Best time For clones outside?

Whens the best time to put clones outside without them flowering? I put some out in april 20 and they flowered i live in northern Cali dont want them to flower then reveg big waste of time thanks seeds just stress me out bad luck bugs always eat
them!!!

For us in Oregon..Now-June 1. Transition them outdoors..I had some from a a friend and fucked up by not asking him what kind of lights he had them under..I think it must have been 40 watt light bulbs at light 5 feet away, because they got the shit burnt out of them. They are starting to recover. But undoubtedly stunted thier growth.

Well it all depends on your location and how many hours of sunlight you get. Also the light schedule of the clones is important to. I live way further north than you and I have a few outside that are going strong. Google your amount of daylight for your area. I wouldn't put them out with less than 15 hours of daylight. Mine were in a 18/6 schedule and were put out when we got 15/9 light schedule and they aren't flowering. My buddy planted on July 1 last year and pulled over 3.5lb with 5 plants

It also depends on what you have your lights on....if you have them on 24/0 and put them out they will probably still flower....
If you have them on a more natural light schedule you should be fine to put them out now...
I put mine out on 4-20 too....but I use supplemental lighting...What strain?
