1st grow with diy rdwc

So far this week I am starting to germinate 4 seeds. 2 are blue dream matic and the other 2 are pineapple Express auto from Fast Bud genetics. I also did a leak test on my diy undercurrent rdwc set up. I should have seedlings by the end of the week. Update 1. Both blue dream have 1/2inch tap roots and 1 pineapple Express has a 1/4 inch tap root. The other one has just opened up. Hopefully that doesnt mean they are going to be slow growers. Update 2. Sorry I dont have any more pictures this week. I dropped my phone and now my camera doesn't work. The 2 blue dream matic are about an inch tall and in rock wool. The 2 pineapple Express auto have not sprouted yet. The tap roots are slowly getting longer. I think it may be the temp of the seed starter. I purchased a seedling mat and have them on it. So hopefully I will have 2 more sprouts. I also have been fighting with fixing the leaks in the buckets. So I bought some flex seal spray and it worked!
