When switching to flower do you......

Put it straight under hps lights or mh for 2 weeks then to hps. I read about people flowering under mh for the first two weeks to reduce stretching. I've actually tried that once but I didn't get those results. My plant actually stretched more. Much more, I was growing sativa seeds full moon. I grow this with every crop since it's my favorite strain. Now that plant that flowered under mh gave me the best yield from that strain since I started growing it. The buds were really long and dense it actually seemed to produce more bc it stretched. I was going to do the whole flowering process under mh lights (bc I read about getting better quality but less yeild flowering under mh. Still don't know if that's true) but chickened out around week 4 and put it under hps bc the buds didn't seem to be getting bigger. Ended up with about 4 1/2 ounces dry. Which isn't bad for this strain. Ever since then I've been putting it directly under hps lights and they barely stretch at all when I put them up and I end up with about 2.5 - 3 ounces dry. Now what I'm wondering is if this was a fluke or if some strains actually produce better if they stretch a little more.

I like I think many do, just switch change the light schedule and away you go. People do all sorts of different things before changing to 12/12. Growers preference at the end of the day!

I have used hps since my plant came out the 2 week seedling stage before that it had a 45w led grow panel above it just to kick it off!

Also that one plant had like 4 colas and all the plants I grow now usually have around 6 - 14 colas. Does number of colas affect how much they stretch? Also what is the optimal amount of colas to have? I feel like the more colas you have the less amount of bud those individual colas produce. So would 8 colas be better than like 30 if you could do it? I grow in 5 gallon pots btw.

Ahh thanks for the replies I use a 175 watt mh for veg then when it's time to flower I move them upstairs to the 600 watt mh/hps. I also have a couple led lights I don't use. Don't remember the wattage I bought them so long ago. I'm definitely gonna throw them in when my new duct fan gets here. My last one just stopped working all of a sudden.

Sometimes it's better to replace things than trying to fix then!

I know nothing about electronics. Also before it stopped working I notice weird sputtering. I'm assumed the motor simply went out.

Definitely is grower's choice, personally when I flip I leave my MH bulb in for the first two weeks of flower. I think it stresses them less and allows them to adjust to the new light schedule before changing the bulb and switching up the spectrum on them.

Have not used MH in 10 years

Thanks for the reply. I think imma try this out again. I got good results last time.

Why not?

Full spectrum same spectrum through veg and flower like the sun. Use both mh and hps. Or just hps at the switch if you don't have 2 lights.

When you change lights, the plants go through a spectral transition which takes about a week. Which slows growth and delays onset of flowers.

So that's why you want the same spectrum through veg and flower. A full spectrum. The combination of se mh and se hps don't quite make an balanced spectrum like gavita de's or white led or induction or cmh.

So vegging with hps?? Have you found any significant differences compared to vegging with mh??

Have a hps light at the right height not too high above the plants this will do fine,Use what work's for you though.

Yes room is cooler for one as for growth rates same thing, As for stretching never seen it but i do crop my plants constantly to make, bushy trees.
For the spectrum difference which the new era of grower ??? that appears to be more concerned about and from my years of experience is a moot point
lets face it how many actually throw down seeds or clones and walk away never happens we train and do stuff to our plants
and many will claim that and its true MH will give you tighter internodes but the same theory applies with training with HPS
so with that all said MH for VEG HPS for flower rings hollow comes down to money grab i mean special ballasts to use both MH and HPS more money on Bulbs when all you really need is a HPS start to finish

That pic is actually making me consider trying topping again. I stopped a while ago bc I felt the same thing could be accomplished with lst'ing but maybe I'm wrong? Guess it depends on how long you veg also.

Thanks for answering. Ive heard similar from a couple others and with my setup now i was thinking of ditching the mh bulbs altogther and just running hps.

Youve helped me decide to go that way...

Ps: holy bushes batman those are some fine looking flowers!
