@mjumbo, Hmmm. Well. Then, if you're going to be changing spectrums daily. I'd highly suggest you get a light that meets the RA spec. "That's the suns value" viparspectra has much more warm light. But very good grower. The spiderfarmer also has a good spectrum. Both have dif diodes. I think the SF has a more sun like spectrum. But if you wanna get closer to the suns ppfd marshydro TS1000 150w would be great. It has a coverage of 90cm2, and core coverage of 60cm2 for flowering. You need to be in a range of 8-1000ppfd for flowering anything above 1000ppfd you need to match the value if its higher with co2, is it solely for veg?
What is your outside weather like?
Any of these lights. You'd be best off vegging the thing under it for all of its veg. As I assume you have low RH?. You can veg your girls right up until its the hottest part of your Yr. Giving your plant an extra ppfd boost. As the sun moves are you 1 sided on your balcony? I
