Measurements in ft.,thanks. Height as well.This is to calculate how much watts/sq ft.If you want to buy fancy lights , no scene, but I have similar results using a diy set up with regular led bulbs.aaron17 wrote:A typical room sizeaaron17 wrote:Cool thanks.timelapse wrote:I have lots of experience with indoor growing under artificial lights.Gimme an idea of the space you working with and what you want to grow.Then I'll give you a shopping list
Arite.On average, you gonna need 20-30 watts of actual bulb power/not equivalent power per square foot of plants in LED bulbs.For a barrel size, thats one 30 watt bulb,or 3x10 watt.Light requirements depends on the crops really ,so take that into consideration.I had Cannabis, pepper, tomato,mint,parsley grow at 30 watts per sq ft with success.aaron17 wrote:I wanna try something small first though...like a half ah barrel or something.

All depends on what you want to you may also need a timer for your bulbs.I got one at Bhagwansingh's for about $80tt.The bulbs, I bought at bright ideas.Bought some $8 surface mount light sockets, some wood, screws,electrical wire and tie straps and made my own lighting fixture.

Regular LED.Just break off the diffuser in a vice.It comes off easily.nervewrecker wrote:timelapse wrote:Arite.On average, you gonna need 20-30 watts of actual bulb power/not equivalent power per square foot of plants in LED bulbs.For a barrel size, thats one 30 watt bulb,or 3x10 watt.Light requirements depends on the crops really ,so take that into consideration.I had Cannabis, pepper, tomato,mint,parsley grow at 30 watts per sq ft with success.aaron17 wrote:I wanna try something small first though...like a half ah barrel or something.

What kinda lights you use?
One of my plant growing pardner bought some lights with heat sinks and needed fans to keep them cool.
Room used to get warm so he was considering an ac for it and carbon dioxide with a timer relay and solenoid to release CO2 in the room.
Apparently that's the setup the light skin boys use for their stuff. Plants grew fast.
5000K is more similar to morning or evening sunlight while 6500K mimics midday sunlight. In general, plants can survive within the color temperature range of 2700K-7000K, so both 5000K and 6500K are within an acceptable range.pugboy wrote:i thought the light has to have correct spectrum of colours

The bulbs I use are 6500 k.Watch the fine writing on the pic I put up.White light is full spectrum of colours.
I have one of those purple fancy lights.The only thing I use that for is to germinate seeds.Wasnt nearly enough light to make my cannabis have big buds.If you have the money for fancy lights, great,if you don't want to spend big money, you can diy with great results.
On the CO2 note, this is really good for plants, just don't keep it in your house.
It can raise your blood pressure, cause respiratory issues, headaches,etc.
I try a ting and it worked, based on my research, but neckbeards will neckbeard.The elite indoor growers may be deeply offended that my grow setup even exists and I don't have fancy lights and humidifier and all that other stuff.Dont take them on, they get caught up with the sales pitch.

For cannabis, it kinda is a balance.Bluer light keeps plants short, while encouraging more branch nodes.Redder light gives lengthier branches and bigger buds.I didn't see the point in having to switch up lights, especially as I have different types plants at different stages of growth in the same grow room .I have it on a 12/12 timer which works for multiple crops.That and it much cheaper.adnj wrote:maj. tom wrote:

Valid. But this is not a representative spectral curve for all LED white light.timelapse wrote:Graphs don't grow plants dan.I have an expensive grow light which is based on those figures.There was zero difference between that and my diy setup, which was cheaper, and price enabled me to build it on a bigger scale than the ready-built one,increasing my plant capacity.While the middle spectrum of light is wasted, nobody cares really,power consumption is around the same, no love lost.

That's not the point. You can hang anything up and it will be useful to the plant.
You focusing on 6500K is wrong. Midday sun is 5500K. It is likely that your plants will benefit from an even higher red shift to 3500K so that they can absorb more near infrared. Mixing color temperature can yield results similar to mixing LED frequency if you lack the background or equipment for actual measurement.
If you look at the color spectrum you can compare 6500k and 3500K white LEDs.timelapse wrote:Here's a study of all that since we nerding out..
https://www.producegrower.com/article/production-leds-on-lettuce-white-light-versus-red-blue-light/
My take home: A red/blue light that will deliver any kind of substantial growth costs way more than a full spectrum diy setup.
Sorry boy Aaron, like we taking the fun out of this thing.If you going ahead with it, let us know how it goes.
