Lighting for auto flowering plant grown in tents

Does it matter how high the light is in a grow tent for Auto Flower plants

Hi @Ajp420 yes it does, keeping the light as close as you can will make her bush out and if the light is too high she will get lanky…also will affect the bud that grows …


@retiredoldguy is right you can use your hand if it to hot for your hand it’s to hot for plants @Ajp420 that’s old school way what kind of lights are you useing

Absolutely it matters. It matters enough that one should pay attention when selecting a tent. Too short a tent is a headache. Also pay attention when selecting strains. Some are known to grow taller than others.

As to light height above the canopy, it will depend on the type of light you have. The light source, LED VS HID VS CFL…… as well as wattage which helps understand the light output.

One example is the light I’m using. Spider Farmer sf1000, as directed below.
You’ll note this light has a dimmer as well, another factor when lighting up plants.

Even with the plant being an auto flowering plant

I would say more so with autoflowers. You cannot correct a problem w a longer veggatative cycle like one can with photos. If they miss the sweet spot early on you will just have lil tiny lollipop plants that stop vegetating up. They will just be lil buds on a stick stem. The smoke will still be good but the yield will leave you longing for more.

The ease of autos is in short season outdoor growers. Plant and don’t worry about it for 90-100days or so. The buds finish in the summer window. Indoor the time saved is the biggest advantage not having to run a dedicated veg cycle before flower. I have only run autos 3 times so I am no expert. But I would say the auto flower crosses with photos have been improving greatly each year as far ease growing (forgiveness for minor problems) and yield.

There are many here on this site that have way more experience than me with autos. As a matter of fact everyone here has convinced me to try some Frankenstein autos this next season outdoor. I will try to do a good grow journal of its progress. Then I will give you my honest opinion after I try those…

Welcome to the site @Ajp420 alan parks. Happy growing.

As they say, it’s not the height that matters. It’s the intensity of the photon flux density. :crazy_face:

@Ajp420 yes even being auto flower…indoors lighting is sooooo important so this is definitely an area where you buy the best you can and get it as close as you can

Is it better to use 5 gallon pots or 3 gallon pots… for Autoflower?..:stuck_out_tongue_winking_eye::camera_flash::clinking_glasses::milky_way:

Hi @BAZOOKA the bigger the pot container typically means a bigger root ball which translates to a bigger plant…

Thanks…I will try out the 5 gallon… this is my first auto flower…I going to grow 1 plant… Organically…I choose the Sour Diesel Auto… Thanks for the input…:stuck_out_tongue_winking_eye::camera_flash::clinking_glasses::milky_way:

@BAZOOKA do you have good overhead space to grow and your light…the top of your plant could get to 36 inch from the floor in a 5 gal

I just harvested a single plant auto grow. In a 27 inch square, five foot tall tent, it definitely benefits from a five gal grow bag. The bigger pot, with a whole bag of soil, ends up shallower than the same bag of soil in a narrower three gallon pot. So it buys root and nutrient capacity, and a little extra distance under the light.
