I ave just started my 1st grow n i am beginning with Alaskan Ice i hope i have ave picked a good 1, My room is 12x7x8 n it is covered in ADF Mylar as this is 95% reflective.
I ave got the bubblepot system which is set up but not yet connected, a 4" extractor fan with carbon filter & a 18" cooling fan as the heat in my room is already 30degrees.
I seeded 25 Alaskan ice for 48hrs n then put then in rockwool into a propagator only 20 of theses have gone into the propagator which are now on day 3 the rest ave not done anythink so i am assuming they r dud 1s,
I have noticed that there is 10 of these which r now 1-1.5" high ave got brown tips on there leaves does any1 no why this is???

Are you using some type of fertilizer? Don't. Seeds have all the nutrients they need to get to 4 full leaves and 2" tall easily before you even begin to give very mild nutrients. As they age more then you start to ramp up the nutrients, but not while they are little seedlings. If the room is too hot it will also do that, all they need is some flourescent lights not some hot HID's until they are plants rather than seedlings.

Thanks for that I have just put the fan on just b4 I logged on do you reckon I put the extraction fan on aswell as the room is very hot 30+ degrees & I have opened the vents on the propagator to try & harden them a bit, do I need to do anythink else as I really really dont want to mess up as ive spent a lot of money on this
I have attatched sum photos from 10mins ago & they are now on day 12 in the propagator, thanks for the help

Oh well its on day 15 propagation & today is the 3rd day I have took the propagation lid off it will be for an hr & half today so they can gently be hardened off seems to be working & strengthening the stems to scared to look at the roots just yet will leave it a couple more days I had a couple of plants going very dry looking so I have been misting them with plain water but I am debating on mixing some rhizotonic to mist them with.
They are growing a lot slower than I expected has any1 else grown Alaskan Ice because I would b very interested to know how they went on with there grow
