Early flower raising the lights higher for stretching

I've noticed a few strains I've grown over the years (maybe 20% of them) need to get taller to get a better yield. With that being said should I raise the light maybe 6 inches higher than normal the first week or 10 days of flower to achieve this?
 
No.

Raising a light reduces yield because the plant is receiving less light. Multiple researchers have documented that the more light you give a plant, the higher the yield. In addition to yield going up, plants that get high levels of light are shorter, they have more inflorescence, plant quality increases, and crop quality increases (the ratio of flower to total inflorescence increases).

Characteristics of plants that are not given enough light are that they will tend to stretch, they have larger internodal space, they will have reduced inflorescence, yield is reduced, and crop quality is reduced.

Light is one of three inputs that plants need for photosynthesis. If you reduce the amount of light that a plant receives, the rate of photosynthesis is reduced and the plant cannot grow as well as if it has more light (assuming that you have not reached the light saturation point and assuming that other factors are not inhibiting growth).
 
I know where you're coming from some stretch Isn't a bad thing, i've swamped to hps from mh in the past to encourage a little more stretch, more light will return more yeild but they don't need/want lots of light early in flower.

Observation... The buds we want all grow on new growth from after the flip so why not encourage it.

Also a bit space between buds isn't a bad thing either, super compact isn't a good trait imo.

Did you read his post at all?
 
Why not just veg them out a little longer? Stretching the plants is will give crappy internodal spacing as mentioned. Being able to utilize the full "goldilocks" zone of light is nice, but it's better if there are more bud sites. If you just have a top and a few lowers, the extra height isn't adding much aside from potentially burning the plants.

Good point, they are pretty tall usually. However this strain doesn't like light at all and the yield is garbage.
 
Taller plants doesn't mean more yield indoors...think about it. Outdoors, plants can be tall and it works out well because you have light all around the plant during parts of the day. Indoors you want to keep the canopy spread out (unless you're in a commercial grow with tall ceilings). I've done the whole "tall plant" thing indoors with 7 foot tall in flower, never doing that shit again lol.
