OrganicPanic Posted January 18 Share Posted January 18 Hi! Any help super appreciated! Got some of these LED and currently have one at 4’ and one at 3’ in veg at 100% Getting some leaf curling etc. I understand from the manufacturer they can go as low as 50-60cm! If anyone has experience with them please let me know what heights your going with. Thanks in advance x Link to comment Share on other sites More sharing options...
Shumroom Posted January 18 Share Posted January 18 Have a look for PAR maps for your light They’ll give you a better idea of power settings and height for each stage of growth Atb Link to comment Share on other sites More sharing options...
MindSoup Posted January 18 Share Posted January 18 (edited) How much light you can give your plants relies heavily on the quality of your environment, so keep that in mind when adjusting your light. It's worth doing some homework. Bruce Bugbee and Migro on You chube will tell you everything you need to know .

MindSoup Posted January 18 Share Posted January 18 (edited) Did it come with a manual? They're normally in there. As for the lux thing, we measure PAR (photosynthetically active radiation) not Lux. Basically the part of the spectrum that the plants use. However with a few different lux meters you can use the guide below to accurately work it out. http://www.uk420.com/boards/index.php?/topic/420079-cheap-accurate-par-readings/ Phone apps are pretty unreliable, their light sensors aren't really up to the task and different phones have different sensors so theres a lot of inconsistencies. Gives you a rough idea though. Like I say, check out those channels and you'll soon know what your doing. Migro is a bit better to learn the basics in bite size chunks, what to do as apposed to why to do it. Bruce is good for when you want to go right down the rabbit hole and deeply understand what's happening why's, how's, when's etc Edited January 18 by MindSoup Link to comment Share on other sites More sharing options...
OrganicPanic Posted January 18 Author Share Posted January 18 (edited) Thanks mate I really appreciate the help. I cant open that link for some reason? This is a second account as has to do another due to security… maybe it’s because I haven’t got enough posts yet. I will watch the videos soon as Im back indoors. Thanks for all your help Edited January 18 by OrganicPanic Link to comment Share on other sites More sharing options...

Shumroom Posted January 18 Share Posted January 18 You could try the blindness test Atb 1 Link to comment Share on other sites More sharing options...
OrganicPanic Posted January 18 Author Share Posted January 18 (edited) Hahha!!! I will get a proper PAR reader.. tried one on phone just to see and got readings around 2,600 if that means anything to anyone Im off to check out the vids Edited January 18 by OrganicPanic Link to comment Share on other sites More sharing options...
MindSoup Posted January 18 Share Posted January 18 2600 PAR? Even if it's a very vague phone estimate that's waaaaaay too much. 1000 is pretty much the maximum you'd go without CO2 supplementation. I run about 300 for early veg about 500-600 for later veg and about 750-850 for flower 2 Link to comment Share on other sites More sharing options...
OrganicPanic Posted January 18 Author Share Posted January 18 Yeah these phone ones are crap tbh the plants look good! I cant open link to good PAR meters if anyone got some suggestions for cheapest ones it would be appreciated x Link to comment Share on other sites More sharing options...
