• Dear Guest,

    We've been using a forum format called vBulletin for over seven years and the program is no longer being developed, so that means no more updates or security patches. vBulletin has never been compatible with search engine optimization and it does not support the multitude of various devices most people use to access the internet, so it's time to say goodbye to vBulletin.

    For these reasons we have moved our forum to a new format that will support and encourage growth for the next generation of grower and DIY tobacco users.

    So please post any issues you're having with using the new site.

    As usual, you may login with your old password.

EVALUATION OF FLOAT TRAYS WITH HIGH CELL NUMBERS ON STAND COUNTS AND YIELDS IN A CLOSE-GROWN TOBACCO PRODUCTION SYSTEMhttp://www.tobaccoscienceonline.org/doi/pdf/10.3381/10-005.1
It's actually quite good to read about some trials that have been done before about closer spacing. .I've been discussing this with springheal (phil) for the last few days..as we have quite limited space..last year I grew them close (v.g) some as close as15cm..and still got good leaf as the plants work around each other..so this year I'm trying a number of growing distances on all different types..even wrapper types. .so I'll see how things turn out at the end of this grow attachment-8.jpeg

I will be looking for compost for my float trays in a few days I need some advise
from what I understood the right compost for float trays is mainly pure peat moss mixed with vermiculite or Perlite right?
nothing else? should I ad some Earthworm humus to the mix?
I my mind the proper mix should be made of 75% pure peat moss + 25% of vermiculite am I right?

hey leverhead just finished my mix, 2 gallons of uncompressed peat moss to alf a gallon of vermiculite
what do you think?
I would add another 1 1/2 gallons of vermiculite, I use equal parts of peat moss and vermiculite (50/50). If cost is a problem, use pearlite. I don't think pearlite holds any moisture, vermiculite does hold moisture. I think the only other thing that vermiculite or pearlite do in the peat moss, is to keep it from settling (packing) too much in the cells over the 6-8 weeks that seedlings are in there.

hi costs are not a problem, I'm just afraid we can be speaking about different particle sizes, can you post a pic of your mix please?

back, now I need another advise, are we supposed to water the trays from the top the first time? or I should just wait the moisture to go up?
