T8 cannabis grow

4′ 4 bulb t5 i think is definitely overkill for you.
i mean it is always nice to plan for future upgrades.. but i think that’s too much for an unventilated closet that’s just for babies.

We’ll see. I just need to buy something now and then. After all, it is a hobby.

However, if heat is not an issue, I could see upgrading.

yes T5’s get warmer than regular shop light flouro’s.
not like going to hid, but they do kick some heat.

Would a 2 bulb 4 foot be enough (at least equal to the 2 shop lights)?

For flowering, you really want HPS, or if you’re rich, LED COBs

after you figure out how much you smoke in a day times that by 2and a half months
this number is what yoy need to griw to stay self sufficient

make sense so far?

Thanks. The "lightbulbs" at Home Depot use XT or XB diodes. The later have been used to grow without additional light (i.e., not merely supplement), yeilding >1g/w. The lights you linked to are SMD5730. I’d like to learn more about how the SMD compares to XT (efficiency, spectral curve). Has that been discussed anywhere?

t8s are ok for cloners and seedlings
I say ok just cause they dont have much intensity
which means you must keep the light as close as possible without hurting the plant.
and training if yoy dont youll have lanky plants

an 8 bulb t5 in my hands can yeild over a 1/2 pound
Your results will vary

IMO, it’s not so much that your grows turned out great, but how many grams per watt you got. How many watts per sq. ft. you used, grams per sq. ft. It’s about efficiency, I believe. The cost of space and electricity.

This specially designed 517nm-525nm Green color LED allows plants to remain undisturbed in their dark/sleep cycle while the workers can still see to work in the grow facilities.
The Green color LED is also germ retardant keeping germs and bacteria from receiving any life-supporting normal full-color spectrum light. This helps keep Pharmaceutical facilities germ-free. They cannot survive in the green light.

Dream of Big Yields and Work while Plants Sleep in their dark cycle with ASE LED Work Lights!
ASE LED Sleep Lights are Green T8 Tubes and a straight replacement for old fluorescent T8s work lights. The special green color (517-525nm) allows you to enter your grow room to work without disrupting your plants’ natural sleep cycle. They come ready to go and fit right into a T8 fixture.

UL Type A + Type B listed. This T8 LED directly replaces traditional fluorescent lamps without making any changes to the fixture or wiring. It will also work without any ballast using direct Line power to a single-end (ballast bypass).

Good Retrofit Choice

These Green T8 lights have also proven to be very useful for photography green screen production.

Oval tube made of half aluminum and half PC lens allowing excellent heat dissipation.
