This is my first time grow. I am trying to educate myself on lighting to make sure I keep my girls happy during their different stages of growth. I have a vivosun vs4000 full spectrum led grow light. I was trying to find information on how the full spectrum works during the different growing stages (seedling, vegetation, flowering). I have read that during the different growing stages plants need more of a particular light spectrum. I could not find any good information on the net. Most just contained specs, unboxing, and a few unhelpful reviews. So, I figured I’d come to the experts. Does the vivosun vs4000 address different light spectrum needs during the different plant growth stages? I can only change light percentage, is this how vivosun vs4000 address the need for different levels of color spectrum during different stages of growth?
If it’s full spectrum, you’re good to go all the way from seedling to flower. All you need to control is ppfd and dli. Download the photone app, set it to full spectrum led, and it will get you in the ball park. Here’s a couple of guides to use to set it per plant stage. The first one is ppfd, and the second is dli.
Thank you for the information @Dexterado
No problem. I just recently switched to an hlg 350r, and just learned about dli and ppfd. I think it’s very helpful, and important. Plus it saves a lot of electricity since you don’t need as much light until flowering.
@hmfischer25 I have the same light. The Manual has the different settings and respective distance for each stage of growth. Do you have your specs? I can dig mine out and post a pic if not. I am finishing up what appears to me to be an excellent run with this light. I think you’ll enjoy it as well!! Happy growing!!
Thank you @Fieldofdreams. I do have my specs that the light came with. I just wish it had more of an explanation of how they worked. I found that I need to put the light closer to my seedlings because if I don’t, the lil’ buggers like to stretch. I will attach a picture of “Abagail” my Hawaiian strain. I will probably have to have a support her in a few days to keep her from falling over. The other girl right next to Abigail in the picture is “Blue” my Blueberry strain. The girl in the next pot is “Wanda” my White Widow strain.
@Fieldofdreams Hey mate, sorry I know this is an old post but I recently purchased the same light and am wondering how many plants I can grow with it in a 5x5 grow tent? What’s really weird is that Vivosun sent me a “grow kit” package with my tent, and it came with this light. Their website made it sound like I could grow up to 10 plants in my tent on this one light, and I’m finding that that is most likely not correct and not near enough lighting… how many plants have you been able to grow on this one light? And what size is your tent?
I was using the Vivosun in a 4x4 originally and I think a 5x5 would leave the edges of the tent in the shade. I have a Spider Farmer 7000 with UVA bars in my 5x5 now and it fits the dimensions better. I ended up adding a SF4000 to the Vivosun4000 and they work great in tandem in my other 5x5. I can send you some pics later of my tent ceilings for the layout if you’re interested.
If you wanna scroll through I have images buried in here lol.
Definitely interested and I will check all of that out! So should I not just go with another VS4000?
I am running 3 300w in my 5x5. Had 2 HLG 550r before. 1 would not do it. 600w or better i think for a solid flower of that space. Just me.
How many plants do you think a single 400w can even grow? You think I’ll be good to just get another 400; 800 total for a 5x5?
You definitely could. I got so much negative feedback here in the Forum from peeps hating anything Vivosun and Miracle Grow that I started exploring different ferts and lights this year trying to improve.
Here’s the VS4000 SF4000 in my 5x5. I recently threw in the 2 VS1000 for flower. The plants seem to like it.
Looks great bro! And yeah I’ve noticed people hating on Vivosun a lot. I don’t get why, I feel like this is a pretty good light. A lot better than the Hydro Mars 400 that only puts out like 170 something watts lol
Try saying publicly your having a good grow using MG products and watch the negative feedback compound lol.
I can grow about 4 to 5 plants but I grow autoflower which are smaller than photos. I ended up buying a bigger tent and getting another light. Same one. They work good for my needs. My only complaint is they do get warm.
