Pumpkin Plant Update

I'm getting very anxious to get my pumpkin plants in the ground. The plants have gotten large enough now that it is getting difficult to get them under the grow lights. This morning we woke up to snow on the ground in Denver and the large range forecast is for temperatures around freezing this coming weekend. I'm debating putting them in the ground on Wednesday. I can keep the plants warm enough that they should survive but I'm struggling with whether it would be better to keep them in their puts a few more days or get them going in the ground. I re potted the plants on Saturday but I don't think I can go much beyond this coming Saturday before I run the risk of getting the roots bound up.

Below are pictures of all of the plants except for the 1528 Starr. Click on the picture for a larger view. The first one is of all of the plants. It is interesting to see how similar the last two plants and the first two plants are. The first plant is the 1236 Harp. The second plant is the 1161 Rodonis. Although they are separated by three generations, genetically they are pretty much the same with 1068 and 998/1231 in them. Other than the 1236 has the crinkled leaves those two plants are almost identical in size and shape. The next two plants are the 1129 Orleck and the 1316 Harp. Both of these plants have 985 in them so I would guess that is where the larger leaves are coming from. The 1528 is equally doing well but the wind started to come up when I was taking these pictures so it didn't make it outside. All of my plants are ahead of my plants from last year at the same number of days but they are a touch behind where I think they should be. I'm not sure my grow lights have enough wattage and the weather outside has been cold, overcast and windy so they haven't gotten much direct sunlight yet. The color on all of the plants look good however so they aren't doing to bad. Leave a comment below to tell me which one's you think I should grow...
