4x5x7 homemade tent using 2x4’s, Mylar sheeting, a 5 level utility shelf with only the top and bottom shelves installed and a chain hanging from a hook drilled through the top shelf. We got a 600w full-spectrum LED with cooling fans and hung it from the chain. To change light height, just move it up & down the chain.
We got autoflowering blueberry from ILGM. I started 4 seeds in a wet paper towel using filtered water that I set ph to 6 using phUp/Down. I used a digital ph meter with temp reading to get it right. I put the folded paper towel w/ seeds in a ziplock bag, then wrapped that in a black plastic bag, and put it on my cable receiver, which runs warm but not hot. The seeds started to split after 24 hrs. They had taproots after 48. I soaked rock wool cubes and squares of coc mat in ph6 water with just a touch of Botanicare Pure Blend Pro Grow for about 4 hrs. I moved the seeds to the rock wool cubes, taproot down and set them on the squares of coco mat in a Jiffy starter tray and put the lid on. I set this on a germination mat and set the LED to about 5 inches above the lid. I set the light timer to 18hrs on, 6 off. That was 4 days ago and this morning I found them ready to move to their big grows. 1-2 inches tall with 2 sets of leaves. I’ll be doing that today.
I’m setting up to do 2 5-gallon deep water hydro systems and 2 4-gallon pots of Mills Coco Coir.
I’ll post again later with details on the nutes and amounts I end up using and maybe some pictures of my setup.
