Ok so not really my first grow, my 2nd. My first that isn't gonna end in disaster though Have set up a new grow room which you can check out here. So one week ago I put 2 Big Bud and 2 Holland Hope from SensiSeeeds in for germination using the paper towel method in a airtight plastic container wrapped in aluminium foil and left on a heat mat. Within about 4 day one of the Holland hope had about 1" of a tap root and I transplanted to pre-PH'd rockwool and popped it into a propagator with some very mild nutes and placed on a heat mat in my clone box (under 6x20w cold cfl's) After a week this is how she is looking. Now I have never gown in rockwool before and now the tap root is coming out the bottom I'm wondering what is my next step? Should I put some mild feed inthe tray and let the roots develop some more in the propagtor or do I transplant to the next medium now? Now the other 3 seeds have been in the same container under the same conditions and they are only cracked with not a whole lot else going on, any ideas?
Bad news. Could not sleep last night so I turned the fans for the clone box off for a few hours. 6x20w CFL + 2 x heat matts in a 20" x 30" mylar lined box with no fan = bad times. The one seedling that has sprouted is we and truly BROWN, If it survives I'll be amazed. Such a stupid thing to do This is how she's looking. The container the seeds were in was also pretty hot, so theres also the chance that I've steamed them . They still look the same cracked with a tiny head poking out but no big roots like the other. Anyone any ideas on how I can spur them on? I'm going to try 4 more seeds tonight using the drop in water method to see if I can get better results. Still looking for some advice on what to do with the seedling in the rockwoool cube, do I keep i in the propagator another while (considering the scorching I gave it, or do I move it to a small pot?) Thanks again.
So the seedling died and the 3 other seeds halted at where they were I think I steamed them Total plank! Anyway I have another 4 Hollands Hope and 3 Big Bud germinating right now. Going to muy some Canna Coco Nutes as don't want the hassle of messing around with the Aqua stuff I got, I'll keep that for some other time. (might do a wilma grow next time and use up the nutes and clay pebbles ) Now my two local grow shops stock either u-gro coco (€18) or playgron coco (€15) does anyone have any thoughts on these brands as I can't find a whole lot about them online.
So went with the plagron and the Canna nutes. I'm going to use the AirDomes on this grow (I might leave them out on 1-2 pots just to compare but I don't want to experiment too much on my first grow). I have also filled the bottom of the pot with about 1" clay pebbles to stop root rot. Now here is my question. Do I have to mix the coco with Perlite for aeration, can I use some clay pebbles instead? Do I even have to mix it at all? Answers on a postcard.
