Absolutely, the purpose of the grow bag is to weep the moisture from the ground. If you have the bags on a different surface than bare soil/(non-permeable) you're not using them the way they were intended to be used. You could actually use a bathroom scale and weigh the bag filled with soil/ and planting before watering. Get them all around the same weight, remember or record. Totally saturate the bags, wait until all water dissipates from around them/ excess water drains out and weigh them again, record. You will know exactly how much moisture/medium they hold (8lb/1gal). Over the course of the next days/weeks depending on your conditions, if you go so far as to monitor the weight via the scale or just pick them up to see how heavy they feel you will learn when they (??)

Boondie seeds sells them but are out of stock. Contact them and see when they might have them back in stock. Or try others on the internet.

Last year I had a great crop of Scotch bonnet peppers from a plant that was given to me and I saved some of the seeds. How do I start making seedlings and when do I start planting them for this year?

To get many fruit from chili plant you need to plant a new plant every year. Last years plant have excessive leaves and very less good sized fruit. In tropical climate chili plant produce fruits up to three or four years.

I agree .best to plant a new one each year, fruit is bigger. Ive done lots of growing experiments with chillies in Auckland i had a jalapeno plant kept for 4 years in a pot which was babied the whole of its life .. only occasionally did it produce several good size fruit the smaller fruit i used in making sauce`s or cooking Another factor i found is dont grow different varieties close to one another as they can cross pollinate, If you are collecting seeds from the fruit for the next season. You may get smaller fruit

Tammi - could be mice or rats, they can do this also. Its happened to me in Perth. Megan - Chillies will only grow vigourously during the warmer months, depending on where you are, they will either slow down, go dormant, or die altogether, depening on how cold it gets, a severe frowst will kill them. Wait until summer, they will flower all over, and give you lots of fruit. If you want a hotter chilli, water them less, let them dry out a little (but not all the way). A stressed plant will give hotter fruit. If you want hotter fruit still, get a different variety. Look for a chinense variety. Gareth - Most people raise chillies in punnets/starter pots, then into medium pots (10-15 cm across at the top), then onto final larger pots or garden beds when they have outgrown the medium one. You can tell when they are ready to be moved as they will have roots coming out the bottom. Julie - feed them with tomato food, probably in liquid form, is pretty good for flowering chillies, also, mulch and compost the soil if you can. Murray - depending on the variety, chillies can take up to 6 weeks to germinate, and they also need warm humid conditions to do so. Chillies are originally grown in warmer humid places, so they better you can recreate this, the happier they are. Keep them moist, (but not wet or soggy), perhaps put half a coke bottle over them to keep the humidity up, put them somewhere warm, they dont need sunlight to germinate, so the top of the fridge will do. When they do germinate, move them to a sunny windowsill or similar until they are ready to be hardened off to go outside. Michael - an NPK ratio of 10-5-10 for when they are growing works well, then 5-10-10 for flowering, if using bought fertilizers. Otherwise, a well composted mix of garden waste should work well, with some animal manure thrown in. Dont forget to mulch the soil to stop evaporation.
