hi ive got a northern lights she was started off from seed with HPS 12/12 then i got 250w cfl kit at week 6 changed over to veg light 24/0 there was no problems. i put the flowering cfl in 30 days ago but now shes too tall ive had her tied up what a mess she looks can i change back to the 400w HPS its higher up about 1foot away she'll have more room to grow hopefully that might fix her? shes got about 6 weeks of flowering left. this is what she looked like under CFL she didnt look happy all tied up so i've untied her put the HPS back on.. this is her now under HPS shes got more room to grow but what a mess im hoping hps helps her out?
strains will stretch for the first 2-3 weeks of flower...some stretches 3 times its height...and each strain is different. After that vertical height growth is at a minimum... Yea man, go ahead and give her that 400w HPS goodness. if you can keep temps down why not give them both lights? just a thought...
