, GDP, green crack, kushberry, and strawberry cough (all 8-9 week flowering time). Im going to be picking them up when they are all about 3-4 weeks old and then be putting them straight into flowering. They will be in either 3-4 gallon buckets with fox farms ocean forest and will be using big/tiger bloom for nutes. These are the important factors for the yield since I dint think that the specs on my ventilation ect would really make a huge impact. Thanks for the input everybody

Maynard G. Krebs has it right - yield is less important than all the details you have to wade through.
Worry about lights and watering first.

Having said that, you are going to be pinched for space bro'. I realize that the 2 x 600W set-up is
preferrable to the usual single 1000W light for coverage. However, 18 plants is a bunch in a 5 x 8 foot room.
I would flip them now if you can because of stretching. The plants will still grow during flowering,
especially if you switch now. Any way you look at it you will be pressed for space.

Good luck, BigSteve.

i couldnt agree more. i would do 4 plants under each light. You would probably get about the same yield as you would with all 18 and it will be less work to start off with.
