'fixing' bending stems on lettuce
First off, thanks everyone for contributing - it has helped a newbie like me tons. Here is my deal: have (2) small 3 gal. bubbler systems going, on about week 3 from start of germination. I have 4 lettuce seedlings that I am concerned about because the stems of all of them are bending over. I currently have them propped up with cocktail toothpicks, but need to have a more permanent solution.
So, first need to know why this happened....
I have a 175 watt MH above at about 18", air temp is 70F, humidity at 50%, pH at 5.8-6, and TDS at 380.
I know lettuce sometimes bolts, but I germinated under cooler temps to help prevent this. What do you think?
Next, I think to 'fix' these stems I will try to put about 3/4" of additional rockwool around exposed stem (spliced down the middle) and kept together with a rubberband aroud it , basically to help support. Have I confused you all enough? Thanks in advance for all of your help!
