I am having a hard time finding the troubleshooting thread to fill out the form, so I will try my question here (and if anyone knows where I can find the troubleshooting form, plz let me know) We are starting to get concerned with our seeds and clones. Over the last 2 years we have not really had a problem with seeds or clones, until recently. We put them under the dome and once we place into the tub (we grow hydroponics) they just seem to stop growing. The clones just seem to stay small and wimpy looking. The seeds stretch for the light, and most of the seeds pull themselves up and grow nicely. We follow all the step when cutting clones, but I am wondering if the change in tempuratures from day to night could cause this? We do have air/heat control in the rooms but I just can't figure out why the clones aren't growing and why the seeds grow so slow. Thanks to all those that read and those that give any suggestions. Thanks
