i am not an expert either,

A: your light for this stage is ok
B: it seems that you water the whole of the pot
C: it's ok the size of the pot.....don't think it matters so much....at least you will not have to transplant....the plants i grow have been from the beggining into 2 gallon buckets and now, after 4 weeks into veg they are over a foot tall
D: i agree with kuri....leave it unwatered (so the pot dries)put your finger in it to sense the moisture.....water only if top 2 inches are completely dry...... 24/7 under the light but not too close to the plant (put your hand in between to sense the heat nad adjust the distance when it is comfortable), you don't want to burn it, after a few days you will see some growth...
E: do not water the entire pot....it is not nessesary as the plant is very young and does not have grown so much root yet.....
F: to understand better what we mean, the plant will search for water by itself and therefore will grow as a result!
newgroweroldsmoker Reviewed by newgroweroldsmoker on . I feel like an idiot... Heres my plant. I dont know why, but the lil guy just wont grow. Its been two weeks but nothing. I've been keeping the soil moist and not watering till it becomes dry again but still, nada. As for lights, im taking it out in the day and putting it under a grow-blub I picked up at a nursery by night. Rating: 5
