I've been using a couple of these for a few years now. They fit perfectly in the mini-greenhouses I use. They seem to work fine for microgreens and seedlings. I tend to leave the light on the red+blue setting rather than just red or blue.

How viable your seed is can depend a bit on what it is and how it was stored. Some seed tends to have best germination in a year, some can be more four to five years. There's a lot of lists out there for seed viability. If you are unsure of your seeds, you can do a sprout test before setting up your pots. You might find you have good germination to poor.

Depends on your growing room/rack/shelf space. I have a downstairs 'project' room with a big counter depth work surface and a half dozen wide shelves for garden seed starting.

My year round micros are just off the kitchen in my pantry. Two 9x35inch shelves. Right now i'm just growing 4 trays that fit in one small 9'' by 12''. Keep it simple. I like my micros in my face where i can keep an eye on them. Lights on a timer--5pm to 7am. Strip lights like you posted.

Nice light early am where my coffee grinder is located. Nice to see green plants all winter. Easy to give a 5 second check on them. They need a peek once/twice a day. Day 5-6 they get thirsty.

One friend still growing in a small NYC apartment cleared a 10x24inch shelf in her kitchen. She grows 4-6 trays on one end and uses the rest for starting a new starter stack and supplies. Nice night light.

She has four strips like your link but just uses two. I'm just using one shelf now--so four strip lights.

My lower second shelf has seeds and supplies now. Takes about ten-15 minutes every two weeks to start 5-6 small trays having supplies handy. If i start 8-10 trays i get way ahead of myself but cut fresh they last nearly two weeks in the fridge in a bag with a dry p-towel.

Keeping it simple is growing the fast growers. Peas, radishes, cabages, sunflower.

I'm still using seed from 2019-2020. I think my sunflower seeds are from 2016 or earlier and no longer viable. I buy bulk and have about a half a pound of my 8 or so favorites in the freezer. But the big crate i keep in our un-heated guest room are still good. About 55ºF.

This is what i'm growing now...the top pic. 4-6 small trays every two weeks. Fast growers. 8-12 days to the table. I have four varieties of peas and three radish. Fast growing--crisp and meaty.

I'm also growing hydroponic salads, thai basil, genovese basil, mint, this year. But that is another topic.

Oh, good to note,... your strip lights can be fixed on the upper shelf. No need for the hastle of moving them up and down on chains. (pain in the he-ha). Just put younger seedling trays on a boxes or books to get them higher to the lights.

This pic is dated 11-2019. Obviously a big salad timed for a Thanksgiving salad. I rarely use the bottom shelf unless a holiday/big bbq.

@agmss15 those are the brand i was looking at. can't tell how many lights you have on each shelf? if multiple, how far spaced apart?

FOAS, we all have our own way of doing things.

This past few years, the pandemic, natural disasters, geopolitical manmade disasters, uncertainty of sufficient infrastructure where we live, --------- etc., Food security is one of the concerns. I have decided to prepare as much as I can, and as practical as I can given limitations of living not too far from NYC.

I do microgreen to full grown vegetables and fruits, Lighting requirement goes from 0 to full artificial sun (LED lights). O foot candles for sprouting, low level lights for typical microgreens, and powerful LED lights for everything else.

I have installed a (DIY) solar system for my lights (artificial sun). I need a lot of light, so space is a consideration. I made my LED lights (posted here sometime ago). Each, based on measurement with a watt meter, draws 407 watts, yet each only measures 8" x 6". On a sunny winter day There is enough solar power to drive 4 x 407 watts of lights. Which also gives me 4 x 407 watts x 3.41 BTU = 5,551 BTUs of free heat for the house.

In general, I don't worry too much about color of light. I want Watts. Lots of watts and I want light that's comfortable for my eyes. LED Watts are cheaper than the ideal colors, and plants like lots of watts.

The lights you posted takes a lot of space and installation for 80 watts. You can also use reflective mirror sheets (Mylar, Space Blanket) to significantly increase lighting level.

I never concern about growing conditions for better nutrition. I am more into more variety and better taste. We are in an overly vitamin-ed life style in this USA.
