30 watt - amzn.to/2JFmu8s - Jak na to + styl
Very cool vid Peter. I loved the time lapse.
Thanks, Jared!
Great time lapse and cool experiment 👍🏻
The 30watt seems to have smaller and fewer leaves but started to flower first. I assume the one on the right had more than enough leaves for the light to produce its flower. The 15watt needs bigger leaves to absorb more light to produce its flower.
The aim for these plants are not to get big leaves but to flower and then seed.
I grow Tropical plants for the foliage. The higher the watt the smaller the leaves; usually. My experience.. maybe not the same for these kind.
You make some great observations. Thank you!
I'm working in plant ecology and wanted to report right the same. Smaller leaves and earlier flower can be seen as better light conditions. You can find the same with plants species growing on open grasslands or in shade. In my opinion the higher watt goes a bit better since you can leave a bit more space between light source and plant and even might be able to place some more plants under one light source.
@@botaniker6644 thanks for sharing this. What happens if you use the 30w, but continue to cut off the flowering buds? Would it be better for leaf growth?
but if you're growing basil for the leafs not the flowers, once it flowers the leafs turn bitter.
People always tell me that my plants (mostly aroids like monstera, philodendron,...) have smalls leaves because I didn't give them enough bright light to grow bigger. Now, after reading your comment, I'm so confused....
Good work Peter! Keep it up!
Thanks, Richard!
Mmm... Holy basil. Growing some now. Those flowers and the leaves makes great tea and taste good blended into creamy dip recipes. Thanks for always making the best content, PS!
Super preview! Thanks!
Thanks for watching!
Nice test. Great little lights. I started growing with white leds in 2011.
Light wont scale the leaves. Ive noticed basil doesnt like a lot of water.
Be well today.
Thanks for watching!
Great video, but the plant on the right is stressed. The light should be twice as far away to account for the increased power. Essentially, the larger lights give wider coverage, meaning you can put more plants under 1 light when the light is further away from the ground.
HI, seem the video is long time ago, may I ask did you figure out way to fix / prevent damage /burn leaves issue?
The best thing is to have an accurate PAR meter, and use that to adjust the light distance or intensity.
Hi ,on your experience ,what you reccomend for ome plant ,the 30w o the new one 70 w ?
Personally I would go with the 70 watt. I've had great results with it.
@@pepperdactyl Sincerly i dont think its penetracion light is inough like a hps or hm. Maybe it work until 20-30 cm ...you should try if it work with plant 1-1,20 tall with leafs around.... Only than you ll be sure...
@@nicolassocci4311 Yes, it depends on your needs and other factors too. I have run HID lights before, and they do penetrate much more, but they generate lots of heat and cost more electricity. It's a trade-off.
@@pepperdactyl i think the gold standard now is the mhc (lec) lamp...they such less energy for the same light power ..give a Look.
why would leaves closer to the light dry out....these bulbs emit almost no heat or UV.....
They do put out some heat, the sides get pretty hot.
The 15 Watt plant looks way better, bigger and nicer. How can it be?
I don't know. The 15 watt has a more focused beam, maybe in that small setup scenario, it pushed more growth.
Ja I believe the light Prism is smaller therefore more intense? I also saw that the 15W is heller? Is that the 2Pak from Amazon? I need a light that cast wider but with enough power to stimulate growth. I am so confused. Thanks for the video.
have you tried the 40 watt ?
No, I have not. I think it would be preferable to the 30. The way the 30 and 40 are diffused appears to cut the intensity quite a bit. I imagine they could server a larger footprint though. The 15 works surprisingly well.
seems like they are putting far red in now as well
That's cool. Please let us know how it works for you. I'm a fan of the HLG boards. I haven't used one yet, but know some people who have.
yeah i'll let you know im in the uk so it might take a while to get here :)
30w is much better the plants did not retire and they bloomed first the 15w plants stretched a lot
Yes, I think it was a trade-off. The 15 was much more focused, higher PAR within a tighter area. The 30 spread more light over, more diffused.
@@pepperdactyl I heard 2019 model of 15W is more diffused. Have you tried it?
@@Athenal0ve Yes, I have it. It is more diffused. Here are two videos I made on it. czcams.com/video/UUt8Bxht6Uo/video.html czcams.com/video/tnYtcEQSgsw/video.html
If its 30 but 23 get back at sansi
