The reason why you need the straw is being they don't have enough soil to root out. You need to transplant those into at least 1-2 gallon pots depending on your grow space. And remember to water around the rim of the soil in the pot to prevoke roots to grow outward and not just down. And with what transplanting experience I have with outdoor grows of both mj and normal flowers and plants, making numerous transplants is a hastle and another open opportunity to stunt or damage your plant(s). You might want to check out the CFLs grow section if you are cramped for room/stealth. Cute spot to start some seeds though lol. Good luck to you
