Plants possibly growing to tall..

Hi guys, i have 5 plants in a dr90 under 450w+ of CFL in airpots. coco & perlite 60/40%.

Over a month and a half old, switched to 12/12 2 days ago.

I can already see that they are to tall for CFLs but my problems is if i buy a HID with silverstar reflector that takes 30cm hight, then the 16-18inchs gap the plants need leaves no space for them to grow anymore..

What can i do? :/ Cheers for all help

I cant upload any pics for some reason.. ill keep trying in a comment

Just LST the tallest shoots down.

Each time they're getting too tall then use some more LST.


5 plants though is possibly a bit much for cfl.

I only grow 4x2.5ft tall plants under my 400w hps.

Yh I dont really have any space to lst.. im planning to get a 400w if I know ill have the space should I remove the smallest single cola plant? It'll be the second one ive had to remove

Will try posting pics again in an hour..
