Grow log #2!

:thumbsup: I took a closer look, it's now 3 out of 5 sprouting out! :thumbsup:

Yeah i am quite intreagued too, if your 12/12 start to finish works, that would save a lot of electricty!

Are you using the 150 HPS throughout without adding any more light? if so how are you positioning it for the 5 plants?

Good luck though, gonna be watching!

That's the plan, 150 watts is close to optimal for the wardrobe size I use :hippy:

if so how are you positioning it for the 5 plants?

Right now it's about 1.5' - 2' right above the seedlings

Good luck though, gonna be watching!

Thanks, though I'm hardly the first to grow 12/12 from seed:

And we have 3! :thumbsup: moistened the soil and lowered the light a bit more, I don't like the babies to be too leggy from the get go. Hopefully the lower HPS will help the remaining two seedlings to pop out of the soil.

Raised the HPS a rung or two - the hot spot it made on one of the foam cups was making me uncomfortable. Foam cups 4 and 5 still aren't showing sign of life...but if my last grow is any indication, 2 seeds I believed dead sprouted late in the vegging cycle, so I'm not discarding them yet.

I still have my old "popcorn pots", but since I have 5 seeds in the works I needed 5 pots that would fit at the botom of the wardrobe.

I think I found something suitable (another save from the Dollar Store!). On a side note, the sprouts are looking a bit leggy for my liking, but for all I know, that might be normal for a 12/12 grow from seed using a HPS fixture...

It's only day 7 so I'm sticking to plan A. Just in case, I did get me a pack of KC Brains Afghani Special I'm keeping on standby. If the (current grow) Oasis turns out well, I'll use the new seeds for my next grow.

This is called lessons in growing with HPS lights folks - what happened is entirely my fault. I commented earlier that the sprouts are a bit leggier than I'd like.

Well, to be precise, one of the three (the first one to pop out of the soil in fact) was, looked long and frail even.

My idea of lowering the lights to avoid legginess backfired, like, bad... sprouts #2 and #3 are ok, but #1 has all but shriveled up from the heat and dry soil (yet I've been punctual at keeping the soil moist) ...

So I've raised the HPS fixture back to a safe distance (about 1.5 -2' above the foam cups), made sure all 5 foam cups have been properly watered and decided not to discard #1 yet...it may be futile but if the roots are still in good condition there is perhaps a chance to salvage that leggy one?

And still no sign of life out of seedlings #4 and #5 ... here again I hesitate to discard them: during my last grow, 2 seedlings I believed dead sprouted after a week or two as the other plants were already tall and strong (one turned male, the other was a girl) ... so... if I've learned one thing from my micro grows is that patience is key.

Keeping my fingers crossed!:hippy:

Tough luck Pedro.

Personally, I would not turn on that hps until the babies were about a week old. From the time you plant your seeds until one week old, you waste a lot of electricity for nothing. You might look into getting a couple cfl's just for the first week or two, the hps is notorious for killing seedlings...

Good luck!:jointsmile:

That's the thing: I have CFL's coming out the yin-yang from previous grows, I wanted (as an experiment) to do 12/12 from seed using the same lights...I have read about growers using HPS throughout rather than switching from Fluo or MH during vegetative to HPS for flowering...

Not having a proper light fixture for my 125 watt CFL doesn't help matters either. But...given the shaky start this grow is having, perhaps switching to CFL until sexing would be the right thing to do? :wtf:

No I don't think you have to wait that long. My first grow I used a 21w flouro for less than a week just until it the new leaves came in a little, then put it under the hps and double the normal height. Technically, you could sprout them with the hps, but they should be pretty far away, I'd say at least 2-3x farther than normal. Then, gradually, lower the light. It's not very efficient, but it should only take a couple weeks until you get the light to the final 50cm mark (less if you have a cooltube, of course). The 50cm is just a recommendation from a friend. Without the cooltube I kept it at 40cm from the light, max.

Well...reviving that shriveled sprout may be a waste of time...ditto with keeping the two foam cups awaiting for a late awakening of seeds 4 and 5 ... a second set of leaves is showing on sprouts 2 and 3 so that's a good thing.

What I may end up doing is repot seeds 2 & 3 but leave the foam cups 4 and 5 in the grow cab anyway just in case; I've had late sprouters before. Sprout #1 ... if t's a lost cause that was entirely my fault.

But if seeds 4 and 5 are non viable...I'd expect better than a 60% germination rate from Dutch Passion and their boasted "superior genetics". For that rate I might as well save my cash and stick with KC Brains seeds (with whom by the way I had a 70-80% germination rate) ... just sayin'...
