1st Seed Grow Journal-2007

1st grow pics.

Setup: Ebb and Flow Baby Bloomer-6 gallon resevoir with 1 gallon pots.

Ph-5.7

ppm-unknown

temp: 75.8-79.6

humidity: unknown

Oscililating fan on low for strong stem growth.

Lights: 400 watt MH switchable to HPS.

Light Cycle: Day 1-10 24/0...Day 11-17 18/6 due to heat stress from 24/0.

Full Str Nutes from seedlings. (Ph levels were at neutral 7 for first 10 days, then I finally got me some Ph down to adjust to 5.7

I over fed in the beginning and some of my plants died. I was feeding 4 times a day at 30 minute intervals, I then changed it to twice a day at 15 minute intervals, seems to be plenty. (Irrigation cycle)

Bag seed grow, random strains.

Day 1-3 Germinate

Day 4-8 ph 7.0, 4 irrigation cycles at 30 minute intervals, lights on 24/0 at 12 inches

Day 8-12 ph 6.8, 3 irrigation cycles at 15 minutes, lights on 24/0 at 24 inches.

Day 12-15 ph 5.7, 2 irrigation cycles at 15 minutes, light on 18/6 at 28 inches.

temps averaged from 72.4 F to 81.2 F.

No humidity gauge

Still looking for a tiny screw driver to check ppm with this pen I ordered.

So with a drain and flood system...is it true I don't want to add nutes for the first 2 weeks? Just use 5.5-5.8 ph balanced water? How many times should I be feeding a day? and for how long? How far should the 400 watt MH light be from the tops of the plants? What should the PPM be at throughout these days?

Any advice is welcome!

Oh and one more Q, is it going to cause a problem that they are so damn close to each other? Thanks for the replies!
