Agh, all the contradicting suggestions LOLSuperthrive is just vitamin B1. It's fine for seedlings. That dome is creating another heat trap I think. How is air supposed to circulate around the plants? The temps have been your biggest issue so far. Domes are only really necessary for clones. Do have a thermometer in there? The distance of your light would be good for a 400watt hps but 150watt I think you can move a lot closer. Just make sure you have plenty of air moving between the light and your plants.
Here is the other chart for metal halide, they match.Thanks for all the help man... yeah not trying to negate yours (or anybody's) feedback, just trying to find what works!
I did move the girls closer about 2-3" might play with a couple more here and see I found this chart that seemds helpful
Day 20/5:
Things are going good, went and got some superthrive and a humi-dome today from the shop. Was debating the superthrive, but all three at the shop said it wouldn't hurt at all... so just recently mixed some superthrive in a spray bottle and sprayed all the babies good.
The biggest change since yesterday was the height, especially on the new 4... they gained about 1-2 inches since yesterday morning... stretching too much? I know before I was told mine were too short :-/ the 150 HPS is about one foot now from the girls, about 6-8" from the top of the dome.
Will be leaving town for the night for Halloween, hope all will be good... no.. make that great when I return LOL
Think this is where they should have been at 2 weeks?? I'm thinking I'm a week behind...???The older ones are definitely looking a lot bigger and better.
