Autoflower help

Can I grow lowgirls under T-5 6400k (grow) throughout entire grow for 20/4 or do I need to switch to 3000k( bloom ) at first sign of buds and go 12/12? Thanks all

You could stick with the 6500k thruout the grow but your yield will be down anything upto 50-60% I think, T5 tubes ar elike £5 so I would defiently get some come flowering, If its a 8 tube maybe leave 1 or 2 blue tubes in and have 6-7 red, a little blue light in flowering is good to help with stretch but the majority should be red.

Thanks for the reply. But I should stay 20/4 or go on to 12/12 like a normal plant?

keep it at 20/4 thruout the whole grow.

Thanks john.

i run mine 400 watt hps at 24/0 and they are growing fine growing 7 in a cabinet

I got a freebie from Attitude, RoadRunner, that was my first auto-flowerer. I know you are supposed to
keep the lights at 20/4 for the short life of the plant. But I had another dozen indicas going in the same room.
So my RR got 35 days of 20/4 under my 1000W. set-up and then 35 days with the lights back to 12/12. The
auto-flowerer did great! I was so pleased I ordered a batch of the RoadRunner for my next grow. I'm
going to raise them the same way -- 5 weeks of 20/4 then 5 weeks at 12/12.

Thats what I finally had to do 12/12 on HPS. They seem to be doing ok.
