Cheap LED light to start seedlings?

[exploziv]

I would go with 2 x 9-15 W for more surface. 18w in a single place is a bit much and makes your lighting less efficient, cause u need to keep it further away. Than will take care of 1-2 handfulls of seedlings for a few weeks.

thinking bout a 100w led floodlight, closet is pretty small so it will fit ideally. are there any base guidelines on the distance between plants and lamps? and if so where could i find those, reading some contradictory stuff

Again, I would go with 2 x 50W rather than 1 x 100. But even the 100W one will do, but probably you will have to keep it over 50 cm away. I mostly used 20W ones and they were great and could be kept at 15-20 cm away no problem. One of those would have enaugh power for at least 4 seedlings up to week 3. So.. depending on how many seedling u plan on growing.. maybe 2 of 20-25W would be enaugh? Make sure they are real power and not some kind of equivalent with less real wattage. Also, I would go with brand ones if possible. At most, you would need a mains plug, a knife and a flat screw screwdriver to install a mains plug on the wire they come with.

Good advice.

Multiple small units are better than one single big one. Cheaper, easily swappable, less waste heat generated, and better coverage/penetration. I have a little veg/mums space with 2 small LED floodlights, bolted onto a rough diy wooden frame, with a 4 gang extension stuck onto it with gripfill. Cost bugger all.

How about this light? Par38, 20W. It might be suitable for 3 babies.

The domestic lamp is managing 110 lumens per watt. This puts it in the low end of the market, where the globe part is a real hindrance due to manufacturing costs. With the globe lopped off, you can expect around 150 lm/w

The flood panels use smart cobs. 80-100 lm/w

This means two of the 18w lamps will equal a single 50w flood.

Just one 18w is ample. Look in the local adds for an old angle poise.

I've used Screw in LED's, got 2 big panels with 70 or 100 lights.

They work good, light-wise.

Last time I grew indoors, maybe 2020 ?, the mites took over and there were no lady-bugs available at the store.

Lack of natural predators for spider mites I think is one of the biggest problems with growing indoors, but not in-solve-able.

I recommend buying Safer's CONCENTRATE, then mixing up Dunk Tanks.

Dunk the whole plant.

If you buy the Safer's spray bottle it's only good for minor infestations.

Some 50w QB's are 25$ delivered. Quite shocking really. Mixed 3000k 4000k 660nm UV&IR. I bet the driver reaches more homes than KDFM, but soo cheap

Heard mars hydro is devolping compact leds? For mini grows or just more economically challenged home growers?
