Time To Transplant?

I have this plant I am growing from some sseds I kept out of a pretty good sack. It is about a week old now, and in like a 5" pot. Should I go ahead and move it into a larger pot, or is it too soon? Also I have been keeping it like 1 inch under 1 40 watt flourescent light, and one 40 watt aquarium light 24/7. watering it every 3 days like half a cup Doing good so far, I think. first timer, any advice would help thanks.

Yes, it will be okay to transplant now. It's fine to put a seedling straight into a big pot as soon as it has sprouted. The bigger the pot the better, 15 litre pots are probably the best.

Putting the seedling straight into a big pot is the best way to do it as the plant never has to repair itself from the shock of transplanting. Make sure you water quite close to the stem at first, let the leaves direct where you water, just outside the leaves should be fine as the roots will not be able to access enough water to begin with. At least, that's how I'd do it next time. Like yourself, I did transplant (a couple of times) due to space and we kinda rushed into it. Find the biggest pots you can, we used 11 litre buckets (because they were cheaper, and originally we needed to buy 80) and melted holes in the bottom. Then there's the soil. However big the pot is you've got to get the soil to fill it. It nearly killed us doing 40 (the amount we have ended up with). Hopefully we have more than 20 females.

and also, when you transplant you can bury the stem a couple inches up as well. this will keep it shorter if space is an issue. ive done this before when my power strip got unplugged and they did some major stretching

I built up the soil a bit too because my plants had stretched to much and fallen over, usually just building up the soil was enough to support the main stem. Now they're strong as anything.

any tips on transplanting without disturbing the roots?

grab the main stem between your index and middle finger, turn the pot upside down while still holding the stem between your fingers. then squeeze the sides of the pot to loosen the soil up if you can. if not, gently pull on the stem and the soil and roots should come out in one piece. be sure not to water the day before you try to pull it out otherwise itll be all muddy and such. then just make a hole in the new soil large enough to fit the whole mess into. be sure to water it down well afterwards.
