While I agree w/Not a #, in that you can certainly grow them indoors and under normally available lighting, but I do
not see where anyone here suggested needing "insane levels of light" this time!
I know that in other posts it has been suggested that you can't successfully grow thriving VFT's indoors under lights. In years back, as a kid, I myself always grew under lights, and more preferred, in a south facing window, so I know for a fact it can be done. Especially with the CFL's and all the better lighting choices available today. But indeed do get yourself better lighting.
I guess perhaps some people have not had the success that others of us have had. Also, perhaps we all have different ideas of what "thriving" is for a plant, and what we are willing to accept as "growing". Keep in mind, there are varying degrees of "success" in growing plants. I think we can all agree that your plants are showing a need for more/better light. Anything you can do to improve that situation will help... and the better you do at giving them more light....between where you are now and "
insane levels of light"... will ultimately help!
Also, it seems they are seedlings, which if they are, makes growth a bit funky now anyway. You may want to transplant some into other containers down the line, (if you then have more lighting anyway). As someone mentioned about replacing your planting medium, the plants you have look quite crammed in together, and that will also make for poor growth! When you get better lighting, divide them up to give them more room for their roots!
It looks like straight peat you have them in. (It is hard to tell what planting medium someone planted their plants in from a picture.) If so, when transplanting and dividing, I would be sure to use the proper planting mixture.
(If you don't know what mixture to use, read the posts about that or look it up on a site... the info is all over, and it is not for me to do your work of reading up about the basics and this sort of thing.)
[I don't point the finger at you directly concerning this, but so many people here, depend on learning the basics by simply asking a handful of questions and assuming foolishly that they can learn everything they need that way!They forget that you are only going to get "
opinions" here, and that everyone has an opinion, even fools! And indeed we watch the blind leading the blind every day!] Again, I am NOT assuming you fit into this category.
(I only mention it because as N.A.# is obviously tired of hearing people say you can't grow VFT's under normal artificial lighting, I myself am tired of lazy people thinking they can learn about a subject by simply asking strangers a few questions.)
Concerning your plants...I would also get other plants to put around them and to share the "excess" light with, as having some plants "around" them will help your VFT's to hold more humidity and make for better growing conditions. (A "full" greenhouse holds humidity and good conditions better than a near empty one.) Just be sure to keep the prime lighting spots reserved for your VFT's!
Good luck! Do the best you can! Your plants are living organisms, and they are counting on you for their lives!
