You really think they’ll triple in mass though?
There’s 250 watts of CFL on em mixed red and blue , and there’s 110 of LED above those (which isn’t as concentrated obviously ) but u really think they’ll get that much bigger
These here plants grew under 24/0 and switched to 12/12 about 14 days old.
This is 3-4 days later and they went another 10 days or so after this before starting to flower.
I don't have a good picture at flowering because i started lst some 3 weeks in and i am glad i did.
I think they more than tripled in mass in the 2 weeks after being flipped to 12/12.
Light was about 100 watt led.
I think it's pretty normal for seedlings to put on that much mass in the weeks before showing sex and starting to flower.
When flowering starts many strains double in height in the first 2-4 weeks of flowering.
I think the pot size will limit their height but i guess your plants will end up 10-15 inches tall lest you train them.
