You can cut it back and use the cutting to make a new plant! I have to cut my Ventrata back ALL the time. Take a cutting with at least 4-5 leaves on it. Strip off the lower leaf and stick in in a peat/perlite mix. Bright light, keep the soil moist as usual. They are EASY to start this way.

The initiate pitcher growth first make sure it gets enough light. Then with a 1/4 strength orchid mix solution pour that onto the soil every 2-3 weeks until you see pitchers start. You can also spray that on the leaves as well.

Thanks a lot!! i would defiantly try it.
does that mean that i can take my 2.5 meter high plant with few dozens leafs and turn it into maybe 10 plants or would they die if they are cut from both up and down?

I did NOT say that!
