a mh/hps question

So I started a lighting cycle of 4 weeks of mh flower and finish off the rest of flower to hps.....since mh keeps the strech down will going into hps on week 5 cause alot of strech or sinve the first part of flower is done there wont be much?

Your grow is not well described. MH and HPS both have their benefits and disadvantages so give us more info on your grow and we can fine tune for your issue.

I think they might only fill in, I did that once but it was because my hps bulb burned out , long story short, I got the replacement at around week 6 and for the last 4 weeks they just gained lots of weight ! But that could be just my case/strain yours might be different , I'd say don't knock it till you try it! Let us all know what happens !

The stretch should be over by now. So you're good to put the hps in. Normally you don't go 4 weeks with the mh. A long time ago I was taught to have the mh in for the 1st 2 weeks then go hps for most of flowering and then put the mh back in for the last 2 weeks to help ripen it up

Its going 4 weeks because I have my blueberry in the hps wrapping up...I have a strawberry short cake in the mh right now with a shit ton of resin on the buds

Once I make that transfer I have a pineapple chunk that has to go into flower
