Help with hash

This is my first grow. I have 6 autos. The smallest 2 I am harvesting tomorrow ( little cheese, pineapple express) I hope to get around 30 off the two together.

Will this provide enough trim to make a batch of hash?
Can I make one batch with multiple strains ?
i will harvest the other 4 two at a time over the next month. Can I accumulate all this trim and make one batch?

The remaining 4 are quite a bit larger like 4 and 5 feet.

you'll get a few hits of hash....not worth the work imo
fast freeze the fresh trim on a cookie sheet..then put into a bag....save till you have the others plants trimmings

You would need at least 28 g of trim to make 1-4 g of hash. Mixing strains is fine it will just round out your high! Just save up and do one nice batch.

JayBio420 is right on the money! The better the trim, the better the outcome.
