I’m new to this forum and new to growing cannabis. I germinated a seed a few days ago using rockwool. The sprout is about 2" in height, but I still do not see any leaf forming. In any case, I placed the new sprout in the rocks of a 5 gallon hydroponic system that’s setup in a small closet. The pump is timed so that the rocks are moistened for about 1 hour a day.
Here are my questions:
I am currently using LED lights to provide light to the plant. What schedule and light color do I need to use as the plant goes through its full life cycle?
How important is it to provide ventilation when growing in a closet? What should the rate of air exchange be?
Any other suggestions for a healthy plant growth?
I apologize in advance if these things were discussed before. Please feel free to copy the links as a response.
For veg you can use 3000k-4500k. For flower you’ll want 2800k-3500k. 3000k-3500k can be used for veg and flower. Are you growing autos or photos? I run my photos 18/6 in veg. If you’re running autos, you can run anything from 12/12 to 24/0. Mine are in with my photos until the photos flower, so my autos get 18/6 from seed to harvest. Got pics of your little one?
I’m growing an auto. Pic is below. Sorry, what do you mean by 12/12 to 24/0? Also, does the color of the light matter? I read somewhere red light is good for sprouts until they become bigger.
Blue light is better for Veg stage, Red light for flowering stage. Seedlings drink from the air mostly, make sure you raise humidity to 70-75%, put a clear dome or cup over your plant if you have to. Mist it 3-4x a day if you can.
I don’t think 1 hour a day is good enough. Can you change it to water 4 times a day for 15? What is your schedule? I don’t grow hydroponic so I’m not sure.
No. If I put a fan, I’d need to keep the door open all day. So I was trying to see if leaving the door open just at night would be sufficient for providing fresh air.
You need a fan for air circulation inside your grow too, not just air exchange. Leaving them open at night should cover the exchange, but you still want the air inside your closet or tent to be circulating while it’s closed up.
