the hps is fine, just dont get it too close at such an early stage
Thanks for the advice keeko, I agree pretty much every few days for most seedlings, this issue really is dependant on the pot size, so I apologise for not saying.. pictures below

The sprouts are taking in as much water as they can, and generally the heat makes a difference. Even with an AC unit helping to control the climate in the room, if it's not making the small distance from the light to the seedlings the same ambient temperature, even a slight elevation in heat will cause more evaporation.

If you're using a lot of perlite or vermiculite, or a good deal of any other aerating agent, you'll end up watering more frequently. If this is the case, some peat moss - or a similar moisture retaining substance - should be added the next time you transplant...but you should be careful how much transplanting you do. It's easy to shock the roots by doing it too much. I transplant twice; from 4" germination pots to 10" pots, and then later to a 5 gallon bucket when I know what's going to be staying.

One last thing, make sure the light isn't too close to the tops of the plants by using the back of your hand. You're going to want to get that HPS as close to the plants as possible to reduce stretching. Seedlings can stretch easily, which will generally lead to them falling over. When this happens, I like to make temporary stakes using about six inches of a clothes hanger and bending a horizontal "U" shape on one end. Helps you from having to tie any thread or string around the expanding stem.

Good luck with your grow! :jointsmile:
I am not sure of the exact pot size, but I know its quite big!

Truth be told these were germinated in tissue and then as they popped (~12hours) they were placed in the biobizz all which is a wee bit strong for them I admit, but they seem to have done okay. As you can see they are a bit spindley and they were transplanted from very small cutting pots into this big mammoth, I may keep all 3 in the 1 pot and make it `mother` or later transplant (so thats 2 transplants altogether, if I don't make these mothers' right?) :-)

BTW: Currently in limited space at the moment, as I am still in process of making the grow environment (box or w/e). Thats why they are all in one pot!!

AS you can see from the picture it does look like one of them has been overwatered a bit? Either that or I damaged it slightly planting it. Yesterday I added the straws and (carefully) added wire to hold them lightly in place.. guessing its a case of overwatering , roots, shock to the system, or the HPS light being a bit warm (re one is drooping a bit).

I actually moved the HPS upwards a bit so now it's over 18 inches away (approx 2-2.5 feet now) do you think thats a bit too far away?

Thanks for the advice and good wishes! This is still work in progress so lets see where it goes man!

Thanks,

Seedlings 10 days old- a log Hi guys, I am a new member here, since a few weeks ago, I have read many of the articles and FAQ's and I apologise if this is covered somewhere else on the forum (I have looked, honest ;-) Having some BIG PROBLEMS - with my seedlings, they've just turned 10 days old. They germinated in 24 hours thanks to much great love from me! They have recently been transplated because they seemed to be unhappy under a 400 Watt HPS grolux lamp..
