why won't they GROW???

3 days is not long. the plants will grow under any light. You just get better results with different spectrums and intensities at different times of growth. Be patient . What kind of water you using? Is it balanced as far as ph?

Try to not worry and give them a chance to survive even if it takes longer than you think~

but was reading about how root development increases if you use 18/6? It makes sense to me; plants evolved to have a night-time, not 24h sunlight. but if you think i should switch back to 24h, i'll do that tonight.

I don't think you should do anything, I was merely suggesting as you stated that your plants are not growing, it's a known fact that 24/7 speeds up the growth process, I also heard the same, that root development is not as good, however my plants are doing fine and appear to be healthy. if you want to see an increase in your plants growth I recommend 24/7, if you are not in a rush then stick with what you've been doing.

Also I'm thinking it would be a good time to repot those two in the window seal in larger pots and burry the stems to the first set of water leaves.

thanks for all the help everyone. this board is much more helpful than cannabis.com, where no-one answers the questions os newbies like me.

My plants look like yours but have started developing alternating nodes. They are about 3 weeks old now. I'm pretty sure our goals are different. I'm looking for MILFs and you are looking for buds..
