good info from everyone. Thanks !
My GH daytime temp is usually in the mid 70s. Night time is 62 to 65. That may drop a bit when we get the occasional 22 degree night.
The rope lights are incandescent. I've only been running them nights for the last 5 days or so but sounds like I will have to keep a close eye on that as the plants may get too much light. Think I will put them on a timer and maybe let them start running a few hours before dawn, when it's the coldest, and then off, as opposed to all night. That would then give them 12-14 hours or so a day when combined with daylight.
@sooby I will pay more attention to the shift In Temp between night and day. Part of the problem may be our shifting weather between cloudy and sunny and I haven't made any changes to accommodate that.
@rickcorey great idea on the sequential plantings. Think I will do that and keep a log of what planted and when. Should yield some great info. I hate to give up so soon. I really want dinner from the greenhouse!
I will post again in a couple of weeks and let ya'll know how it's working out.
