Hydroponic enthusiasts lend me your ears...is a skylight window enough to grow underground?

no

Skylight..even 12x12 would be enough to read a book

Will be an epic fail

you need an east west A-frame skylight otherwise the angle of light would only be in the high noon.the A-frame will dampen high noon temps in the garden.
that has nothing to do with hydroponics dude.

your plants aren't reading a book.

they may grow but they will be extremely wimpy plants and fruit veg yield will be very low if non existent.

Well could someone suggest the minimum size skylight for a sunken room 12ftx12ft

You going to say...12ftx12ft skylight?

A frame is your best bet to capture the most angled morning/afternoon light.

Would not be optimal, but it would work.

If you think its going to be stealthier underground you are wrong.

Not at all the most proficient. Just get a HPS for bloom, and a T18 florescent for veg.

every state now has sattelites if you growing others.but thats not probable cause.
stench is not either as hogweed and shirazi tobacco both stink.but cops dont care about laws,they care about cheating and smokin dank they stole from others.

If i must use electrical i would be after the most efficient. You think floresant be better than LEDs?
I am also thinking of powering it all with a single solar panel wired directly to tje light without the use of battery

Sounds as though i dont much know what im doing. Your right. Thats why im asking questions

Depend s what you’re growing. Veges, fruit, cannabis- no. Flowers-
Maybe. Vine plants-yes


You will need fresh air or mold will form.

You saying with a 15x15 skylight i could grow vineplants the likes of Cucumbers, squash, peas, pole beans, tomatoes and sweet potatoes are some of the most common vining vegetables

??

Oh and thanks for the need for air. Didnt think about mould

wattage equals yield,no way around it.
smart meters snitch,fact.

fiberglass roof panels,charcaol air filter,solar duct fan set with themometer.85°f.

You're lightyears from being able to pull this off.

almost no green house is totally sealed,by using a duct fan,you get negative pressure and ventilation.
the higher the A-frame,the longer the growing season.

Never used LEDs personally other than with orchids and succulents, but energy wise yes they're more proficient and can even be used for blooming if I remember correctly. They were a new option years ago and we quit growing before we could try them. They offer specific light spectrums too which can be beneficial. Look into the LEDs for sure. Solar panel is a good idea.

Also if what you're growing can get stinky, look into a carbon filter. It will be necessary.....

Hmmm...fibreglass opaque lets a lot light in

And this...dehumidifier, air purifier, and a simple fan to move air around. If the space has no accessable fresh airflow then that's a tough one.

No.
Get led grow lights from a reputable manufacturer.

dont waste your time,go to htgs on the www and buy the 150$ 400 hps setup with the mh bulb extra.this way if your starter wears out you can pop in the mh until you get new starter.

you are talking to a pro bro.
new bulbs are 20bux at home depot.about every five years.
skip the bullshit,you aint got time to play games.

if you got extra cash,get the cloth pots.20 gallon.dont fuck around,3 of them.
plus a 10 bux 3 prong timer from home depot.

opaque is more even distrubution.plus cant be seen in,charcoal inside filter kills all odors,solar powered kills the electric bill.

but read my other post.quit reading and just do it.fuck led!

400 watt should do.

An old article claimed it might be possible to grow plants with no light and no batteries or input. I explain the theory and how it can be tested.

Youll be on the feds list buying grow lights online or even hps bulbs from HD. Unless you want your home regularly xrayed and your mind/body harassed with electronic surveillance tech id just grow smaller amounts with flourescent.

horse shit,feds aint shit,tv boogiemen.
400 hps is same as ac unit.less than oven or microwave.they cant xray shit or thats assault.need a backstop plate and other stuff,you can grow tomatoes all day long under hps and they cant say shit.to above,fuck you!

tomatoes indoors is year round top end food,throw in some flowers for winter cheer me up and some cukes for salads.in the side holes grow radishes and carrots.on the extra floor space grow cantelopes.

fuck the feds!
robo waves!

My conclusion so far is skylights plus an additional electric light

Which kind of ligbt i dont know

Lets say we got a pitch black room and it takes 500watts
To make vine plants to grow well

If i put in 2 skylights 15inch by 15 inch...in effect 30x30

My guess is i will only need 100watts to make those plants grow

There is an army of them well funded by unlimited magically printed fed dollars fighting the "war on drugs" they can and do xray, amongst other even worse forms of electronic surveillance. its not assault in their eyes and they get away with it because everything they do is under secrecy orders. You are a dangerous enemy manufacturing drugs according to them and they will do everything in their power to mind control you into submission or in prison.

Your idea is not worth the effort.
The distance, angles, and glass matter.
Wattage of flux will be negligible, far away, with modern double panes, and at oblique angles.
You want photoperiod control anyways.
