          Funnily enough I actually use grow lights for my monsteras. The thai has more stability with variegation so it's not as important. Also I have found it needs humidity or the light will dry it out a bit too much.
          Works well for my Albo and Aurea.

    Nice discount for these.
    I've seen a couple in action and they appear to work well.
    I have a competitor brand and I'm considering switching.

    My germination rates on my seedlings is way better using a grow light and heat mat combination.
    Seedlings don't go leggy as well with a good grow light.

    I currently have strawberries, bok choy, spinach, lettuce and red onion seedlings under a grow light and they are going so well.
    I even had 3 capsicums germinate under the light in the last week or so as I had an old cell with raising mix sitting with cells I did fresh sowing in.

    Grow lights are huge with vegies growers overseas now, but are still a bit of an unknown here and I recommend you researching them if you want regular success with your fruit and vegie seedlings.

    Also research the kinds of light and terms like full spectrum, as there is some cheap rubbish out there on the market.
