just caught up on reading thru this grow. i haven't tracked down prior grows of yours to read thru yet so i hope you don't mind if i ask a question or two. this is a 12/12 grow from seed correct? what soil do you use? its been a cold winter, do you have to heat the grow area? if so, how are you doing that? i have a couple more things but i'll pm them to you and not clutter up your journal. thanks for sharing your experience. if i'm going to finagle a grow someday, i'm going to have to jury-rig a space some how and its really good to see how other people approach their spaces and the challenges those spaces give. on the twine thing, if you take some cardboard, preferably a double sheet, and tack it to the board so it wont shift, it will provide a smoother, less angular surface for that twine to lay against than the corner of the board. agree with the idea of doubling/tripling of the string too.
