yes, you need good ventilation....you want to get yourself a fan of some sort to push the air around. I would use a solid material if you are going to build a box. Transparent materials would not be good when flowering....you want COMPLETE darkness!

Most indoor grows veg the plant for about 3-4 weeks depending on the amount of space you have. And watering should be done every 2-3 days depending on how dry your soil is. If you put your finger in about 2 inches and it's damp....wait till tomorrow. If it's dry....it's time to give them some water.

You shouldn't get any seeds if the plants are female. But it can turn hermie if you mess up on the light cycle or if there are any male plants in the area.

And like str8outtaweed says....get some books or get online and find what works best for you. There is a lot of information out there and tons of resources available. This is a great place to get advice as well.....good luck man! :jointsmile:
moody420 Reviewed by moody420 on . First time growing, a lot of questions... Hey there, so the time has come to grow my first plant.. first of all, about the box: 1. should i better use transparent material or should plywood be ok? 2. how many holes do i need for ventilation? should i use a computer ventilator? 3. should i use a fan to make it warmer in there? i will use classic wolfram light, i think it generates a lot of heat..
