Using a 300W LED to replace shade (outdoor) hours

Hey, so I'm just entering the flowering stage with my first grow. The strain is unknown, as this plant was a free seed from a small batch of autos that didn't take. I've had the plant vegging outdoors since August 20th (late, I know. terribly new to this) in a 3-gal pot. It started pre-flowering maybe a week or two ago, and despite my lack of knowledge and expertise, the plant isn't looking bad at all. It gets about 4-5 of direct sunlight, and it's extremely healthy in terms of nutes and its size (about 2 ft untied, I have it LST'd well. Bushy.)

My question is, can I make up for the shade it sees for the rest of the day with a 300W LED? I've read that I need 6 hours of direct sunlight minimum for a decent harvest. But, it only gets sunlight from about 10 AM - 3PM, it sits in the shade from then on. Could I bring it inside and set it up under an LED for the remainder?

Obviously keeping it 12/12, would I benefit from this? Or should I simply make do with the scraps of indirect sunlight?

(Note): All of the standard outdoor to indoor precautions will be done religiously. ie: baths and sprays.

Where do you live in the world?
Deffinetly take her in.
Autos can grow under 24 hours a day, they need a minimum of 18/6 to thrive, u won't get a decent grow under 12/12.the more light you can give it the better.

You want to bring your plant indoors ASAP and get in under at least 300 watts of light 18 to 24 hours per day to make sure your buds grow big and powerful. I hope thats a 300 watt led. Get that light up close and personal to your plants. Start at 18 inches and slowly lower the light an inch at a time and make sure your plant is handling the extra exposure.

Other information provided here is somewhat inaccurate.

Your LED may seem brighter than the shade but you would be surprised. Even in a shaded area, during the day, diffused light from a blue-sky gives you approximately 20,000 lumens per square meter.

Most
"300 w" LEDs are actually 300w equivalent - meaning its probably more like half that wattage - and chances are it's more in the realm of 7000 lumens per square meter - but that depends on your specific light and how it's being advertised

You don't "need" 18/6 to grow Autos, and if someone is telling you otherwise, they must not have any experience growing these plants. Will you get a higher yield? Maybe, that really depends on the individual strain - and more importantly, the size of the plant - but one thing is for sure - it's not necessary. I have lost full-sun half way through outdoor grows many times on both autoflowering and non-autoflowering strains - it has never resulted in any drastic reduction in my yield or quality. I have, however, seen plenty of plants die, or nearly die, from having their environment altered too much and too quickly.

Plants follow the sun, the leaves will move towards the light and the stem will strengthen from that movement. Lighting is just one of multiple factors in total yield.

Changing a plants environment so drastically can also cause more stress to the plant than it needs. This is more true for moving indoor plants under direct sunlight, but applies the other way around, too. People really ought to stop treating Cannabis like its some type of special plant that has requirements different from that of any other crop. It will be fine where it is - its a plant.

like I asked "where do you live in the world" to nadhcra.
No reply.....
If he lives in America then light hours are different to the uk.
Put that in perspective before pipping up on who's write or wrong.
The U.K. Light hours and temp wouldn't be suitable for outdoor, so take the plant in.
If in America it all depends where you live I suppose.
U.K. Weather is sun and rain , sun then rain, as we know rain and moisture can create mould so I would bring in on rainy days or lower temps and put under 300w and they were fine, at 1 point they where kept in for 3weeks running as bad weather and they thrived..
