Sprouts 'closing up'...?

Voodoo Chile · #1 (**permalink**) 04-17-2007, 09:17 AM

Howdy folks!

Growth on my week-old sprouts seems to have stalled and I'm getting concerned by how their cotyledons and first leaves are so vertical.

Here's some pics:

The first two are Durban Poison, the third is a complete unknown (bagseed).

Pics are dark because I turned the f-stop all the way down on my camera so that the image wouldn't be overexposed. I've actually got them about 1"-2" from a 200W 6400K Envirolite-type fluoro like this one:

Should be enough, right? Too much? I've got them on 24/0. I've done the back-of-the-hand test, warm but not hot at plant level.

Temps in my ghetto cab (upgrading soon) have been steady at 22-25 C/71-76 F, humidity at 50-55%. A 10" fan is blowing a decent breeze from about 3' away (I've left the cab doors open).

Potting soil is my main concern: Before I'd done enough research I'd planted my germed seeds in a pH 6.5 cloning/clipping mix of peat moss, bark compost, and perlite with some supposedly "light" nutes:

Fertilizer 0.5Kg/m3: NPK 16.7.15
"Agrosil" (root nutes) 1 Kg/m3: NPK 2.20.0 + 45 SiO2
Guano 1 Kg/m3: NPK 13.10.2

I regret using this soil; as soon as/if they get big enough, I've got organic Biobizz AllMix on the on-deck circle for their transplant.

I've only watered once, yesterday on the 6th day post-sprout and after making sure the soil was bone-dry more than 2" down. I'm using distilled water with pH 7.0 (checked it with my digital pH meter). The watering doesn't seem to have affected them either way.

Feel free to dispense some o' that fine GC wisdom. Either way, thanks for checking in and best of luck with your own grows!

Ha, yeah, perhaps too nice. This morning I upped the light another inch and increased my fan speed; by this evening one of the plants had relaxed noticeably. I guess one can get too close with a fluoro, especially a 200-Watter in a batwing.

Watered them a bit as the soil was once again bone dry.
